Scaling the Object
You can scale an Graphic Object along the X, Y and/or Z axis to adjust the object size.
The Scale parameter adjusts the size of the object’s image up to approximately 10x its original
size. At a DMX value of zero, the image shrinks to a dot. At the midpoint of the DMX value range,
the image is normal size. When the DMX value is increased from the midpoint, the image is
enlarged. In addition, when the DMX value is reduced below the midpoint, an inverted image is
enlarged.
Tip: Use the X,Y and Z Scale parameters together to enlarge or shrink a 3-D object
proportionally.
X Scale
The X Scale parameter uses two channels to scale the selected 3-D object along the X axis,
either expanding it or making it smaller. Use it when you want to size the object’s horizontal
component.
A DMX value of 32768 (50%) sets the object at its normal size. Values less than 50% shrink the
object horizontally to the smallest at 0. Values greater then 50% enlarge the object horizontally
to the largest at
65535
(100%).
Default DMX Value: 32768 (50%) = Normal Scale
Y Scale
The Y Scale parameter uses two channels to scale the selected 3-D object along the Y axis,
either expanding it or making it smaller. Use it when you want to size the object’s vertical
component.
