geometry processing

A declarative spec for unstructured mesh editing: we show a system that lets you describe mesh editing algorithms at high level while the runtime handles concurrency and robustness. Presented at SIGGRAPH Asia 2022.

Coarse yet accurate geometry with high order elements. We introduce a robust and automatic approach to convert triangle meshes to coarse high-order tetmeshes. We bound geometric error, ensure valid elements, and preserve features precisely. We can also transfer attributes and solutions between input and output boundary.
