SUBROUTINE SETPA (PARRAY) C$ (Set Viewing Parameters) C$ Set the viewing parameters according to the 26 values in C$ PARRAY(*), as follows: C$ C$ 1-3.....View Reference Point in world coordinates. C$ 4-6.....View Plane Normal in world coordinates. C$ 7.......View Plane Distance in world coordinates. C$ 8.......Front Distance in world coordinates. C$ 9.......Back Distance in world coordinates. C$ 10......Projection type (0.0 = parallel, else perspective). C$ 11-13...Projective point in world coordinates relative to C$ View Reference Point. C$ 14-17...Window boundaries in world coordinates. C$ 18-20...View Up Vector in world coordinates relative to C$ View Reference Point. C$ 21-26...Viewport boundaries in NDC space. C$ C$ Users should normally not enter values in PARRAY(*) C$ themselves. The purpose of this routine is primarily for C$ restoring viewing parameters after a temporary change in a C$ few of them has been made locally, and the previous values C$ have been stored in PARRAY(*) by a call to INQPA.
