Hints and Compilation

The main parts of the renderer are located in src/executables/VCTGI and src/shaders/VCTGI. Some classes in src/libraries/CVK_Framework are modified, in particular CVK_ShaderSet. Empty space skipping, conservative rasterization and soft shadows can be enabled in the shaders Voxelization.geom, DirectIllumination.frag and Globalllumination.frag respectively. The code is tested on Linux and should compile with cmake on Windows too.

Please refer to my thesis [PDF, 8.9 MB] for further details of the implementation.

System Requirements
