𝐂𝐡𝐞 𝐆𝐮𝐞𝐯𝐚𝐫𝐚 @chaynabors.com · 14/08/2026I’ve liked modeling these using pathfinding techniques in the past, grading on slopes and building paths where different beings consider moving between waypoints. It’s sometimes a lot more code to model things by how they look in my experience. 130 0

𝐂𝐡𝐞 𝐆𝐮𝐞𝐯𝐚𝐫𝐚 @chaynabors.com · 21/10/2025Finally, if it were me doing this work, I would want to stick with voxelized worlds for procedural content, or rasterized for statically authored. Very small chance I pick SDF for static author too depending on game. Don’t be like me and only write engine code and never sims! Forever prototyping… 110 0
𝐂𝐡𝐞 𝐆𝐮𝐞𝐯𝐚𝐫𝐚 @chaynabors.com · 21/10/2025I assume you’re thinking to author soft bodies with sdfs, with arbitrary limbs or eyes. That’s very powerful and also enormously difficult. You can in fact approximate a bounding volume for these things depending on shader, you won’t need any other acceleration structures most likely. 110 0
𝐂𝐡𝐞 𝐆𝐮𝐞𝐯𝐚𝐫𝐚 @chaynabors.com · 21/10/2025On that note, models using SDFs in this hypothetical would be like, a shader for a tree, with a seed in push constants if you can fit it, and every model becomes a coding challenge. Not impossible. Explicit data keeps the door open to prefabs, so voxels are still holy grail for generation imo 120 0
𝐂𝐡𝐞 𝐆𝐮𝐞𝐯𝐚𝐫𝐚 @chaynabors.com · 21/10/2025I’m hesitant for many reasons. I’d suggest authoring just one SDF model you’re satisfied with on shadertoy first, and then scaling that up to solve the perf issues rather than working backwards from the open world perspective. Authoring is my biggest concern, but could work depending on subject. 120 0
𝐂𝐡𝐞 𝐆𝐮𝐞𝐯𝐚𝐫𝐚 @chaynabors.com · 21/10/2025The acceleration structures fall apart if you want to start bouncing light around the scene in real time, at which point you’d be better off with an uber shader. You can’t frustum cull things you have to intersect against. You can offline calculate diffuse and SH coefficients if your scene is static 120 0
𝐂𝐡𝐞 𝐆𝐮𝐞𝐯𝐚𝐫𝐚 @chaynabors.com · 21/10/2025A lot to unpack but bounding volumes for implicit volumes aren’t trivial to approximate. You could have a shader per object, and deferred rendering minimizes work with bounding volumes for lights similarly. Subchunking and light bounds allow for lighting across chunks of uniform size. I could go on… 120 0

𝐂𝐡𝐞 𝐆𝐮𝐞𝐯𝐚𝐫𝐚 @chaynabors.com · 09/09/2025What’s drawing you to WASM? You could use the pixels crate which has an underlying WebGPU backend, but’s it’s unlikely to be easy if you don’t know Rust.
