A rare view of point cloud voxel data

Question

Is there a c / C ++ implementation of sparse voxel representation for any dataset of a 3D point cloud?

Answer 1

Ken Silverman's Voxlap is perhaps the closest you can get.

I believe that medical devices use proprietary engines. I would also suggest that the model is actually a domain model, and the render does not visit voxels, but rather visits cells from which it can get the color value. So this is not some kind of common piece of code that gets shared.

And other voxel engines are mostly for landscape and more often in Flash. I recently saw a neat one: http://planeman-bluffersguide.blogspot.com/2005/01/testing-swf.html

C & C Tiberian Sun uses voxel bridges and encodes “skips” in one dimension, so the visualizer never checks to see if cells were empty, but simply visits busy cells.

With interest in voxels, ID Software , octtree and other space division algorithms are being considered. RTree would also be useful, perhaps.
