Advanced interactive volume rendering

Realtime volume rendering using:
  • Phong and blinn shading. The normal is defined by a vector going from the voxel position to the barycenter of the surrounding voxels, weighted by opacity. I got the idea in the middle of the night, thanks to a strong winter storm that prevented me from getting a good rest, but that seems to work ok :-)
  • Soft and hard shadows

Demo running on Quadro K6000 NVIDIA GPU (960x540 pixels)

Happy new year 2018!

For most people, it is a stretch of the imagination to understand the world in four dimensions but a new study has discovered structures in the brain with up to eleven dimensions -- ground-breaking work that is beginning to reveal the brain's deepest architectural secrets.
