Yes, I too would like to see the finished result from 3DVista using those images you posted for download.
Phoenix, I don't believe you can do a 360x180 panorama with only 4 shots from a 300D or 10D camera with a Sigma 8mm lens. But I would love you to prove me wrong.
You can see the 3D Vista pano at www.garykmeyer.com/3D Pano.jpg
And if you want to see the original 3 hemishpere images, you can see them at
Any help you can offer would be appreciated.
Although you have had marginal success with 3DVista stitching these images you have supplied for download. You simply will not have a successful 360x180 spherical panorama until such time as you position your camera on your tripod correctly. The nodal point is most critical when using Panoweaver or 3DVista software. I stitched your images with both these programs and got very similar results. I then manually stitched them and the result were much better but are never going to produce a 360x180.
By simply finding the nodal point of your camera & lens set up you will be well on your way of getting major success from panoweaver and 3Dvista.
OK, I must admit I'm basing all of my comments on the fact that the Canon 1Ds and Sigma 8mm Fisheye lens can in fact produce a set images that can be stitched with Panoweaver. This I base on what Easypano have stated on the website. As I have never been sent a set of images taken with this combination before and I'm not rich enough to go out and buy this set up without first knowing that it is 100% successful combination.
The nodal point can be tricky to find. But I know from personal experience that that the nodal point is pretty much in line with the gold ring near the face of the Sigma lens using a Canon 10D Sigma lens combination.
Hope this helps, Smooth
