Visit resource ↗Description
Adaptive tessellation and subdivision is John Hable's SIGGRAPH 2026 Advances talk on compute-based tessellation and Catmull-Clark subdivision.
Topics include clamped parallelogram tessellation, seam welding, screen-adaptive density, and semi-sharp crease control without fixed-function hull shaders.
Programmers using mesh shaders or compute geometry pipelines are the core audience.
PDF slides download from the Advances 2026 content index.
Hable geometry sessions are frequently recommended when migrating off hardware tessellation.
