Geomorph
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.
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.
