GPU View-Adaptive Crack-Free Subdivision of Bézier Surfaces
Published in Eurographics Symposium on Rendering - Symposium Papers, 2026
Abstract
We present a recursive GPU algorithm for view-adaptive and crack-free Bézier subdivision. We contribute an improved memory-efficient sub-patch representation, a numerically stable and fast reconstruction of subdivided Bézier patches, a novel controllable subdivision criterion, a communication-free crack-closing technique, and carefully designed computations for producing watertight triangulations. Our GPU work graphs implementation can outperform both hardware tessellation and an implementation based on execute-indirect, while using orders of magnitude less memory. Our results demonstrate that recursive split problems map efficiently to GPU work graphs, suggesting broader applicability.
