1.1 Getting `pov-mode.el'
You can get the latest tarball at
`'. At this site you can get the
auxiliary files for the `InsertMenu' hierarchy.
You have a second option, that can save your time. Use the
`package.el', that can be retrieve at
`'. Install `package.el', type `M-x
package-list-packages', find `pov-mode', mark it with `i' and install
with `x'. This will fetch the tarball, unpack it in `~/.emacs.d/elpa',
compile it, add the autoloads and you're ready to start, so can skip to
*Note InsertMenu::.

File:, Node: load-path, Next: Compilation, Prev: Installation, Up: Installation
1.2 Add `pov-mode.el' to your `load-path'
Assuming you have unpacked the tarball in `~/elisp/pov-mode-3.3', and
the file `pov-mode.el' resides there, you should add these lines to your
(add-to-list 'load-path "~/elisp/pov-mode-3.3")
(autoload 'pov-mode "pov-mode" "PoVray scene file mode" t)
(add-to-list 'auto-mode-alist '("\\.pov\\'" . pov-mode))
(add-to-list 'auto-mode-alist '("\\.inc\\'" . pov-mode))
These four line will tell Emacs to add `pov-mode.el' to the
`load-path' and to load it dynamically when you visit any `.pov' or
`.inc' files with the POV-Ray scene or include scripts.
If you installed `pov-mode.el' via `package.el' you don't need this
Then restart Emacs, or evaluate the lines by selecting them and type
`M-x eval-region'
If you know what this mean, evaluate these 4 lines, if it's not so,
save your .emacs and restart Emacs

File:, Node: Compilation, Next: InsertMenu, Prev: load-path, Up: Installation
1.3 Compilation
If you want to `pov-mode' run faster, please byte-compile it with `M-x
byte-compile-file <RET> pov-mode.el'. You should do so.
If you installed `pov-mode.el' via `package.el' you don't need this

File:, Node: InsertMenu, Next: Include and docs, Prev: Compilation, Up: Installation
1.4 Get the InsertMenu tree (optional)
`pov-mode' provides a GUI menu `InsertMenu' with over 200 templates
files (inc files, and templates for color, lighting, shape,
transformation ...etc). However, these templates are not bundled for
licening issues.
I suggest you to unpack the tarball in the same directory of
`pov-mode.el', so you don't need anything else.
If you don't have the permission to install the `InsertMenu' in the
same directory of `pov-mode.el' then you should start Emacs, load
`pov-mode.el' visiting a file `.pov' (even void) and customize the
variable `pov-insertmenu-location'. You can do this in two way: adding
the line
(setq pov-insertmenu-location "/path/to/the/InsertMenu")
to your `.emacs' or using `customize': type `M-x customize-group
<RET> pov <RET>', scroll down to `Pov Insertmenu Location' and indicate
the correct path. Then press `Save for Future Sessions'. In both case
restart Emacs. *Note Insert menu::.

File:, Node: Include and docs, Prev: InsertMenu, Up: Installation
1.5 Setting the Include and Documentation directories
To use `pov-mode.el' at its full power you need to tell it where can
find the includes and the documentation of POV-Ray. You can do this as
you have done for the `pov-insertmenu-location', by writing the code
yourself or by using `customize-group <RET> pov <RET>'. The variable
by default set to `"/usr/local/share/povray-3.6/include"', and
by default set to `/usr/local/share/doc/povray-3.6/html"'.
Once you're done, restart Emacs. You're ready to write and render!

File:, Node: Getting started, Next: The menu-bar, Prev: Installation, Up: Top
2 Getting started
In this mode, <TAB> and `M-x indent-region', usually bound to `M-C-\',
attempt to indent code based on the position of { } pairs and `#-type'
directives. The variable `pov-indent-level' controls the amount of
indentation used inside arrays and begin/end pairs. The variable
`pov-indent-under-declare' determines the indent level when you have
something like this:
#declare foo = some_object {
This mode also provides POV-Ray keyword fontification using
font-lock. Set `pov-fontify-insanely' to `nil' to disable (recommended
for very large files, for example a long include file with the mesh
generated by a modeller).
All the faces (and the other options) are customizable via
`customize'. Type `M-x customize-group <RET> pov <RET>'. Please see the
documentation of the faces' customization: we provide some alternatives
to the default faces. These are set to be consistent with the Emacs'
look and fill. However you are free to change it.
`M-x pov-complete-word', bound to `M-<TAB>', will try to complete
the word you are typing, according to the POV-Ray's keywords.

3 The menu-bar
This major mode has 5 menus.
* Menu:
* Imenu::
* Insert menu::
* Render menu::
* The View Menu::
* Misc menu::

File:, Node: Imenu, Next: Insert menu, Prev: The menu-bar, Up: The menu-bar
3.1 The `PoV' menu
The first, the `PoV' menu, can look strange. It tries to find the
`#declare', `#macro', `#include', `light_source' and `camera'.
If you made a lot of change please press the menu entry `*Rescan*'
to get it right.
One click on a item will move the point to that. It can be useful
editing large files with a lot of declarations and macros, or to jump
fast to the camera.
It's safe to use but can be disable by setting
`pov-imenu-only-macros' to `t' (e.g. via `customize-group <RET> pov
<RET>'), which disable everything but the macros; `pov-imenu-in-menu' to
`nil' will disable this feature at all.
It use the library `imenu.el'.

File:, Node: Insert menu, Next: Render menu, Prev: Imenu, Up: The menu-bar
3.2 The `Insert' menu
The `Insert' menu exists only if you installed the `InsertMenu' tree
somewhere. *Note InsertMenu::. It contains a large collection of
shapes, objects, whole scenes templates, etc. Just click to insert the
I'll provide you just a pair of sample files. However you can use
this feature for recycling code you often use. Simply name your template
file in the same way other files are named, and use a different number.
For example, suppose `myscene_template.pov' is your template file,
and you want to add it under the menu "Insert:Scene Template". Rename
your file to `01 - my scene.txt' (please note the spaces and the
digits), then place it in the directory `InsertMenu/00 - Scene
templates', then restart Emacs. Then, your scene template file will
appear as the first item in the menu `Insert:Scene Template'.
You can add how many menus and items you need. Just follow the syntax
`2-digits space name' for subdirectories of `InsertMenu' and `2-digits
space name.txt' for files with templates, code, and so on. Just look at
the sample files. I suggest to remove them, get the
`povray-imenu-3.6.tar.gz' (by Christoph Hormann and others) at
`' or
`', or build your own

File:, Node: Render menu, Next: The View Menu, Prev: Insert menu, Up: The menu-bar
3.3 The `Render' menu
This menu is dedicated to the rendering. Each item checks if the
current buffer has been saved and calls the executable set by
`povray-command', usually `povray', and starts an asynchronous process,
so you can go on editing while the rendering is in progress.
The arguments passed to `povray' are fully customizable and have an
incremental quality. So these command are self-explanatory. Use
`customize-group <RET> pov <RET>' to change the value of the quality,
e.g. adding switches, please remember to preserve the `%s', which will
be substituted by the file name. The menu-bar items are also bound to a
`C-c C-c r'
(`M-x pov-tool-bar-command-render')
Run `povray' without argument (default quality depending on your
`C-c C-c 1'
(`M-x pov-menu-render-test')
Run `povray' at test quality.
`C-c C-c 2'
(`M-x pov-menu-render-low')
Run `povray' at low quality.
`C-c C-c 3'
(`M-x pov-menu-render-mid')
Run `povray' at middle quality.
`C-c C-c 4'
(`M-x pov-menu-render-high')
Run `povray' at high quality.
`C-c C-c 5'
(`M-x pov-menu-render-highest')
Run `povray' at the highest quality.

File:, Node: The View Menu, Next: Misc menu, Prev: Render menu, Up: The menu-bar
3.4 The `View' menu
The `View' menu offer you two options: internal (in a Emacs buffer) or
external (using an external command).
`C-c C-c e'
Use the program set by `Pov External Viewer Command' in
`customize-group <RET> pov <RET>' (`pov-external-viewer-command')
`C-c C-c v'
(`M-x pov-menu-internal-viewer')
Emacs will display the image, if it is capable.
Please note that first it try to locate the image by the `povray'
output, then by its basename (name of the `.pov' you are editing with
`.png'). If this fails Emacs will prompt you for a filename.
If you're outputting the rendered image into a different basename
*and* your current directory has a *very long* name the `povray''s
output will be wrapped and `pov-mode' will not be able to find the
correct image (make a symlink instead, or use the same basename).

File:, Node: Misc menu, Prev: The View Menu, Up: The menu-bar
3.5 The `Misc' menu
The `Misc' menu offer some things you can find useful. Two items are
bound to a keystroke:
`C-c C-c h'
(`M-x pov-keyword-help')
*Note keyword-help::.
`C-c C-c i'
(`M-x pov-open-include-file')
*Note include-file::.
The following items are not bound because are command shared with
other modes, so someone would like to bound it globally. You can use
the `M-x comment-dwim' to comment or uncomment region). Usually is
bound to `M-;'.
`Comment out region'
is self-explaining and run the standard `M-x comment-region'
`Uncomment the region'
is self-explaining too and run the standard `M-x
uncomment-region' command

4 Tools
This major mode provides some other tools useful when editing the
POV-Ray scenes.
* Menu:
* keyword-help::
* include-file::
* universal::

File:, Node: keyword-help, Next: include-file, Prev: tools, Up: tools
4.1 The keyword lookup
The command `M-x pov-keyword-help', bound to `C-c C-c h' will open an
external browser using the `browse-url.el' library (installed in every
GNU Emacs distribution) and try to point to the documentation of
POV-Ray. It prompts for a keyword and default to the current word. The
browser is set by `browse-url', so it depends on its customization.
*Caution*: you have to set these variable:
The directory that contains the html documentation of POV-Ray,
default `/usr/local/share/doc/povray-3.6/html'.
Edit this only if the search-keyword function doesn't work! This
file should contain the general index for *all* the documentation
(default `idx.html')
Edit this only if the search-keyword function doesn't work! This
file (tested on povlinux-3.6) should contain the index for the
keywords (section 3). Default `s_97.html'.
The default paths are the default in the installation of the binary
distribution of POV-Ray. So, if you have POV-Ray installed somewhere
else you have to set these variables to a valid location.
Please use `customize-group <RET> pov <RET>' to set these variables.

File:, Node: include-file, Next: universal, Prev: keyword-help, Up: tools
4.2 Opening the include files
Sometimes you need to open the standard include files provided by
POV-Ray. The critical variable is `pov-include-dir', by default set to
`/usr/local/share/povray-3.6/include'. If you installed POV-Ray
somewhere else set this according to the valid path.
`M-x pov-open-include-file', bound to `C-c C-c i', will prompt for a
word, defaulting to the current word. Using <TAB> (completion) you will
see the include files available in the POV's include directory.

File:, Node: universal, Prev: include-file, Up: tools
4.3 The _universal_ command and the view log
`C-c C-c c' (`M-x pov-command-query') is a sort of _universal_ command:
it opens the rendered image or render the current file according to
what you have done so far. (If previous action was a render command it
display the image, if the buffer has been modified it will render).
`C-c C-c l' (`M-x pov-show-render-output') will set the current
buffer to the `povray' output.

Version 1.2, November 2002
Copyright (C) 2000,2001,2002 Free Software Foundation, Inc.
51 Franklin St, Fifth Floor, Boston, MA 02110-1301, USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
The purpose of this License is to make a manual, textbook, or other
functional and useful document "free" in the sense of freedom: to
assure everyone the effective freedom to copy and redistribute it,
with or without modifying it, either commercially or
noncommercially. Secondarily, this License preserves for the
author and publisher a way to get credit for their work, while not
being considered responsible for modifications made by others.
This License is a kind of "copyleft", which means that derivative
works of the document must themselves be free in the same sense.
It complements the GNU General Public License, which is a copyleft
license designed for free software.
We have designed this License in order to use it for manuals for
free software, because free software needs free documentation: a
free program should come with manuals providing the same freedoms
that the software does. But this License is not limited to
software manuals; it can be used for any textual work, regardless
of subject matter or whether it is published as a printed book.
We recommend this License principally for works whose purpose is
instruction or reference.
This License applies to any manual or other work, in any medium,
that contains a notice placed by the copyright holder saying it
can be distributed under the terms of this License. Such a notice
grants a world-wide, royalty-free license, unlimited in duration,
to use that work under the conditions stated herein. The
"Document", below, refers to any such manual or work. Any member
of the public is a licensee, and is addressed as "you". You
accept the license if you copy, modify or distribute the work in a
way requiring permission under copyright law.
A "Modified Version" of the Document means any work containing the
Document or a portion of it, either copied verbatim, or with
modifications and/or translated into another language.
A "Secondary Section" is a named appendix or a front-matter section
of the Document that deals exclusively with the relationship of the
publishers or authors of the Document to the Document's overall
subject (or to related matters) and contains nothing that could
fall directly within that overall subject. (Thus, if the Document
is in part a textbook of mathematics, a Secondary Section may not
explain any mathematics.) The relationship could be a matter of
historical connection with the subject or with related matters, or
of legal, commercial, philosophical, ethical or political position
regarding them.
The "Invariant Sections" are certain Secondary Sections whose
titles are designated, as being those of Invariant Sections, in
the notice that says that the Document is released under this
License. If a section does not fit the above definition of
Secondary then it is not allowed to be designated as Invariant.
The Document may contain zero Invariant Sections. If the Document
does not identify any Invariant Sections then there are none.
The "Cover Texts" are certain short passages of text that are
listed, as Front-Cover Texts or Back-Cover Texts, in the notice
that says that the Document is released under this License. A
Front-Cover Text may be at most 5 words, and a Back-Cover Text may
be at most 25 words.
A "Transparent" copy of the Document means a machine-readable copy,
represented in a format whose specification is available to the
general public, that is suitable for revising the document
straightforwardly with generic text editors or (for images
composed of pixels) generic paint programs or (for drawings) some
widely available drawing editor, and that is suitable for input to
text formatters or for automatic translation to a variety of
formats suitable for input to text formatters. A copy made in an
otherwise Transparent file format whose markup, or absence of
markup, has been arranged to thwart or discourage subsequent
modification by readers is not Transparent. An image format is
not Transparent if used for any substantial amount of text. A
copy that is not "Transparent" is called "Opaque".
Examples of suitable formats for Transparent copies include plain
ASCII without markup, Texinfo input format, LaTeX input format,
SGML or XML using a publicly available DTD, and
standard-conforming simple HTML, PostScript or PDF designed for
human modification. Examples of transparent image formats include
PNG, XCF and JPG. Opaque formats include proprietary formats that
can be read and edited only by proprietary word processors, SGML or
XML for which the DTD and/or processing tools are not generally
available, and the machine-generated HTML, PostScript or PDF
produced by some word processors for output purposes only.
The "Title Page" means, for a printed book, the title page itself,
plus such following pages as are needed to hold, legibly, the
material this License requires to appear in the title page. For
works in formats which do not have any title page as such, "Title
Page" means the text near the most prominent appearance of the
work's title, preceding the beginning of the body of the text.
A section "Entitled XYZ" means a named subunit of the Document
whose title either is precisely XYZ or contains XYZ in parentheses
following text that translates XYZ in another language. (Here XYZ
stands for a specific section name mentioned below, such as
"Acknowledgements", "Dedications", "Endorsements", or "History".)
To "Preserve the Title" of such a section when you modify the
Document means that it remains a section "Entitled XYZ" according
to this definition.
The Document may include Warranty Disclaimers next to the notice
which states that this License applies to the Document. These
Warranty Disclaimers are considered to be included by reference in
this License, but only as regards disclaiming warranties: any other
implication that these Warranty Disclaimers may have is void and
has no effect on the meaning of this License.
You may copy and distribute the Document in any medium, either
commercially or noncommercially, provided that this License, the
copyright notices, and the license notice saying this License
applies to the Document are reproduced in all copies, and that you
add no other conditions whatsoever to those of this License. You
may not use technical measures to obstruct or control the reading
or further copying of the copies you make or distribute. However,
you may accept compensation in exchange for copies. If you
distribute a large enough number of copies you must also follow
the conditions in section 3.
You may also lend copies, under the same conditions stated above,
and you may publicly display copies.
If you publish printed copies (or copies in media that commonly
have printed covers) of the Document, numbering more than 100, and
the Document's license notice requires Cover Texts, you must
enclose the copies in covers that carry, clearly and legibly, all
these Cover Texts: Front-Cover Texts on the front cover, and
Back-Cover Texts on the back cover. Both covers must also clearly
and legibly identify you as the publisher of these copies. The
front cover must present the full title with all words of the
title equally prominent and visible. You may add other material
on the covers in addition. Copying with changes limited to the
covers, as long as they preserve the title of the Document and
satisfy these conditions, can be treated as verbatim copying in
other respects.
If the required texts for either cover are too voluminous to fit
legibly, you should put the first ones listed (as many as fit
reasonably) on the actual cover, and continue the rest onto
adjacent pages.
If you publish or distribute Opaque copies of the Document
numbering more than 100, you must either include a
machine-readable Transparent copy along with each Opaque copy, or
state in or with each Opaque copy a computer-network location from
which the general network-using public has access to download
using public-standard network protocols a complete Transparent
copy of the Document, free of added material. If you use the
latter option, you must take reasonably prudent steps, when you
begin distribution of Opaque copies in quantity, to ensure that
this Transparent copy will remain thus accessible at the stated
location until at least one year after the last time you
distribute an Opaque copy (directly or through your agents or
retailers) of that edition to the public.
It is requested, but not required, that you contact the authors of
the Document well before redistributing any large number of
copies, to give them a chance to provide you with an updated
version of the Document.
You may copy and distribute a Modified Version of the Document
under the conditions of sections 2 and 3 above, provided that you
release the Modified Version under precisely this License, with
the Modified Version filling the role of the Document, thus
licensing distribution and modification of the Modified Version to
whoever possesses a copy of it. In addition, you must do these
things in the Modified Version:
A. Use in the Title Page (and on the covers, if any) a title
distinct from that of the Document, and from those of
previous versions (which should, if there were any, be listed
in the History section of the Document). You may use the
same title as a previous version if the original publisher of
that version gives permission.
B. List on the Title Page, as authors, one or more persons or
entities responsible for authorship of the modifications in
the Modified Version, together with at least five of the
principal authors of the Document (all of its principal
authors, if it has fewer than five), unless they release you
from this requirement.
C. State on the Title page the name of the publisher of the
Modified Version, as the publisher.
D. Preserve all the copyright notices of the Document.
E. Add an appropriate copyright notice for your modifications
adjacent to the other copyright notices.
F. Include, immediately after the copyright notices, a license
notice giving the public permission to use the Modified
Version under the terms of this License, in the form shown in
the Addendum below.
G. Preserve in that license notice the full lists of Invariant
Sections and required Cover Texts given in the Document's
license notice.
H. Include an unaltered copy of this License.
I. Preserve the section Entitled "History", Preserve its Title,
and add to it an item stating at least the title, year, new
authors, and publisher of the Modified Version as given on
the Title Page. If there is no section Entitled "History" in
the Document, create one stating the title, year, authors,
and publisher of the Document as given on its Title Page,
then add an item describing the Modified Version as stated in
the previous sentence.
J. Preserve the network location, if any, given in the Document
for public access to a Transparent copy of the Document, and
likewise the network locations given in the Document for
previous versions it was based on. These may be placed in
the "History" section. You may omit a network location for a
work that was published at least four years before the
Document itself, or if the original publisher of the version
it refers to gives permission.
K. For any section Entitled "Acknowledgements" or "Dedications",
Preserve the Title of the section, and preserve in the
section all the substance and tone of each of the contributor
acknowledgements and/or dedications given therein.
L. Preserve all the Invariant Sections of the Document,
unaltered in their text and in their titles. Section numbers
or the equivalent are not considered part of the section
M. Delete any section Entitled "Endorsements". Such a section
may not be included in the Modified Version.
N. Do not retitle any existing section to be Entitled
"Endorsements" or to conflict in title with any Invariant
O. Preserve any Warranty Disclaimers.
If the Modified Version includes new front-matter sections or
appendices that qualify as Secondary Sections and contain no
material copied from the Document, you may at your option
designate some or all of these sections as invariant. To do this,
add their titles to the list of Invariant Sections in the Modified
Version's license notice. These titles must be distinct from any
other section titles.
You may add a section Entitled "Endorsements", provided it contains
nothing but endorsements of your Modified Version by various
parties--for example, statements of peer review or that the text
has been approved by an organization as the authoritative
definition of a standard.
You may add a passage of up to five words as a Front-Cover Text,
and a passage of up to 25 words as a Back-Cover Text, to the end
of the list of Cover Texts in the Modified Version. Only one
passage of Front-Cover Text and one of Back-Cover Text may be
added by (or through arrangements made by) any one entity. If the
Document already includes a cover text for the same cover,
previously added by you or by arrangement made by the same entity
you are acting on behalf of, you may not add another; but you may
replace the old one, on explicit permission from the previous
publisher that added the old one.
The author(s) and publisher(s) of the Document do not by this
License give permission to use their names for publicity for or to
assert or imply endorsement of any Modified Version.
You may combine the Document with other documents released under
this License, under the terms defined in section 4 above for
modified versions, provided that you include in the combination
all of the Invariant Sections of all of the original documents,
unmodified, and list them all as Invariant Sections of your
combined work in its license notice, and that you preserve all
their Warranty Disclaimers.
The combined work need only contain one copy of this License, and
multiple identical Invariant Sections may be replaced with a single
copy. If there are multiple Invariant Sections with the same name
but different contents, make the title of each such section unique
by adding at the end of it, in parentheses, the name of the
original author or publisher of that section if known, or else a
unique number. Make the same adjustment to the section titles in
the list of Invariant Sections in the license notice of the
combined work.
In the combination, you must combine any sections Entitled
"History" in the various original documents, forming one section
Entitled "History"; likewise combine any sections Entitled
"Acknowledgements", and any sections Entitled "Dedications". You
must delete all sections Entitled "Endorsements."
You may make a collection consisting of the Document and other
documents released under this License, and replace the individual
copies of this License in the various documents with a single copy
that is included in the collection, provided that you follow the
rules of this License for verbatim copying of each of the
documents in all other respects.
You may extract a single document from such a collection, and
distribute it individually under this License, provided you insert
a copy of this License into the extracted document, and follow
this License in all other respects regarding verbatim copying of
that document.
A compilation of the Document or its derivatives with other
separate and independent documents or works, in or on a volume of
a storage or distribution medium, is called an "aggregate" if the
copyright resulting from the compilation is not used to limit the
legal rights of the compilation's users beyond what the individual
works permit. When the Document is included in an aggregate, this
License does not apply to the other works in the aggregate which
are not themselves derivative works of the Document.
If the Cover Text requirement of section 3 is applicable to these
copies of the Document, then if the Document is less than one half
of the entire aggregate, the Document's Cover Texts may be placed
on covers that bracket the Document within the aggregate, or the
electronic equivalent of covers if the Document is in electronic
form. Otherwise they must appear on printed covers that bracket
the whole aggregate.
