Geomorph alternatives
Geomorph is a free, open-source software application for Linux designed to create and modify height fields, which represent three-dimensional landscapes as two-dimensional projections. The program facilitates the generation of square images, providing a three-dimensional preview and enabling subsequent rendering through tools like Povray. It offers a range of editing tools, including fractal drawing, erosion simulation, and image manipulation capabilities, alongside a robust undo/redo system.
