The ColorTransform class lets you adjust the color values in a display object. The color adjustment or color transformation can be applied to all four channels: red, green, blue, and alpha transparency.


The Matrix class represents a transformation matrix that determines how to map points from one coordinate space to another. You can perform various graphical transformations on a display object by setting the properties of a Matrix object, applying that Matrix object to the matrix property of a Transform object, and then applying that Transform object as the transform property of the display object. These transformation functions include translation (x and y repositioning), rotation, scaling, and skewing. Together these types of transformations are known as affine transformations. Affine transformations preserve the straightness of lines while transforming, so that parallel lines stay parallel.


The Matrix3D class represents a transformation matrix that determines the position and orientation of a three-dimensional (3D) display object. The matrix can perform transformation functions including translation (repositioning along the x, y, and z axes), rotation, and scaling (resizing). The Matrix3D class can also perform perspective projection, which maps points from the 3D coordinate space to a two-dimensional (2D) view.


The Orientation3D class is an enumeration of constant values for representing the orientation style of a Matrix3D object. The three types of orientation are Euler angles, axis angle, and quaternion. The decompose and recompose methods of the Matrix3D object take one of these enumerated types to identify the rotational components of the Matrix.


The PerspectiveProjection class provides an easy way to assign or modify the perspective transformations of a display object and all of its children. For more complex or custom perspective transformations, use the Matrix3D class. While the PerspectiveProjection class provides basic three-dimensional presentation properties, the Matrix3D class provides more detailed control over the three-dimensional presentation of display objects.


The Point object represents a location in a two-dimensional coordinate system, where x represents the horizontal axis and y represents the vertical axis.


A Rectangle object is an area defined by its position, as indicated by its top-left corner point(x, y) and by its width and its height.


The Transform class provides access to color adjustment properties and two- or three-dimensional transformation objects that can be applied to a display object. During the transformation, the color or the orientation and position of a display object is adjusted(offset) from the current values or coordinates to new values or coordinates. The Transform class also collects data about color and two-dimensional matrix transformations that are applied to a display object and all of its parent objects. You can access these combined transformations through the concatenatedColorTransform and concatenatedMatrix properties.


The Utils3D class contains static methods that simplify the implementation of certain three-dimensional matrix operations.


The Vector3D class represents a point or a location in the three-dimensional space using the Cartesian coordinates x, y, and z. As in a two-dimensional space, the x property represents the horizontal axis and the y property represents the vertical axis. In three-dimensional space, the z property represents depth. The value of the x property increases as the object moves to the right. The value of the y property increases as the object moves down. The z property increases as the object moves farther from the point of view. Using perspective projection and scaling, the object is seen to be bigger when near and smaller when farther away from the screen. As in a right-handed three-dimensional coordinate system, the positive z-axis points away from the viewer and the value of the z property increases as the object moves away from the viewer's eye. The origin point (0,0,0) of the global space is the upper-left corner of the stage.
