# drawMeshThreadgroups(_:threadsPerObjectThreadgroup:threadsPerMeshThreadgroup:)

Encodes a draw command that invokes a mesh shader and, optionally, an object shader with a grid of threadgroups.

```
func drawMeshThreadgroups(_ threadgroupsPerGrid: MTLSize, threadsPerObjectThreadgroup: MTLSize, threadsPerMeshThreadgroup: MTLSize)
```

## Parameters

`threadgroupsPerGrid`

An [`MTLSize`](/documentation/Metal/MTLSize) instance that represents the number of threadgroups for each grid dimension.

`threadsPerObjectThreadgroup`

An [`MTLSize`](/documentation/Metal/MTLSize) instance that represents the number of threads in an object shader threadgroup, if applicable.

`threadsPerMeshThreadgroup`

An [`MTLSize`](/documentation/Metal/MTLSize) instance that represents the number of threads in a mesh shader threadgroup.
