    BTW this simulation/rendering engine is called BlazeFX. It's written in DirectX12. The plan is to add support for Vulkan also at some point.

    Burning fire/smoke simulation. More advanced GUI. Light scattering, that is light from the flames is cast into the smoke and lights it up.

    Very early GUI, can do multi-view simulation and rendering.

    Explosion with 1000 moving voxelized sphere sources. Simple smoke simulation.

    Despite the silence a lot of progress has been made. Now separate engine with API and application with GUI. I'll post a couple of results.

    Dug into volumetric summed area tables (SAT) The difficult part is that the SAT is done in a single pass. Two times faster on a 3090 and 3 times faster on a 6900 compared to usual three pass Here I'm using the SAT for fast box filtering with a 20^3 kernel of a 512^3 volume

    New algorithm for fast hi-res directional sharp shadows for delicate shading. Polygon model producing smooth smoke with sub-voxel precision. 512^3 / 4K

    Engine now fully implemented with DX12 (was before DX11). Rendering and voxelizing ~20% faster. Sill a long to do list, in random order GUI, SAT based lighting, combine with polygon raytracing, ... Ideas welcome.

    Just installed a 6900XT. It's twice as fast as a 3090 for computing double precision fractals (see link my very first post) That's the best thing I can say about it for the moment 😀

    Getting somewhere with my realtime skinned mesh voxelizer at 512^3 / 4K. Now this needs to generate some smoke or fire.

    Realtime voxelizer, less than 1 ms for 125 Mvoxels / 512^3 and 3.5 million triangle object. Rendering at 180 FPS / 4K. Rotation is by re-voxelizing the rotated object.

    Tested on a 3090 exactly twice faster as a 2070. At least ample 24 GB memory for large simulations. Now Microsoft or Nvidia go and fix that 2GB resource limitation, 2GB is not enough!

    New transfer function implementation, can deal with sharp gradients without artifacts.

    Single pass, second order accurate advection, yes! Faster and resulting in massive memory savings, as needing only 2 volume copies instead of 3. Next is 75 FPS, for 300^3 on a 1080Ti.
