Welcome to the Geomorph site

The Geomorph site gathers all guides and tutoriels written since the 0.11 release, in 2003.

If it's your first encounter with Geomorph, do not forget to read the introduction, which explains among other things how are generated the height fields.

See also the guides and tutorials list in the documentation index.

And last but not least, do not miss the gallery!

Fixing a crash related to the continuous pen (March the 17th, 2007)

Trying to modify the size scale or the level scale, in the continuous pen

, produces a crash (segmentation fault) on some systems. The bug was detected on an x64 system, but it can happen on any system.

Version 0.41 will fix this, in a few days, along with a few minor problems.

Meanwhile, it can be fixed by replacing "draw_dialog.c" before compiling the 0.40 package with this file:

http://geomorph.sourceforge.net/misc/draw_dialog.c

After downloading the file, open a console and copy it in your Geomorph source tree:

cp draw_dialog.c ~/geomorph-0.40/src/hf/draw_dialog.c

Best thanks to Sanne for submitting the bug and testing my solutions!

The 0.40 version is here, finally! (February the 21st, 2007)

After more than one year, here is Geomorph 0.40, at last. It provides some important new features, a lot of small improvements and fixes, plus a richer documentation.

Here are the main new features:

A crack network creation tool, mainly inspired from the article Image-Guided Fracture from David Mould.
A tool for raising the edges of flat surfaces.
A tool which increases the noise on the height field. This is the equivalent of the "sharpen" tool in a paint program.
New Povray scripts are provided for taking advantage of these tools. See the scripts index.

The new crack network tool can be used to create "normal maps" which can be tiled infinitely

Geomorph is not a program which can be used as intuitively as a word processor. Tutorials and guides are generally required. This version provides some new or updated documentation:

A page about how to use the "water maps", which contains links to three short tutorials.
A guide about the use of the crack network tool and the Povray script index already quoted.
A "Getting started" page which has been largely updated and which describes, among other things, the different subidivision techniques used in Geomorph pour créer un terrain.
An updated tools index.
A FAQ and a downloading / installing .

New tutorials and new Povray scripts feature the use of "water maps".

Finally, a lot of fixes and improvements have been made, including many when preparing the tutorials. Here are some of them :

The rain erosion algorithm has been improved a lot. Some explanations are given in the tools index.
Configuration scripts have been updated to allow compilation under x64 CPUs and some recent distributions (thanks to Andy Pfiffer).
In the "wave" tool , the randomisation parameter does not create discontinuities anymore.
The reliability of the automatic committing mechanism, when switching between different dialogs or different windows, has been improved.
About the document window:

the (x,y) position and the altitude under the mouse cursor are not always displayed in the top left corner, not only when a pen is used;
after a zoom in, the height field is now centered in the window.

Messages and dialogs have been translated to German by Simon Donike, like for the most recent versions.

See you later, during the next year, I hope!
