360 software for non-360 camera

[tribal-warrior]

Fairly soon, I'm going to shoot a 360 degree panorama of a room interior with an M4/3 camera and 12mm lens, as well as getting shots of the ceiling and floor. So basically 360 horizontally and 180 vertically. Can anyone recommend some freeware for stitching and creating a virtual panorama out of the individual shots taken with a wide angle lens? Evidently, some panorama stitching software will have problems with the distortion from wide angle lenses but I believe the ones designed to create virtual tours seem to handle wide angle / fisheye images just fine.

I wanna create one of those interactive panoramas where you can choose to pan around or tilt up and down with the click of a mouse. With regards to shooting, I admit I don't have anything fancy like a Nodal Ninja (just have a cheap, basic slider that should rotate the lens on it's nodal point horizontally) so I'll probably have to do the vertical ground and ceiling shots hand held. As such, the results will probably be very rough but I'm just experimenting at this stage.

Here's an example of the sort of interactive imagery I want to create.

I use open source Hugin software for stitching 360 deg panoramas. Look http://hugin.sourceforge.net/
Good free HTML5 player to show your panoramas is Marzipano: http://www.marzipano.net/
First I stitch several individual photos to one equirectangular photo. Often I take 35 shoots with 24mm lens, sometimes I use circular FE and take only 4 shots.
Hugin can handle geometric distortions well. The biggest computer work I do with Hugin to make good stitch.
When I have the equirectangular image made, I put it into Marzipano tool and there you are! Or almost. Often I edit index.js, data.js and style.css files in Dreamviewer later.
