Scope 4D displays 3D animations that gyrate to the rhythm of your sound card. Scope 4D scans the music coming from your soundcard. It analyzes the rhythm to create a real-time 3D-animation that moves to the beat of the music. The animation can be displayed in a window or full-screen. Depending on the type of graphics adapter you have, you may also be able to display the animation on top of other applications in a special "overlay mode". You can use the 3D objects and backgrounds that come with Scope 4D, or customize things by replacing them with your favorite BMP or JPG image files or X drawing files. (.X is a Microsoft format supported by CAD programs such as AutoCAD).
