The tutorial covers writing a compute shader for particle simulation, creating a custom URP render feature and scriptable render pass using the new render graph API, managing GPU graphics buffers, and dispatching draw calls via DrawMeshInstancedProcedural. The compute shader implements a swirling wave-like velocity field with boundary clamping and damping. Source code is provided via a GitHub Gist. ## Full article daily.dev links to this article rather than hosting it.
