```
public final class MeshSubset

*** ** * ** ***

Defines a subset of the mesh to draw.

A subset defines a contiguous range of indices within the `https://developer.android.com/reference/androidx/xr/scenecore/MeshBuffer`'s index buffer that should be rendered together using a specific topology and a single `https://developer.android.com/reference/androidx/xr/scenecore/Material`.

| Throws |
|---|---|
| `https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-illegal-argument-exception/index.html` | if `https://developer.android.com/reference/androidx/xr/scenecore/MeshSubset#indexOffset()` or `https://developer.android.com/reference/androidx/xr/scenecore/MeshSubset#indexCount()` is negative. |
