3.2.2 Perspective Transformation

NumRu::DCL.scseye(xeye3,yeye3,zeye3) Sets an eye point

NumRu::DCL.scsobj(xobj3,yobj3,zobj3) Sets a focus point

NumRu::DCL.scspln(ixax,iyax,sect) Allocates a 2-D plane

scsprj Makes a perspective transformation effective

Other inquire routines for parameters are scqeye, scqobj, and scqpln.
