This paper advances a means by which the conventions and methods of digital "painting" and image manipulation programs can be extended into the third dimension, providing sculpting tools that are natural and appropriate for a restricted but very useful class of models. Attempts to approximate "drawing" in 3D do not necessarily involve computer graphics Gregory71. Efforts in this area are a subject of continuing graphics research Schmandt82, Sachs89. The key to the approach undertaken in the work described here is the use of an unusual hardware technique for displaying video rasters as surfaces. With such a display, existing software for 2D graphics and image processing can be used, without modification, for creating and modifying three-dimensional surfaces. The resulting raster data can then be converted into conventional 3D databases for further processing and display. The aim of this research is to create consistent, unified methods for computer-assisted drawing, painting, modeling, and animation.
