Spin
You use the Spin transformation to do multiple rotations about the reference
axis in the X, Y, and Z directions. Spin supports fractional values, and is similar
to Rotate when the move is less than +/- one half revolution. Spin applies
transformation values in Z, X, Y order, so editing effects in this axis order
provides the best control of the effect.
It is possible to use both Spin and Rotate at the same time in an effect. When
both are used, the transformations are nested to that the values of one are
applied after the previous transformation values are calculated. This nesting
provides increased control of the effect dynamics. Source and Target space also
affects the transform nesting order.
Option Range Description
X-Axis -999 to +999 Moves the image left or right along the horizontal axis.
Y-Axis -999 to +999 Moves the image left or right along the vertical axis.
Z-Axis -999 to +999 Moves the image relative to the viewing point; positive
values move the image away, making it appear smaller,
negative values move the image closer, making it appear
larger.
