The Non-Linear Video Sample (ULITEYES) demonstrates the use of non-linear video by displaying segments from a movie clip in response to input from the mouse. Whenever the mouse changes position, ULTIEYES calculates the angle of the mouse pointer to the center of the ULTIEYES video window. It then displays a frame from the movie ULTIEYES.AVI that corresponds to the position of the mouse pointer. As the mouse pointer is moved around the desk top, the eyes shown in the video window appear to follow the mouse. The movie file also contains segments of the eyes winking and blinking. ULTIEYES shows these segments when it detects a mouse button 1 click on the left side, center or right side of the video window.
