Three-Dimensional Transformations
When creating an effect involving rotation of the image, you can
use the spin function to specify the number of rotations of the
image. Using the ROT button in normal rotation mode, the image
may not rotate correctly about the required axis, but using the spin
function you can create effects in which the image rotates about a
specified axis.
Use the following procedure to use the spin function to specify the
number of rotations of the image.
1
To set the number of rotations in the source coordinate frame,
press the SRCE button in the function allocation section,
turning it on.
To set the number of rotations in the target coordinate frame,
press the TRGT button in the function allocation section,
turning it on.
2
Carry out either of the following operations.
• Hold down the SHIFT button in the key frame operation
section, and press the ROT button in the transformation
mode selection section.
• In the 3D TRANSFORM menu (menu page 601), press F7
(SPIN), turning it on.
For details of menu operations, see Chapter 4. For specific
details of the 3D TRANSFORM menu, see page 9-3.
3
To cause a spin about the x- or y-axis, turn the trackball.
To cause a spin about the z-axis, turn the Z-ring.
To exit from the spin function, press F7 (SPIN), turning it off, or
press one of the buttons in the transformation mode selection
section.
