Abstract: Make Fractal Landscapes and Fly-Through Animations Using USGS Digital Elevation Models (DEM's)

John K. Nakata, Robert K. Mark

Photo-realistic renderings and animations were once exclusively the domain of high-end workstations. Now with the increasing sophistication of geometric algorithms, ray-traced landscapes and fly-through animations can be created on the desktop without massive CPU capability.

USGS digital elevation models are used as a framework over which fractal landscapes are placed using KPT Bryce and Scenery Animator software. End products include photo-realistic recreation of past, present, or future geologic environments and terrain "fly-throughs" that facilitate scientific "visualization". The ray-traced rendered landscapes can be presented as slides, overheads, video or printed on photographic paper while the "fly-throughs" can be viewed on the desktop or output to video.

These products are ideal for outreach and will enhance presentation of geologic data.
