Keywords: Alliant ; How did they do it? Message-ID: <26@airgun.UUCP> Date: 12 Jul 89 22:41:46 GMT Distribution: na Organization: Western Geophysical, Houston Lines: 25 In their advertisement in the July 89 issue of Supercomputing Review (pages 6-7) Alliant features 4 images showing "typical" applications. The one on the right, captioned "Mission Planning" shows an image of a landscape, with valley, river, and mountains. It has something of a fractal character to it. My questions are: 1. Is this image just a fractal landscape, or does the image represent a "reconstruction" of a real-world location based on data points with elevation, etc. 2. If the latter, how is the real landscape modeled? As contour lines or discrete points (or a grid)? The detailing of the mountain (in particular) seems to imply either a very high level of detail for the model or some degree of fractal "interpolating" to add texture to the landscape. 3. Assuming it is not just a fractal image, is this an application some one markets? As usual, thanks in advance.
