Let me know if you had trouble understanding a particular thing in it or if you can suggest a better way to rephrase something!

Minor typos and punctuation are currently not the focus (will run a spellchecker later), so please forgive those for now.

Announcement for graphics programming enthusiasts!

$Sparse voxel octree ray-guided GPU streaming This is a demo of my sparse voxel octree GPU streaming/rendering engine. I used a fractal for this demonstration, but the engine handles arbitrary voxel data. Octree nodes are streamed in and out of GPU memory when the rasterizer asks for them, so the algorithm always tries to keep as few of them in GPU memory as possible. Heres some stats from this demo: Effective resolution of voxels : 4k^3, so 64,000,000,000 voxels max Total number of octree nodes in the static storage: 137M Total storage space used by the static storage: 5.4GB Maximum number of octree nodes resident on the GPU: 600K GPU memory usage: 23MB Target octree node rasterized size: 1px (unless changed by the slider)$

$Sparse voxel signed distance octree ray-guided GPU streaming Total static storage space (RAM): 2.5GB Total static octree nodes: 900k Average nodes present on the GPU: 50k SDF brick size: 8x8x8 Maximum voxel resolution: 4k^3 (building a more detailed tree would take longer than 15 minutes, but runtime performance should be practically the same) Despite this demo looking like a generic SDF fractal raymarcher, voxel data can be arbitrary. Some highlights: 00:00 intro 00:19 LOD demonstration 00:33 ray-guided culling/LOD 01:02 individual bricks 01:45 rasterization-based bricks 02:08 distance LODs 02:20 fractal hidden chamber$
