Interactive Techniques for 3-D Shaded Graphics

Conference paper

Abstract

Interaction with 3-D shaded graphics has become feasible by-incorporating local hidden surface removal and visible surface shading capabilities in the raster display system. The Lexidata SOLIDVIEW system not only reduces the response time from minutes to seconds, it also provides powerful 3-D interactive techniques. This paper will describe some of these techniques:
  1. 1.

    3-D Cursor

     
  2. 2.

    Sectioning

     
  3. 3.

    Surface Picking

     
  4. 4.

    Translucency

     
  5. 5.

    Contouring

     
  6. 6.

    Light Source Manipulation

     

These added capabilities coupled with traditional graphic techniques will greatly affect the man-machine interface of the next generation graphic systems.

By the end of the decade, their use will be widespread in such applications as 3-D medical and geophysical data interpretation, CAD/CAM, animation, technical illustration, architecture, and molecular modeling.
