Compositing DISSPLA Output with Synthetic Images ISSCO Week 86

摘要

A number of graphics packages exist at Sandia to provide scientists and engineers a means of efficiently representing their data. These packages include DISSPLA, TELL-A-GRAF, Mapper, Movie.BYU, Weasel, and some state of the art scene software currently under development. Some very enhanced graphics can be obtained by combining the output of some of these graphics packages. This presentation will discuss a method that was developed which allows incorporating the output of DISSPLA, the most widely used graphics package at Sandia for representing scientific data, with the scene software. The result of this combination is a high quality very informative graph. The procedures that are used to perform this combination will be discussed and many examples of the resulting output will be presented. The technique can be used for simply adding annotation to an image generated using the scene software or to add an attractive background from the scene software to a text slide made using DISSPLA. This technique can also be used to merge a ray-traced 3-D surface with a corresponding 3-D DISSPLA vector plot. This is how the two graphs from Sandia on the 1985 ISSCO poster for the ''Battle of the Artists'' were made. (ERA citation 11:018952)
