# triangleCount

The number of triangles described by the triangleIndices buffer.

## Declaration

```swift
var triangleCount: Int { get }
```

## Discussion

Discussion Each set of three indices forms a triangle, so the number of indices in the triangleIndices buffer is three times the triangleCount value.
