GraphicsEngine

Framework for getting graphics applications up and running. A level of abstraction (or two, or three) up from OpenGL.

Dependencies

Building

Currently, the only build infrastructure available is Visual Studio 2010. However, the code is (in principle) cross-platform.

VS 2010

GraphicsEngine.sln should be self-explanatory.

Ensure that Visual Studio can find the libs and headers for the dependencies. Adding the necessary paths to the 'Microsoft.Cpp.Win32.User' property sheet is one way to do this. If you built FreeImage, ANN and/or GLEW as dynamic libraries, make sure that those .dlls are in your system Path (for command-line execution) and/or your Visual Studio bin directory (for running from within Visual Studio).

assimp, by default, compiles with STL iterator debugging disabled. This helps speed up a lot of file loading operations done using STL classes, but it also means that any code compiled with iterator debugging enabled will be incompatible with assimp--including any other static libraries that you wish to use alongside assimp. This is annoying enough that I've decided to leave iterator debugging on in GraphicsEngine. Thus, your installation of assimp must be built without 'FastSTL' properties enable. See http://assimp.sourceforge.net/lib_html/install.html for instructions on how to do this; it's very simple.

Usage

GraphicsEngine.lib is a library containing various useful real-time graphics utilities (mesh loading/generation, shader loading/generation, texture loading, etc.)

FLTKGraphicsApp is a library that uses GraphicsEngine, launching an OpenGL window using FLTK. Applications can extend the functionality of the basic app to do whatever they desire. Note that an installation of FLTK is only required if you want to use this; if you have a separate windowing/input management system and you just want to use GraphicsEngine, FLTK is not necessary.

See the 'Examples' directory for a couple of (admittedly rather shoddy) examples of how this stuff works. It could use a lot better documentation (especially the uber shader stuff), but I have no plans to write this any time soon.
