Geomorph is a height field generator and editor for the Linux 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.
Geomorph actually exists in an alpha stage, localized in French, English and German. Here are some screenshots. It is generally stable. More Info »
Its main features are, for now:
* 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.
