# baseGeometryBindTransform

The coordinate transformation for the skinner’s geometry in its default state.

## Declaration

```swift
var baseGeometryBindTransform: SCNMatrix4 { get set }
```

```swift
var baseGeometryBindTransform: SCNMatrix4 { get set }
```

## Discussion

Discussion This transformation matrix converts from the geometry’s model coordinate space to that used by the animation skeleton. It should match the coordinate space in which the skeleton (the nodes in the bones array) is initially defined, binding the model to its default pose. The default value is SCNMatrix4Identity.
