This function is now obsolete. For non-indexed rendering, use Graphics.RenderPrimitives instead. For indexed rendering, use Graphics.RenderPrimitivesIndexed. Draws procedural geometry on the GPU.
DrawProcedural 在 GPU 上执行绘制调用，没有任何顶点或索引缓冲区。
主要适用于 Shader Model 4.5 级别的硬件，其中着色器可以从 ComputeBuffer 缓冲区读取任意数据。
CommandBuffers 中也有类似的功能，请参阅 CommandBuffer.DrawProcedural。
For non-indexed rendering:
public static void DrawProcedural(Material material, Bounds bounds, MeshTopology topology, int vertexCount, int instanceCount = 1, Camera camera = null, MaterialPropertyBlock properties = null, ShadowCastingMode castShadows = ShadowCastingMode.On, bool receiveShadows = true, int layer = 0)
For indexed rendering (takes GraphicsBuffer indexBuffer):
public static void DrawProcedural(Material material, Bounds bounds, MeshTopology topology, GraphicsBuffer indexBuffer, int indexCount, int instanceCount = 1, Camera camera = null, MaterialPropertyBlock properties = null, ShadowCastingMode castShadows = ShadowCastingMode.On, bool receiveShadows = true, int layer = 0)

Draws procedural geometry on the GPU, with an index buffer.
Use the GraphicsBuffer.Target.Index target flag to create an index buffer.
