BSUNCUBE(6)                      Games Manual                      BSUNCUBE(6)



NAME
       bsuncube - view 3-D Sun logo

SYNOPSIS
       /usr/demo/bsuncube

DESCRIPTION
       bsuncube  allows  the  user  to view a cube from various positions with
       hidden faces removed.  The faces of the cube consist of the  Sun  logo.
       The  viewing  position  is selected using the mouse.  Using the SunCore
       Graphics Package, a 3-D projection is drawn on the Sun Monochrome  Bit-
       map Display.

       The  program  operates  in two modes: DisplayObject mode and SelectView
       mode.  The program starts in DisplayObject mode:

              DisplayObject: The cube is displayed  in  3-D  perspective  with
              hidden  faces  removed.   Type  q while in this mode to exit the
              program.  Press RIGHT mouse button to switch to SelectView mode.

              SelectView: Schematic projections of the outline of the cube are
              shown  and  the mouse is used to select a viewing position.  Use
              LEFT mouse button to set x and MIDDLE mouse button to set  y  in
              the  Front  View.   Use  MIDDLE mouse button to set z in the Top
              View.  Press RIGHT mouse button to switch to DisplayObject mode.

       The view shown in DisplayObject mode is  drawn  using  the  conventions
       that  the viewer is always looking from the viewing position toward the
       center of the cube and that the positive y axis on the  screen  is  the
       projection of the positive y axis in 3-D cube coordinates.
