This program uses a fast texture mapping algorithm to get QuickTime movies and Video-In onto a cube. The video source is displayed on the 6 faces of the cube in real-time while performing rotatation. There are two versions of this program: a 68k version and a PowerPC™ version. This program demonstrates the Power Macintosh's awesome ability to perform real-time texture mapping while transforming 3D geometry. (The 68k version of the program is included for performance comparisons).
Here are some notes on this demo:
• for best results set your monitor to 16-bits per pixel
• use the mouse button to rotate the cube to a desired viewing angle
• use the mouse button in combination with command for x axis rotation
• use the mouse button in combination with option for y axis rotation
• use the mouse button in combination with control for z axis rotation
• use the "Open" option to load and play a QuickTime movie from disk
• if there is a video digitizer present then choose the Play Video In to get video-in on the cube faces
• the "Commands" menu allows for auto rotation of the cube
• the "Commands" menu allows the user to switch between displaying the movie or video-in
• use "Video Settings" to change the video digitizer parameters
• the "Commands" menu allows for square pixels
• the "Commands" menu contains a "Loop" option which can be used to play the QuickTime movie forever
• the "Front" option returns the cube to the front face position
• the "Spin Around" option rotates the cube in an interesting manner with a little more constraint than the auto rotate option
• try "Bug Eye Mode" just for fun
• the "Sound" menu allows for control of sound volume; turn sound off for higher frame rates
