public class VkDrawIndirectCommand
extends org.lwjgl.system.Struct
implements org.lwjgl.system.NativeResource
```
Structure specifying a draw indirect command.
Description

The members of VkDrawIndirectCommand have the same meaning as the similarly named parameters of CmdDraw.

Valid Usage
- For a given vertex buffer binding, any attribute data fetched must be entirely contained within the corresponding vertex buffer binding, as described in Vertex Input Description
- If the drawIndirectFirstInstance feature is not enabled, firstInstance must be 0

Member documentation
- vertexCount – the number of vertices to draw.
- instanceCount – the number of instances to draw.
- firstVertex – the index of the first vertex to draw.
- firstInstance – the instance ID of the first instance to draw.
