ClothSimulationCompute

Cloth Simulation with Compute Shader

Code Name: ClothSimulationCompute

Description

This example demonstrates GPU cloth simulation in Vulkan using a ping-pong compute pipeline, where 3 compute shaders (integration, Jacobi constraint solving, and update) run each frame to simulate a cloth grid under gravity with structural, shear, and bend constraints, plus collision against a sphere and ground plane.
