NAME

robot − control a robot arm

SYNOPSIS

/usr/people/demos/robot

DESCRIPTION

Robot displays a model of an imaginary robot arm.  Operator controls adjust the viewing parameters, the articulation of the arm, and the illumination. 

Most user interface is through the mouse and its buttons.  Press some combination of buttons and move the mouse to alter the display.  The functions selected are displayed on the lower edge of the screen. 

In the default case, the simulated object is lit as by a point source behind the viewpoint.  Type S to simulate light from an arbitrary distant point source.  Hold down MIDDLEMOUSE and RIGHTMOUSE and move the mouse to alter the altitude and azimuth of the light source.  Other combinations of buttons still allow viewpoint modification and articulation of the object.  Type s to return to normal illumination. 

DISPLAY OPTIONS

Upon entry into the program, robot is set for NTSC or high-resolution output, depending on the currently selected monitor.
