NAME

transform - transform floating point coordinates and return results

SYNOPSIS

C
transform(n, pretrans, postrans)
long n;
Coord pretrans[][4], postrans[][4];

FORTRAN
subroutine transf(n, pretra, postra)
integer n
real pretra(4,n), postra(4,n)

Pascal
procedure transform(n: integer; var pretrans, postrans: Coord4array);

DESCRIPTION

Transform is a special case of clippnt with no clipping planes enabled.  Each point in pretrans is multiplied by the current transformation matrix and returned in postrans.  Since no points are clipped, all entries in postrans are valid transformed data.

NOTE

This command can only be used in immediate mode.
