Height Map Editor (open source)

[Tami]

[url=\"http://hme.sourceforge.net/\"]Height Map Editor[/url] edits, generates, and manipulates terrain height maps. These can be used in terrain renderers, which are used in games, applications, and demos. The program itself is small (the entire distribution is smaller than 400 Kb) but it can work with maps up to 10000x10000.

Features include 16 levels of zoom, the ability to sink, smooth, or rise the terrain, the ability to put your own objects (ie volcanos, rivers, mountains, craters, etc.) in/on/over existing terrain, multiple brush sizes, flood and tolerance based fills, and the ability to place a height over terrain and add to or excavate from terrain.

Features:
- Very small (the entire distribution is smaller than 400 Kb).
- Can work with HUGE maps (up to 10000x10000)
- Easy to use interface
- It is FREE, and comes with the source code, under the GPL licence.
- Multi-platform: It works on Windows and Linux, and, most likely, it would work on other OSes where SDL is available. However, so far, it won't work on big endian machines.

Things it can do:
- Generate a random terrain.
- Place a height, over the terrain (freehand lines).
- Dig (escavate) into the terrain (freehand lines).
- Add (elevate) to the terrain (freehand lines).
- Put your own objects (such as volcanos, rivers, mountains, craters, etc.) in/on/over the existing terrain.
- Multiple brush sizes.
- Flood Fill
- Tolerance based fill
- Smooth the terrain.
- Sink the terrain
- Rise the terrain
- Selection based tool, so you can affect only an area.
- Zoom in and out, 16 levels.
- Rotate, and flip/revert the terrain.
- Minimap, for ease of navigation.
- Variable grid sizes.
