Make a Panorama
360° Panorama is very useful to show tiny spaces. It's also very funny to play with and feel the space surrounding the camera.
First of all, use the Blender BGC Script to create a Cubic panorama. This wil render six images representing the faces of a cube where the camera is in the center.
Stitching images to panorama
I didn't found any open source solution for this step. So no software for Linux plateform. The solution would be to have a open source software to stitch these 6 images into an equirectangular image.
QTVR panorama can be easily played by Quicktime software but only on Mac and Windows plateforms.
Fortunately, there is a free Java panorama viewer. It's a Java applet called PTViewer. So you can show your panorama to Linux users too (and by the web if you need).
You must use a special version of PTViewer to play QTVR panorama. Here you can donwload a template with all files you need.
