Instance Property

scale

The x-, y-, and z-axis scale factors of the transform relative to its parent coordinate space.

Declaration

@property(nonatomic, readwrite) vector_float3 scale;

Discussion

Together with the translation, rotation, and shear properties, this property defines the local coordinate space for any object affected by the transform, relative to a parent coordinate space. Use the matrix property to work with the complete transform.

If the transform includes time-based information, reading this property returns the scale as of the earliest time sample (as reported by the minimumTime property). Writing to this property erases any time-sampled data for the scale factor. To work with time-sampled data from an animated transform, use the scaleAtTime: and setScale:forTime: methods.

translation

The x-, y-, and z-axis offsets of the transform relative to its parent coordinate space.

rotation

The orientation, as a vector of Euler angles in radians, of the transform relative to its parent coordinate space.

shear

The x-, y-, and z-axis shear factors of the transform relative to its parent coordinate space.

- setIdentity

Sets all factors of the transform to those of the identity transformation.
