Can I import panoramas that I have already created in other stitching programs to be presented in 3DVista virtual tours?

Absolutely. No matter what program you used to create your panoramic images (spherical or cylindrical, full 360 or partial), you can import them into 3DVista Virtual Tour Suite and include them in your virtual tours. Integrate and work with your panorama just like you would do with any panorama created with 3DVista Stitcher.
