NAME
vogle_ps - a VOGLE renderer with a PostScript device
driver
DESCRIPTION
The vogle_ps class renders an image defined with LYMB
objects (camera, lights, actors and modellers) using the
public domain VOGLE rendering library producing output for
a PostScript device. The image can be sent to an output
file, or to standard output.
SUPERCLASS
vogle_ps
MESSAGES
device_name?
Returns the string "postscript".
expose!
Overrides inherited method. The expose! message is
sent after each image has been drawn by the renderer class. It is overridden here to call clear()
in the VOGLE library, which produces a "showpage"
for the PostScript device.
EXAMPLES
The following LYMB script demonstrates how an image is
defined in LYMB. A camera is created which describes the
view. A light is created which provides illumination. A
geometric object is defined using a modeller and an actor.
Finally, a renderer is created and informed about the elements (camera, light, actor) that comprise the image. The
image is drawn by sending a render! to the rendering
instance.

Color is not supported using vogle_ps.
