Attraction based particle system. A shader storage buffer is used to store particle on which the compute shader does some physics calculations. The buffer is then used by the graphics pipeline for rendering with a gradient texture for. Demonstrates the use of memory barriers for synchronizing vertex buffer access between a compute and graphics pipeline
Based on a example called ComputeParticles by Sascha Willems. Recreated as a DemoFramework freestyle window sample in 2016.
Command line arguments':
| Argument | Description | Source |
|---|---|---|
