# MDLGeometryType.variableTopology

The submesh’s index buffer does not contain a uniform set of primitives.

## Declaration

```swift
case variableTopology
```

## Discussion

Discussion If a submesh has non-uniform topology, its topology property contains an object describing how the arrangement of values in the index buffer combine to produce the submesh’s shape.
