summary |
We describe a system for procedural landform design, which uses the simple metaphor of a two-dimensional profile or Çbladeë, swept along a three-dimensional trajectory, or Çpathë, leaving behind a modeled surface in its wake. This Çpathë and Çbladeë system can mimic a common bulldozer ñ a simple rectangular blade moved along a path constrained to straight lined and large radius curves ñ as well as more fanciful landform designs ñ a blade of continually changing profile swept along an exponential spiral path, for instance. Our prototype Çbulldozerë (implemented in AutoLisp) operates in a field of procedurally defined landform Çprimitivesë to create a virtual surface, and uses a standard rectangular mesh for displaying the resultant landform. |
