Unity - Scripting API: Graphics.DrawProcedural

public static void DrawProcedural(Material material, Bounds bounds, MeshTopology topology, int vertexCount, int instanceCount, Camera camera, MaterialPropertyBlock properties, Rendering.ShadowCastingMode castShadows, bool receiveShadows, int layer);

Parameters

material	Material to use.
bounds	The bounding volume surrounding the instances you intend to draw.
topology	Topology of the procedural geometry.
instanceCount	Instance count to render.
vertexCount	Vertex count to render.
camera	If `null` (default), the mesh will be drawn in all cameras. Otherwise it will be rendered in the given camera only.
properties	Additional material properties to apply onto material just before this mesh will be drawn. See MaterialPropertyBlock.
castShadows	Determines whether the mesh can cast shadows.
receiveShadows	Determines whether the mesh can receive shadows.
layer	Layer to use.

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.
