class MDLTransform : NSObject
Transform information can be static, or in the case of resources that describe animations, time based. You use transform objects to position, orient, shear, and scale the meshes, cameras, lights, and container objects in an asset using their transform property.
init(matrix: matrixInitializes a transform object with the specified transform matrix.
init(transformInitializes a transform object to match the specified transform component.
var translation: vectorThe x-, y-, and z-axis offsets of the transform relative to its parent coordinate space.
var rotation: vectorThe orientation, as a vector of Euler angles in radians, of the transform relative to its parent coordinate space.
var scale: vectorThe x-, y-, and z-axis scale factors of the transform relative to its parent coordinate space.
var shear: vectorThe x-, y-, and z-axis shear factors of the transform relative to its parent coordinate space.
func setSets all factors of the transform to those of the identity transformation.
func translation(atReturns the x-, y-, and z-axis offsets of the transform relative to its parent coordinate space, as of the specified time sample.
func setSets the x-, y-, and z-axis offsets of the transform for the specified time sample.
func rotation(atReturns the orientation of the transform relative to its parent coordinate space, as of the specified time sample.
func rotationReturns the orientation of the transform as a rotation matrix, as of the specified time sample.
func setSets the orientation of the transform for the specified time sample.
func scale(atReturns the x-, y-, and z-axis scale factors of the transform relative to its parent coordinate space, as of the specified time sample.
func setSets the x-, y-, and z-axis scale factors of the transform for the specified time sample.
func shear(atReturns the x-, y-, and z-axis shear factors of the transform relative to its parent coordinate space, as of the specified time sample.
func setSets the x-, y-, and z-axis shear factors of the transform for the specified time sample.
class MDLAssetAn indexed container for 3D objects and associated information, such as transform hierarchies, meshes, cameras, and lights.
