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);

파라미터

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.

material Material to use.

bounds The bounding volume surrounding the instances you intend to draw.

topology Topology of the procedural geometry.

indexBuffer Index buffer used to submit vertices to the GPU.

instanceCount Instance count to render.

indexCount Index 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, with an index buffer.

Use the GraphicsBuffer.Target.Index target flag to create an index buffer.
