       affine transformations.

ARGUMENTS

       ncp       number of contour points

       contour   2D contour

       cont_normal
                 2D contour normals

       up        up vector for contour

       npoints   numpoints in poly-line

       point_array
                 polyline vertices

       color_array
                 colors at polyline verts

       xform_array
                 2D contour affine transforms

DESCRIPTION

       Extrude  arbitrary  2D  contour  along  arbitrary  3D  path,   specifying   local   affine
       transformations.  As  the contour is extruded, the affine will be applied to the points in
       the contour.

       The argument "contour" specifies the  2D  contour  to  be  extruded,  while  the  argument
       "point_array"  specifies  the  path  along  which to extrude.  The vector "up" defines the
       orientation of the contour y-axis in real 3D space.

       Note that neither the very first segment, nor the very last segment are drawn.  The  first
       and  last  segments  serve  only  to  define the angle of the join at the very ends of the
       polyline. Thus, to draw one segment, three must be specified. To draw two  segments,  four
       must be specified, etc.

       The  normal  array  may  be  NULL.  If  it  is,  normal  vectors will NOT be automatically
       generated, and the object will look terrible when lit.

       The color array may be NULL. If NULL,  the  current  color  is  used.  If  not  NULL,  the
       glColor3f()  routine is used to set the color; therefore, specifying the glColorMaterial()
       subroutine before this primitive can be used  to  set  diffuse,  specular,  ambient,  etc.
       colors.
