Description

We use UVAtlas (https://github.com/microsoft/UVAtlas), which produces good results but is not parallelized and can take minutes to compute.

We have implemented a naive parallelization by first partitioning the mesh and then running UVAtlas on each part. This reduces the quality as it produces meshes with more UV islands.

  • Analyze the UVAtlas library and identify performance optimizations
  • investigate GPU porting. [Algorithms, SYCL]

Benefits all 3D mesh creation and editing tasks.

Contributor guide
