Module box

OpenGL boxes.

NOTE: This module has been deprecated for graphics3d.polyhedron

The box module allows creation and drawing of boxes. Boxes do not have to be cubes. In fact, the only requirements are that each face contain exactly four vertices, and there be a total of exactly 6 total faces.

Drawing is done in whatever is the current GL rendering context and current GL window. So you must set those prior to drawing. If you are using this with Maestro's drawing callback mechanism you need not worry about the above details. These are handled for you automatically.

Control over the vertices, color, and opacity of a box are provided. See the Box class for more info.

To draw any number of boxes, create the Box instances, add them to a Group instance then invoke the Group's draw() method.

Note that transparent boxes may not render correctly. The final polygons would need to be sorted and drawn based on the z position. This is not done and even if it were the box class is not (and cannot) be aware of any 3D objects Maestro draws diretly itself. If your Workspace can have multiple transparent objects and you need transparent boxes that always render properly, try polyhedron.MaestroCube class.
