Alright. In my next project I'm going to have separate point & vector types, as they should be. We have this at work in our C++ engine and I can't go back. This guards against things like accidentally adding together two Vector3's that represent points. #GameDev #MadeWithUnity

Inverting normals can come in handy for shaping interior spaces more intuitively. #MudBun #GameDev #MadeWithUnity #VFX

GPU-based auto-smoothing was fun to implement. Adjacency is constructed by spatially hashing & adding coinciding verts to a shared list. Then each vert's normal is updated to be a weighted avg. of similar normals of verts in the same list. #MudBun #GameDev #MadeWithUnity #VFX

Take 1 was in 2021, and this time I have some ideas to make it more performant.
Marching cubes vs. ray-marched surface. Distilled parameters down to: max steps, accuracy, and max distance. Maybe I'll add normal blur to the mix for stylized smooth normals. #MudBun #MadeWithUnity #GameDev #VFX

Ray-marched surface, take 2. Not sure why it's so much brighter than regular meshing. Even dual contouring can't beat this because it's the ground truth. Voxel density affects the proxy mesh complexity but doesn't change the visuals. #MudBun #MadeWithUnity #GameDev #VFX

Another one. Blending between surface nets or dual contouring and intermediate dual quads never gets old. The mesh is constructed & animated by sampling triangle noise with scrolling spherical coordinates. #MudBun #GameDev #MadeWithUnity #VFX

Quick & easy way to get dithered transparency to look more convincing on overlapping transparent objects: throw unique object hash/ID into the mix for noise seed. #GameDev #MadeWithUnity

Sometimes it's desired to jitter splat orientation. With high-frequency noise though, the normals might appear to be too noisy. A blend back to the original normals can help, in the same vein as normal transfer techniques for foliage in games. #MudBun #GameDev #MadeWithUnity #VFX

More documentary of the shelved experimental ray-traced voxel render mode. Splat size was used as a proxy for rendered voxel size. #MudBun #GameDev #MadeWithUnity #VFX

I tried other branching factors, but somehow (8, 8, 4) is the most performant, by a >20% margin compared to the runner-up IIRC, on my RTX 2080.
