Three-dimensional transforms of the brick
Three-dimensional transforms using the auto cube function always
use the global channel, but for a brick you can carry out operations
in the local channel, and the shape of the brick will be preserved.
In the three-dimensional transforms using the transform control
section, you can apply deformations to the two-dimensional input
image by changing the following parameters, and the side faces
will be deformed together with the top to maintain the shape of the
brick.
Parameters adjusted
SRCE LOC SIZE (Z value)
SRCE SKEW (X and Y values)
SRCE XY-RATE (X and Y values) The lengths of the side faces change
Example of "SIZE" variation
Example of "SKEW" and "XY-RATE" variation
Note
Since there is no depth information in the side faces, it is not
possible to use an image including the brick effect for three-
dimensional intersection ("DEPTH combine").
Change in brick shape
The whole brick expands or contracts.
The side faces turn according to the
skewing of the top.
to correspond to the XY compression
ratio of the input image.
