Cleaned up Map and the Octree. Did some testing and refactoring of generation code. Interleaved data is now good, also changed the block stack dealio to just a blob of uint64_t data. Used a GCC and by extension MSVC extension which speeds up count_bits by a good bit. After all optimizations, getVoxel is now around 10-15 times faster.

It seems that the octree has been built correctly. Going to use bitset to count children, not sure how I'm going to determine what quadrants they lie in. Perhaps masks?

little bit less on the lighting and start laying groundwork for the SVO

WORKING! Awesome! It now casts fully inside the gpu,

context is then switched to gl and then rendered via sfml.
It has no loop, no controls, and the aspect ratio is off,

There we go! The raycaster now has a camera that renders without distortion and can be pitched, yawed, and moved on the XYZ axis. I'm not sure now if I want to: Add lighting, improve performance, or start working on porting it to OpenCL

alright, tried a different method of assigning voxel step directions and I

think it's working. The 3 negative walls are still very flat, and the
lower XYZ numbers still distort the viewport

down when I start hitting negative values. I have a feeling this is going
