类
struct	GpuMesh
	Vertex/index buffers for one mesh. 更多...
struct	GpuShader
	A compiled shader: one WebGPU pipeline + layout. Also holds the WGSL sources so custom shaders can be re-pipelined for offscreen targets. 更多...
struct	GpuTexture
	Texture resources backed by a wgpu texture + view + sampler + bind groups. 更多...
class	Graphics
struct	Mesh3DUBO
	Frame UBO for the mesh3d pipeline. Mirrors the std140 layout of the WGSL Frame block and the legacy Vulkan Mesh3DUBO (so custom shader prefixes stay compatible). See wgsl_shaders.h. 更多...
class	OffscreenCanvas
	Offscreen render target (RGBA8Unorm color, optional Depth32Float). 2D batches are flushed into the canvas texture by Graphics::flush2DToCanvas. 更多...
