We have downloaded Ipix demo version and tested it ourselves.
The most important advantages of Panoweaver 4.0 compared to Ipix include:
1)Panoweaver 4.0 takes less time than the software of Ipix to stitch fisheye images. For example, on a Pentium III computer, Ipix software takes about half an hour to stitch a set of 4 fisheye images. I started the stitching in IPIX before going for lunch. When I came back after 20 min, ipix only reached 80% percent and was still working on the image. While with Panoweaver 4.0, it takes only two or three minutes.
2)According to our test, Ipix produces an unsatisfactory panorama after taking a long time stitching process. While Panoweaver process a fully auto stitching with high precision. There is no mismatch. With Panoweaver 4.0 you can get a nearly perfect stitching result than Ipix software.
3)Panoweaver 4.0 can stitch 4+celing/floor and 6+ceiling/floor fisheye images. You only need to shoot two fisheye image up and down. Panoweaver will produce a pano with seamless sky and floor.
One thing I can assure you is that your waiting for Panoweaver 4.0 will be worthwhile. It will be presented to you for evaluation in March, 2005. By then you'll know I am not overstating our products. :)
