After a bit of experimenting with the boost::round functionality, the solution to the numeric instability problem was (of course) a lot simpler. The current implementation runs at 25 fps for a 600×600 resolution – pure software rendering. If you don’t know anything about volume rendering or voxels, what you can …
In the beginning of february, I started implementing a voxel-based renderer for my PhD. Starting from scratch was painful, but it taught me a lot about 3D geometry & maths and C++. To all you C++ enthousiasts out there, print this out and put it on a wall: Every time …
Whilst creating some slides on Volume Rendering, I finally found an opportunity to use this graphics-flavored version of a silly internet meme. Original found in Two uses of Voxels in LittleBigPlanet 2’s Engine from SIGGRAPH 2011, Advances in Real-Time Rendering. PDF here. I guess I did it for the lulz.
