NAME

scale − scales and mirrors objects

SPECIFICATION

C
scale(x, y, z)
float x, y, z;

FORTRAN
subroutine scale(x, y, z)
real x, y, z

Pascal
procedure scale(x, y, z: real);

DESCRIPTION

scale shrinks, expands, and mirrors objects.  x, y, z specify scaling in each of the three coordinate directions.  Values with a magnitude greater than 1 expand the object; values with a magnitude less than 1 shrink it.  Negative values mirror the object. 

scale is a modeling routine; it changes the current transformation matrix.  All objects drawn after scale executes are affected. 

Use pushmatrix and popmatrix to limit the scope of scale.
