getgpo(3G)getgpo(3G)NAMEgetgpo - gets the current graphics position
FORTRAN 77 SPECIFICATION
subroutine getgpo(fx, fy, fz, fw)
real fx, fy, fz, fw
PARAMETERS
fx expects the variable into which you want the system to write the x
coordinate of the current graphics position.
fy expects the variable into which you want the system to write the y
coordinate of the current graphics position.
fz expects the variable into which you want the system to write the z
coordinate of the current graphics position.
fw expects the variable into which you want the system to write the w
coordinate of the current graphics position. The w value is used
when defining a three dimensional point in homogeneous coordinates.
DESCRIPTIONgetgpo returns the current graphics position after transformation by the
current matrix.
When the current graphics position is undefined, the action of this
routine is undefined.
