Implemented a quick volumetric fog technique in my playground project, this is screen-space raymarching (not froxel-based). Could extend it with depth peeling for transparency, 3D noise textures for variety, and render at half/quarter res with bilateral upscaling + dithering for optimization.

Alright, here it goes!
RTX pathtracing white furnace test of sponza, there some clunky artifacts with selfshadowing and non-temporal accumulatable mode bluesky can't handle well, so quickly hacked in accumulation buffer. Pretty happy with initial result, however to-do list keep growing😉|

#rtx #dx12

Finally! I can sample material information in my RTX pathtracer mode (red background). Visually both outputs albedo for comparation (RTX without mips and alpha cutoff). Took me quite a lof of heavylifting with indirect techniques. Highly recommend @mjp123.bsky.social Chapter 17 of Raytracing Gems 2
