Parameters
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.
