Separated buffers for opaque- and fog volumes. I like how this is coming together! The subtle contact shadow from the fog is nice. Next up: also draw opaques into the shadow volume and then get material- and colour support to the buffers. #vulkan #screenshotsaturday #gamedev

Moved my render stages around to be able to sample the volumetric froxel fog shadows in the fragment shader as well. (exaggerated shadows in video) 🔵⚫🦖 #screenshotsaturday #indiedev #gamedev #vulkan #renderer #raymarcher

Video showing ambient light sampling enabled. Here the sky cube is sampled to affect the colour of light and shadows. The ambient pass also gives a nice AO effect to complement the shadows. #vulkan
☁️🍭

I've been moving all my volumetric lighting from the main raymarcher into frustum space - in a "froxel" volume cube.
Now the lighting is 🏎️💨 , so I can afford to make it softer and cast longer shadows. It runs in 60fps @ 4K on an RTX 2070 S.
I'm really starting to like the look of it! 🙂 #vulkan

More captures - debugging glitches for DDA and froxels.
🐛🌈 #vulkan

Dumping a bunch of recordings of interesting looking glitches and debugging I've done the last weeks while implementing dda and froxel volume for my raymarcher. #vulkan

SDF volumes at 256³ voxels. SDF manipulated on CPU (with trilinear interpolation) and rendered in compute shader. I really like that it seems to be pretty speedy still, I want all data accessible by CPU systems without readback woes. #vulkan #cpp #gamedev

Early sdf volume texture grid test with Vulkan raymarcher. 128^3 voxels (split into 8 chunks). They've gone to plaid! #vulkan #cpp

Seems to be working pretty good! 😃

Got my Vulkan project running in Linux now! #vulkan #linux
🌋🐧

Yay! Now I have a low res translucent volumetrics raymarcher with light and shadows that is upscaled to full res and glued onto the backbuffer with the help of a secondary edge masked raymarching result. Some small artifacts remain, but I'm happy and FPS goes vroom vroom! 👍 #vulkan #gamedev #cpp
