Building an interactive 3D animation system

Abstract

The continued improvement and proliferation of graphics hardware for workstations and personal computers has brought increasing prominence to a newer style of software application program. This style relies on fast, high quality graphics displays coupled with expressive input devices to achieve real-time animation and direct-manipulation interaction metaphors. Such applications impose a rather different conceptual approach, on both the user and the programmer, than more traditional software. The application program can be thought of increasingly as a virtual machine, with a tangible two or three dimensional appearance, behavior and tactile response. Dynamic graphics techniques are now considered essential for making computers easier to use, and interactive and graphical interfaces that allow the presentation and the direct manipulation of information in a pictorial form is now an important part of most of modern graphics software tools
