Custom geometry for acceleration structures
I would really like to use acceleration structure for my custom AABB geometry (I am writing a voxel engine). Is it possible now? If not, I would like to know when this feature will appear.
it's not implemented yet and listed as part of the tracking issue:
- https://github.com/gfx-rs/wgpu/issues/6762
Raytracing is an experimental feature that's still under development. Keeping this open and linking on the tracking issue instead.
I think @Jaisiero had an implementation working (https://github.com/gfx-rs/wgpu/issues/1040#issuecomment-2460208883).

Unfortunately it's not fully functional since procedural ray query is pretty involved (Niagara support?), so you need to iterate through your AS until you accept whatever you feel like it's a hit. Here's a code from Khronos fully testing: rayQuery-allOps
procedural ray query is pretty involved (Niagara support?
Naga support was added in #7047 (if that's what you're asking about).

Yes! That's what I meant. I am going to check it out. Thanks.
Edit: what's the branch that I should look into? I would like to try to implement procedural geometry support for inline Ray Query.
I know they are on trunk, I think they were released in v25 as well. If you are adding features it's usual to target trunk though.
