The planetarium of the Weber State University uses Blender to create content for their full-dome digital projector. Rendering for this screen requires a Fisheye camera, for which they have created and released a camera rig.

The Ott Planetarium is pleased to announce revision 9a of our Blender Fisheye Camera Rig. Previous revisions have been available on our website — but we’re making noise about it this time because we’ve finally fixed the render preview!
Our rig makes fulldome-ready images, complete with a working fisheye preview. This method requires no additional software or scripting, and renders in a single step with the internal render engine.
We are releasing the rig under the Creative Commons Attribution-Share Alike License.
