Sparse Volumetric Light maps (WebGPU). Pretty happy with the current state. - Improved probe placement optimization, reducing light leaks - Worked on various smaller bugs light map stats: - VRAM Size: 20Mb - Probe samples: 16,384 - Probe count: 324,674 - Bake time: 267s - Bake hardware: RTX 4090

RAW video of the air cannon launch into EF5-strength suction vortex on May 20 this year. I have finally analyzed the live data from the probe, which shows an ~80 mb drop from the Dominator, outside of the tornado, to the core of the tornado. A second dramatic dip in pressure is attributed purely to vertical velocity as the parachute probe lofts upward through the #tornado. I am working to estimate the height of the probe from our 2-3 camera angles, since the GPS failed. We are still working to recover this parachute probe!

Working on sparse volumetric light maps for WebGPU. Got generation part sorted. The resolution is adaptive, refining near geometry and skipping through most of the empty space. The video is question uses a map that's only 10MB in size, including everything. That's less the amount of GPU memory that a single leaf takes up on one of threes in the scene, or texture on one of the sign-posts. We get about 1 sample every 30 centimeters in the world space. As a side note: gave my renderer quite the workout, rendering each probe as a separate non-instanced mesh for debugging.

With efficient reallocation and defragmentation of voxels in place (see prev tweet), I recently added cascading to my irradiance cache. This enables a (relatively) low probe count without sacrificing voxel resolution near the camera. 🧵
