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