I'm considering topic of my thesis connected with computer graphics - I would compare some GI techniques which work completely in real time (no precomputation to lightmaps etc. and each frame everything is calculated anew) to narrow my topic.
I plan to compare two kind of techniques:
- based on RSM sampling heuristics (Radiance Hints)
- based on cone tracing of scene voxelization calculated in every frame (Voxel Cone Tracing)
Each technique is based on grid moving with camera in voxel size increments.
The key I think is to describe pros and cons of kind of technique in more general way. For example some other techniques are based on RSM sampling. I think two kinds should suffice.
Is there any other important or popular kind of technique which I should include or I am not aware of?
