Just checking in to see how you are progressing! Anythjng new?

Thanks for the presentation! Would there be an advantage in using mesh shaders to compute the tessellated geometry to reduce memory usage?

this is neat but wouldnt it be better to just use alembic?

Hi, very nice presentation.

I’m trying to figure out why you need the sum reduction tree to calculate next/prev in the halfedge. Is that because you allow subdivision of arbitrary n-gons? Otherwise, if we only allow up to e.g pentagonal shapes as in the example, wouldn’t it just be sufficient to look at the face-id of the halfedges in the local neighborhood? E.g for 3 in the example around 12:00, we could look at 4 immediately to see that we need to wrap, and then we look at most 5 steps (2 in this case) back to realize we will wrap around to 0.

What am I missing? Isn’t it unnecessarily slow to create the sum reduction tree for very large meshes? Say you allow n-gons, then wouldn’t it be sufficient to binary search over the half edges just comparing the face-id until you hit the upper and lower bounds?

Edge hardness coming over from blender would be awesome, but I dont think the default blend importer takes that into Unity

I'd buy a 100 dollar asset store package with this working from blender 👍
