Parameters
| Variables | Description |
|---|---|
| npoints |
numpoints in poly-line
|
| point_array |
polyline vertices
|
| color_array |
colors at polyline verts
|
| radius_array |
cone radii at polyline
|
Description
Draw polycone, specified as a polyline with radii.
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 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.
By default, the cross-section of the cylinder is drawn as a 20-sided polygon. This number can be changed using the
gleSetNumSides
routine.
