The Editable Terrain Manager is an addon library for OGRE which manages and displays terrain based on heightmap data. It can be used as a replacement for the Terrain Scene Manager, but its main advantage is the edit possibility for the terrain: You can deform and set the terrain heights in real time, as you would need to if you are developing an editor application. In addition, the library also has means to support editable splatting, probably the current standard for detailed terrain texturing.

All of the parts have been designed to be as flexible as possible and do not even depend upon each other. That means you don’t need to use splatting if you don’t want to - or you can use that part with a different terrain renderer. Unlike OGRE’s TSM, it’s not a scene manager, either, so you could (in theory) choose whatever scene manager you like. All its headers are light-weight, using the PIMPL idiom to hide costly implementation details.

Due to a server move the address for the SVN repository has changed. Note, however, that the repository contains the defunct ETL development version, which is no longer being updated. I merely kept the repository alive for those who are already using ETL and might need the code. Anyone else, please use the new Terrain component in Ogre svn!
