Class: WebGPUMesh

Defined in: packages/charm/src/graphics/WebGPU/WebGPUMesh.ts:79

WebGPUMesh is the class that manages a mesh in the GPU. It contains a set of primitives and a WebGPUBuffer where the primitives geometry is stored. It doesnt store in RAM the geometry unless it is created using the Mesh class. It inherits from Mesh class to implement some containers in case we want to create dynamic geometry.
