I have reading a lot about the potential use of sparse voxel octrees in future graphics engines.
However I have been unable to find technical information on them.
I understand what a voxel is, however I dont know what sparse voxel octrees are or how are they any more efficient than the polygonal techniques in use now.
Could somebody explain or point me to an explanation for this?
A NVIDIA whitepaper named Efficient Sparse Voxel Octrees – Analysis, Extensions, and Implementation describes it very detailed here
