public struct BatchDrawCommandProceduralIndirect
Remarks
This type of draw command has a reference to a material, but all vertex data is fetched procedurally by the shader. The actual draw data to be used is passed by the GPU in the buffer set up as the BatchDrawCommandProceduralIndirect.indirectArgsBufferHandle.
Fields
Value | Description |
|---|---|
| batchID | The batch ID that this draw command uses. Determines the metadata values that are available to a shader. |
| flags | Specifies rendering options for the draw command. |
| indexBufferHandle | Handle of an index buffer to use for indexed drawing. |
| indirectArgsBufferHandle | GraphicsBufferHandle of the GraphicsBuffer from which the indirect draw command will be read. |
| indirectArgsBufferOffset | Offset in bytes from which the indirect draw command will be read. |
| lightmapIndex | The index of the baked lightmap used in this draw command. If lightmap texture arrays are enabled, this value is always -1 (0xFFFF). |
| materialID | Identifies which Material to use to render the instances in this draw command. |
| sortingPosition | Together with BatchDrawCommand.flags, this specifies how to depth sort the instances in this draw command. |
| splitVisibilityMask | Indicates which splits that the draw command is visible in. |
| topology | The primitive topology to use when executing the draw command. |
| visibleInstancesBufferHandle | Handle of the GraphicsBuffer from which the draw command will read visible instance index. |
| visibleInstancesBufferWindowOffset | Offset of the visible instances buffer that will be bound as element zero. |
| visibleInstancesBufferWindowSizeBytes | Amount of data in the buffer to be bound, starting from the visibleInstancesBufferWindowOffset value. |
| visibleOffset | The index of the element in BatchCullingOutputDrawCommands.visibleInstances that matches the first instance in this draw command. |
