Blender 2.5 has a new import feature that can be used for making terrain in Blender. Most terrain tutorials are about getting terrain into Blender and little if anything about getting it out. Those that are about exporting terrain are mostly for Blender 2.49. There are enough changes between 2.49 and 2.59 that it is hard to figure how to accomplish 2.49 tasks in 2.59. This article is about importing terrain to Blender and exporting for use in Second Life and OpenSim. Part 1 is about getting terrain in and Part 2 about getting terrain out.

Pixieviewer is a browser based viewer for virtual 3D environments.
It is designed to run on any device (including tablets and mobile phones) which supports modern HTML5 capable browsers like Firefox, Chrome, Safari and others.
It can either be connected to a standalone backbone called Pixiegrid as also has a (planned, in dev) connector to Opensimulator based virtual 3D worlds.
Pixieviewer directly supports 3D mesh objects created with popular tools like blender etc.
