Requirements

VS/VSE 3.1.2 for Win32s on Windows NT or Windows 95 with OpenGL dlls installed. A color display setting exceeding 256 colors should be used.

OpenGL3DViewer new open

The OpenGL3DViewer has sample views that may be opened from the menu bar by selecting OpenGL and then one of the three example items. Each of these example views are defined by a class in the installation. Inspect the classes Face, Maze, and Cube to see how the example surfaces are defined. The following key combinations will shift the view in the OpenGL Window:

        Up arrow key: move forward
        Down arrow key: move backward
        Left arrow key: move left
        Right arrow key: move right
        Page Up key: move up
        Page Down: move down

        Ctrl + Up arrow key: look up
        Ctrl + Down arrow key: look down
        Ctrl + Left arrow key: look left
        Ctrl + Right arrow key: look right
        Ctrl + Page Up key: rotate clockwise
        Ctrl + Page Down: rotate counterclockwise
