Geomorph is a height field generator and editor for Linux.
It features tools for generating height fields from subdivision and surface addition algorithms, with fine control of frequencies, output to 16-bit PNG files from 128x128 to 4096x4096 pixels, a pen for drawing height fields chunks or craters, and tools for eroding, stratifying, and smoothing the height fields.
Geomorph offers a multiple window environment with OpenGL preview, undo and redo functions, and basic controls for Povray rendering. English, French, and German localizations are included along with English and French tutorials.
Here are some key features of "Geomorph":
· An environment allowing multiple documents in multiple windows.
· Output in PNG files with 16 bits per channel, from 128x128 to 4096x4096 pixels, giving 65536 levels from black to white.
· Tools to generate height fields by simple subdivision or repeated sum of an arbitrary surface.
· A fractal pen for drawing irregular surfaces.
· Pens for drawing smooth strokes, craters, faults, cracks and fissures.
· Edit and transform tools appropriate to image editing - brightness/contrast and the like (few "paint" programs can edit 16 bits per channel images).
· Edit and transform tools relevant to height field editing - erosion, quantization ("terraces"), cityscapes, and the like.
· A Povray run button, for testing the current image with a scene you select.
· An undo/redo history, with multiple levels. The default history stacks has 5 levels, but this parameter can be adjusted in the configuration file.
· A display scale control.
· An OpenGL preview (MesaGL).
· A tool for editing configuration files, where default directories and other parameters are saved.
What's New in This Release:
· This release provides a new integrated interface, a new "Fourier Explorer" dialog for playing with the Fourier transform over height fields, interface improvements, bugfixes, and new documentation pages.
· It has also been adapted for the x64 platform.
