Sega Rally 95. Used to play it together with my sister like once a year at an inn on the way to our grandparents. Very nostalgic. 🙂

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

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

Screenshot from inside the fog. I'm experimenting with bluenoise to break up banding. The bluenoise is static for now but still works pretty well when rendering without shadows.

Going to try out DDA to "sparsen up" my voxel field. My hope is that it is simple and fast to implement, without having to dive into with something more complicated for now. First test just rendering the blocks. Delightfully glitchy look.

Finally got around to integrate #DearImGui into something! Up and running 1.92 in my Vulkan renderer. I'm in dire need of it atm. 😅

Artifacts. Low resolution visible in banding of the fog on the inside of the "crater" (green rectangle). But no large 4px aliasing on the edge of the sphere (blue rectangle). 👍

Current buffers. The translucent edge buffer is needed to mask the aliasing near opaque edges on composition due to the low res translucent buffer. The edge buffer contains directions as I first tried offset sampling. But it did not look good so I opted to do a second masked raymarching instead.

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
