A Parallel Scale-Space Method for Critical Features Tracking on Triangulated Irregular Networks
A scale-space pipeline for terrain represented as Triangulated Irregular Networks (TINs): scale-aware seam-free sampling, an improved TIN smoothing operator, and a fully parallel GPU algorithm for tracking critical points across scales without global sorting.

Critical Features Tracking on Triangulated Irregular Networks by a Scale-Space Method
Best Paper Runner-Up at ACM SIGSPATIAL 2024. A scale-space method that identifies and tracks topologically important terrain features directly on Triangulated Irregular Networks, handling irregular point distributions and boundaries that grid-based DEM methods cannot.
