| DE.SETF.GRAPHICS: a Common Lisp graphics library | ||
| ------- | ||
|
|
||
| `de.setf.amqp` implements a native Common Lisp graphics kibrary. | ||
| It provides 3d scene and geometry modeling and rendering in clos with | ||
| rendering support for clx, quickdraw, clim, and opengl. | ||
|
|
||
|
|
||
|
|
||
| Status | ||
| ------ | ||
|
|
||
| This library has been used for research, development, and prototyping. | ||
| Over the years, it has been built and [probed](./tests/tests.asd) in the following combinations | ||
|

|
||
| - angles, drawing arcs and rotating coordinate systems | ||
| - [clim](clim rotation +radians) transform rotations and [arc angles](http://www.mikemac.com/mikemac/clim/regions.html#3.2.5) are radians. | ||
| - common graphics [arc angles](http://www.franz.com/support/documentation/8.1/doc/operators/cg/d/draw-ellipse-arc.htm) are degrees, | ||
| - [core graphics](http://developer.apple.com/mac/library/documentation/GraphicsImaging/Reference/CGAffineTransform/Reference/reference.html#//apple_ref/c/func/CGAffineTransformRotate) | ||
| rotation is in radians. Arc perations are in radians [CGContextAddArc](http://developer.apple.com/mac/library/documentation/GraphicsImaging/Reference/CGContext/Reference/reference.html#//apple_ref/doc/uid/TP30000950-CH1g-F17001) | ||
| - [CLX](http://www.x.org/wiki/) arc angles are degrees, view rotation is computed in radians. [@xfree](http://www.xfree86.org/current/XArc.3.html) | ||
| - [Java 3D] [rotations](http://java.sun.com/javase/technologies/desktop/java3d/forDevelopers/J3D_1_3_API/j3dapi/index.html) are radians | ||
| - [OpenGL](http://www.opengl.org/sdk/docs/man/xhtml/glRotate.xml) degrees | ||
| - SVG : [transforms](http://www.w3.org/TR/SVG/coords.htm are degrees, | ||
|
|
||
| No one of them is preeminent. The internal transformation operators are implemented in radians and converted as required as arguments to | ||
| library functions. It would be possible to apply internalization/externailzation operators intrface arguments, but since the interface | ||
| exposes internal levels, it's not clear where this normalization should happen. For the meantime, use radians. | ||

| Building | ||
| --------- | ||
|
|
||
| In principle, `de.setf.graphics` is built with [`asdf`](http://www.common-lisp.net/projects/asdf). | ||
| Once one has the sources and the `asdf` configuration in place, evaluate | ||
|
|
||
| (asdf:operate 'asdf:load-op :de.setf.graphics.clx) | ||
| (asdf:operate 'asdf:load-op :de.setf.graphics.opengl) | ||
|
|
||
| to load the respective version. The versions intend to be compatible as each implements a distinct | ||
| graphics context for the respective library. | ||
| Please consult the detailed instructions for the respective [runtime](./readmes/README-build.md) for more information. | ||

| This library has evolved over the years under various copyrights | ||
| - Copyright 1988-1993 [james anderson](mailto:jaa@dtmg.mit.edu) (lgpl) | ||
| - 19880616: the original version was written as part of a research program in | ||
| design reasoning with the "design tools and methods group" in the | ||
| department of architecture and planning, massachusetts institute of | ||
| technology. the basis was mcl/object-lisp/quickdraw | ||
| - 19891107: ported to clx/pcl | ||
| - Copyright 1993-2003 [james anderson](mailto:james.anderson@setf.de) (lgpl) | ||
| - 19940528: changed element class to use standard-object classes rather | ||
| than structure-class, since structures fail to initialize correctly | ||
| with an extended subclass hierarchy. | ||
| - 20030829: ported to mcl 5.0. | ||
| introduced abstract graphics operations and opengl support, which | ||
| involved optional transform processing. simplified location implementation | ||
| to eliminate typed locations. | ||
| - Copyright 2003-2004 [james anderson](mailto:janderson@ravenpack.com) (lgpl) | ||
| - ported to allegro. | ||
