voxels

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?

Best way of storing voxels

as seen on Game Development - Search for 'Game Development'
This should be a pretty easy question to answer, and I'm not looking for how to store the voxels data wise, I'm looking for the theory. Currently, my voxel engine has no global list of tiles. Each chunk has it's own list, and its hard to do things like collision detection or anything that may use… >>> More

Lets consider a large voxelized volume stored in an oct-tree or any other convenient structure. This volume represents, for instance, a landscape, where each block is either empty (air), or it has an specific material that will be later used to apply a texture. Voxels that are next to each other… >>> More

TL;DR -- in my first simple software voxel raycaster, I cannot get camera rotations to work, seemingly correct matrices notwithstanding.
