DCL:GRPH1:STPACK: Transformation Functions:List of Subroutines
vx, vy = NumRu::DCL.stftrf(ux,uy) Normalization transformation vx, vy, vz = NumRu::DCL.stftr3(ux,uy,uz) 3-D Normalization transformation rx, ry = NumRu::DCL.stfpr2(x,y) 2-D Perspective transformation rx, ry = NumRu::DCL.stfpr3(x,y,z) 3-D Perspective transformation wx, wy = NumRu::DCL.stfwtr(rx,ry) Workstation transformation NumRu::DCL.ststrf(lmapa) Sets the parameters for normalization transformation NumRu::DCL.stspr2(ix,iy,sect) Sets the parameters for 2-D perspective transformation NumRu::DCL.stspr3(xfc,yfc,zfc,theta,phi,psi,fac,zview,rxoff,ryoff) Sets the parameters for 3-D perspective transformation NumRu::DCL.stswtr(rxmin,rxmax,rymin,rymax,wxmin,wxmax,wymin,wymax,iwtrf) Sets the parameters for workstation transformation
There are also routines for inverse transformations with i as the 3rd character in the routine name, and parameter inquiry routines with q as the 3rd character.
