Declaration

public static void DrawProceduralNow(MeshTopology topology, int vertexCount, int instanceCount);

Parameters

topology Topology of the procedural geometry.
vertexCount Vertex count to render.
instanceCount Instance count to render.

Description

Draws procedural geometry on the GPU.

DrawProceduralNow does a draw call on the GPU, without any vertex or index buffers. This is mainly 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 the currently set render target, transformation matrices and shader pass.

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

See Also: Graphics.DrawProceduralIndirectNow, SystemInfo.supportsInstancing.
