When tasked with the development of a space-based visual data base on a non Z-buffer type image generator, engineers at McDonnell Douglas Helicopter Company encountered several problems. These problems included polygon distribution, curved surface shading, texturing, and allotment of moving models. As always, a finite number of polygons was available per visual scene. Judicious use of these polygons was employed at every stage of development, the intent being to provide the most accurate scene content possible. Trade-offs between curved surface shading and texturing were examined, and made when deemed appropriate. Last, but certainly not least, the number and complexity of moving models would play an important role in the development of the McDonnell Douglas Helicopter Company Visual System Analysis and Demonstration data base.
