operating system. A height field is a kind of topographic map. It is a 2D projection of a 3D landscape. Geomorph generates square images and shows a 3D preview of the resulting landscape. The resulting 2D image can be processed with a tool like Povray for rendering the landscape. WWW: http://geomorph.sourceforge.net/ PR: ports/94521 Submitted by: Dmitry Marakasov <amdmi3@mail.ru>
