Terra

A heightfield application, temporary called Terra.

I like landscape scenes rendered with Povray. Often i'm trying to find a proper location for the camera in the scene. Or I want to do some modifications on the heightfields etc.
I'm going to write this Linux application to make these jobs more comfortable, another purpose is to enhance my skills on programming graphical user interfaces in C using GTK+.

Later I will implement functions of The Genesis Toolkit combined with the advantages of a graphical user interface, for example object placement, heightfield merge operations etc.

Currently it is still in an early stage of development. Suggestions are welcome, just send me a mail. Maybe you want to beta test?


2004-11-14: To enhance the height field display I need a better height to color function. To solve this i started another project, a Pov-Ray color_map editor. Later i will reuse the functions to implement them in Terra.

2004-12-05: The color map editor has been develloped quite far and most functions work now.
I initially havn't planned to write a colormap editor as standalone application because you can edit colormaps with the Gimp. But i think this little tool could be usefull for others too. If you like to beta test you can download it here: gpovcolmap-0.00.04-beta.tar.gz
Currently you can edit colors and colormaps. Export the colormap to stdout by pressing the Map-button. You can't import colormaps nor load or save them.
The decision whether to proceed with development of this colormap editor is made upon the question if there are enough people who are interested in it. So if you think you may need it send me mail.
