SCNVector4

Declaration

struct SCNVector4

Overview

SceneKit uses four-component vectors to represent multiple kinds of data:

• Axis-angle rotation or torque. The x, y, and z fields contain the normalized x-, y-, and z-components of the rotation axis, and the w field contains the rotation angle, in radians, or torque magnitude, in newton-meters.

• Color value (or range). The x, y, z, and w fields contain the red, green, blue, and alpha components of the color, or the width of the color variation range in each component.
