Abstract pygext.gl graphics object

Base shape object that knows how to cache its drawing routines into an opengl display list and supports transformations such as scale and rotate.

Method Details

shape.alpha(alpha) -> shape

Sets an overal alpha transparency for the whole shape. Note: only effective after a new compile.

Valid alpha values are 0-255

shape.compile() -> None

Compile the shape into a display list for quicker output. If you manipulate the shape in anyway (e.g. rotate/scale), you need to call compile again.

shape.copy() -> new shape object

Create a fresh copy of the shape that can be manipulated wihtout altering the original.

shape.execute() -> None

Execute the opengl commands to draw this shape along with all transformations.

Two-phase initialization Override this in subclasses

shape.unallocate() -> None

Free the opengl display list used by this shape.
