KOCMOC - a small handwritten OpenGL 3.2 core demo.
This demo was created as part of the "real time rendering" lab course at the Vienna University of Technology (http://www.cg.tuwien.ac.at/courses/Realtime/VU.html)
The video is available at http://vimeo.com/19202087
Any comments/questions are hightly appreciated and you can contact me via email of follow me on twitter @SimonWallner.
- Opengl 3.2 core profile renderer
- Loading and processing of collada files. Not all fomat features are supported and meshes must be set up correctly.
- object/world space normal mapping
- post process color correction with 3D LUT
- 2x FSAA
- Non-planar projection (spherical) achieved by resampling in the post process fragment shader
- simple shadow mapping
- simple key frame animation system
- simple property file system
- fixed/variable timestamp animation with frame export (i.e. to record movies)
- OpenAL audio
- Press F1 to see a list of commands.
- Press 'r' to reset the animation.
- Press ESC to quit.
How to build
To build the demo, download the sourc files and also additionally dowload the openCollada repo into the ./external/opencollada/ folder.
CMake is used as a build system, and it should build without problems on Windows 7 with Visual Studio 2008. VS2010 is not yet supported by collada. In order for CMake to use collada as a sub project, apply this (http://code.google.com/p/opencollada/issues/detail?id=140) patch. Executables are put into the bin/ folder so make sure to set the wokring directory accordingly.
- boost (not really, wanted to but didn't in the end.)

Parts of the source code are documented, but it mostly consists of ugly hacks, so where safety glasses and helmelts if you dive into it.
