Another Metaballs2 update
Friday, October 25, 2019 | Permalink
I have update the Metaballs2 demo again. The main addition is a prepass optimization that reduces the total GPU time by about 33% with default settings, or up to 50% with the densest grid. The field() function is evaluated for the entire grid as a pre-pass, but only the sign is stored as a single bit, with 8 values in a 2x2x2 cube per pixel. This allows the storage to stay at a relatively modest 16MB for the densest grid setting of 512x512x512, and allows you to fetch multiple values with few fetches.
A number of improvements have also been done to the Framework4, most notably the PipelineCompiler has been updated to work with the latest Vulkan SDK.
