Rotation, Position, Scale

You can independently control each Graphic Object's rotation direction and speed; along with its position and scale in X, Y, and Z
axis directions.The parameters described in this chapter are set for each Graphic Object you define. Parameters for composite
image rotation, position and global scale are described in
2.2.1

Rotating a 3-D Object

The Rotation parameters for each object control 3-D object rotation with 16-bit precision. You can rotate a 3-D object up to 720° in
either a clockwise or counterclockwise direction around the X, Y and/or Z axis.
Remember that rotation changes could affect an object's relationship to other objects.
When you rotate an object, you are rotating it around the selected axis. X Rotation produces the effect of a top-to-bottom flip. Y
Rotation produces a left-to-right flip. Z Rotation causes a circular motion.

The Rotation parameters' suggested default values are the midpoint of the 16-bit DMX value range, which is equal to no rotation.
Increasing the DMX value from the midpoint indexes the object in a clockwise direction. Reducing the DMX value below the
midpoint indexes the object in a counterclockwise direction.
When the DMX value for a rotation parameter is greater than the 720° limit in either direction, the object begins rotating
continuously. Additional adjustment to the DMX values increases the speed of continuous rotation.

Global and Graphic Effects Mode parameters contain a Prerotation Translation effect option. When a Global or
Graphic Effects Mode DMX value = 102, you can use the Effect Modifier parameters to locate the image in a virtual
three dimensional space. Applying the Rotation parameters then cause the image to orbit around the selected
axis from that location, see Prerotation Translation on page 86.
