public static method DrawProcedural(topology: MeshTopology, vertexCount: int, instanceCount: int = 1): void;
public static void DrawProcedural(MeshTopology topology, int vertexCount, int instanceCount = 1);

Description

Draws a fully procedural geometry on the GPU.

DrawProcedural does a draw call on the GPU, without any vertex or index buffers. This is only useful on Shader Model 4.5 level hardware where shaders can read arbitrary data from ComputeBuffer buffers.

Note that this call executes immediately, similar to Graphics.DrawMeshNow. It uses currently set render target, transformation matrices and currently set shader pass.

There's also a similar functionality in CommandBuffers, see CommandBuffer.DrawProcedural.
