[SIGGRAPH 2024] Vertex Block Descent

We present Vertex Block Descent (VBD), the NEXT simulator. ------------------------------------------------------------------------------------------------------- Project Page: https://ankachan.github.io/Projects/V... Paper: https://arxiv.org/pdf/2403.06321 Code: https://github.com/AnkaChan/Gaia We introduce vertex block descent, a block coordinate descent solution for the variational form of implicit Euler through vertex-level Gauss-Seidel iterations. It operates with local vertex position updates that achieve reductions in global variational energy with maximized parallelism. This forms a physics solver that can achieve numerical convergence with unconditional stability and exceptional computation performance. It can also fit in a given computation budget by simply limiting the iteration count while maintaining its stability and superior convergence rate. We present and evaluate our method in the context of elastic body dynamics, providing details of all essential components. Then, we discuss how it can be used for other simulation problems, including particle-based simulations and rigid bodies.
