MLS Point Set Surfaces

MLS Point Set Surfaces


I'm very interested in implementing basic (projection) moving least squares-based point set surfaces using Embree. However, the library seems mostly optimized for triangle meshes, so I'm curious whether my idea is possible at all with reasonable effort.

I already did the same thing using NVIDIA's OptiX library. While the implementation itself was relatively easy thanks to OptiX's support for arbitrary geometry in the BVH and fully programmable ray-surface intersection tests, the resulting performance was rather suboptimal (solving several linear systems per ray stresses the GPU's memory bottleneck).

Is Embree suitable for (iteratively refined) polynomial surface definitions / intersections instead of triangle meshes?

Thank you very much!

Regards, Tim

For more complete information about compiler optimizations, see our Optimization Notice.

The current version of Embree does not support user defined primitives directly. However, you can of course modify the code to let the ray/primitive intersection do what you need.
