# USDTransformOperation

A single transform applied to a prim, such as a translation, rotation, scale, or matrix.

```
struct USDTransformOperation
```

## Topics

### Initializers

[`init(attribute: USDPrim.Attribute, inverted: Bool)`](/documentation/USDKit/USDTransformOperation/init(attribute:inverted:))

Creates a transform operation from an attribute.

### Instance Properties

[`var attribute: USDPrim.Attribute`](/documentation/USDKit/USDTransformOperation/attribute)

The attribute backing this operation.

[`var baseName: USDToken`](/documentation/USDKit/USDTransformOperation/baseName)

The base name of this operation without namespace.

[`var hasTimeSamples: Bool`](/documentation/USDKit/USDTransformOperation/hasTimeSamples)

A Boolean value indicating whether the operation has authored time samples.

[`var isDefined: Bool`](/documentation/USDKit/USDTransformOperation/isDefined)

A Boolean value indicating whether this operation is defined.

[`var isInverse: Bool`](/documentation/USDKit/USDTransformOperation/isInverse)

A Boolean value indicating whether this is an inverse operation.

[`var kind: USDTransformOperation.Kind?`](/documentation/USDKit/USDTransformOperation/kind-swift.property)

The kind of this transform operation, or `nil` if the operation is not defined.

[`var name: USDToken`](/documentation/USDKit/USDTransformOperation/name)

The full name of this operation.

[`var precision: USDTransformOperation.Precision`](/documentation/USDKit/USDTransformOperation/precision-swift.property)

The numeric precision of this operation’s value.

[`var timeSamples: [USDStage.TimeCode]`](/documentation/USDKit/USDTransformOperation/timeSamples)

All time samples authored for this operation.

### Instance Methods

[`func timeSamples(in: ClosedRange<USDStage.TimeCode>) -> [USDStage.TimeCode]`](/documentation/USDKit/USDTransformOperation/timeSamples(in:))

Returns time samples authored within the specified interval.

[`func transform(at: USDStage.TimeCode) -> USDValue.Matrix4d`](/documentation/USDKit/USDTransformOperation/transform(at:))

Computes the transformation matrix at the specified time.

### Enumerations

[`enum Kind`](/documentation/USDKit/USDTransformOperation/Kind-swift.enum)

The kind of transform operation.

[`enum Precision`](/documentation/USDKit/USDTransformOperation/Precision-swift.enum)
