The graPHIGS Programming Interface: ISO PHIGS Subroutine Reference
ROTATE Y (PHOP,*,*,*)
Purpose
Use
Rotate Y
to calculate a three-dimensional
transformation matrix to rotate
around the y-axis using a given angle of rotation.
If the graPHIGS API can compute the transformation matrix, then
the graPHIGS API sets the error indicator to zero and returns
the transformation matrix.
If the graPHIGS API cannot compute the transformation matrix
then the values of the matrix are unpredictable and
the graPHIGS API sets the error indicator to the following
error:
- 2
- Function Requires State (PHOP,*,*,*)
