Re: High resolution ROI in panorama
- Wow Jim that's a really nice job!
I have wished MANY times for an EASY tool to insert high-rez shots into a spherical fisheye pano. There really is no easy way that I know of.
I remember Aldo showing this off with Spi-V back in 2006 in Bath at the Panotools meeting....
I wonder if a GUI for Krpano could be made for doing this, as part of a tour builder?
