astInvertastInvert
-
Invert a Mapping
- Description:
- This function inverts a MappingMapping by reversing the boolean sense
of its InvertInvert attribute. If this attribute is zero (the
default), the Mapping will transform coordinates in the way
specified when it was created. If it is non-zero, the input and
output coordinates will be inter-changed so that the direction
of the Mapping is reversed. This will cause it to display the
inverse of its original behaviour.
