The table has a wood texture applied to it. The teapot has a checkerboard pattern with an alpha component so that it is possible to see through it when textures are enabled. The other objects in the scene were created using OpenGL , GLU, or GLUT calls. There is no real ceiling, but the user is not allowed to go beyond or above the walls or floor. In addition to the commands listed above, the user may toggle the lighting and shading models via the menu.
Any messages go to either stderr or stdout.
This toolkit is basically a replacement for the AUX library described in the OpenGL Programming Guide . It provides API calls to open windows, handle window events, create menus and interface to devices such as mice, keyboards, and the spaceball. This is a simple 3D modeler available for the SGI . It can export Inventor and VRML files as well as IRIS GL and OpenGL data files.
