The equivalent QTVR is OK. > :-P That's not a bug; it's a feature! Really. The 0.61 update defaults to the panocylinder for non-cubic images, so that you won't have to switch to make Pannini views. So if you want to view full spherical images, you now have to switch back to the panosphere. (Well, nothing is perfect.) Future releases may do yaw and pitch before painting the panosurface, which would let you see zenith and nadir (when available) on the cylinder too. I've been experimenting with Mathmap, trying to replicate Panini's projections (using your "erect_erect.mm" to set the view direction; thanks) and it is stimulating several ideas about better generalized Pannini projections. Command line Mathmap looks like an ideal "back end" to render Panini views at source resolution. Or maybe Panini could become a "front end" for Mathmap, which is clearly the more capable program. My goal is an interactive system that can "tweak" the basic Pannini projection to render a given view perfectly -- just as the vedutisti did.

Hi Tom, 0.61.79M gives me a "black hole" at the zenith and nadir when displaying equirectangulars. The equivalent QTVR is OK. Best wishes Peter.

For the record, I don't have a Mac (I only wish I had one, haha). I'm running WinXP SP3 and just updated my graphic card drivers (ATI Radeon 9600SE) to the newest version. I just installed the drivers, not that piece of memory consuming bloatware called Catalyst. > I wouldn't have > any idea how to set up mapping of multiple texture images onto one > surface. If you do know, please tell me. Well, basically they're just 6 rectangular projections 90 degrees apart, which shouldn't be too difficult to backproject onto the panosphere. I guess you're already doing the same thing when loading a rectangular image? > Am I safe in assuming that you can display the non-cubic formats OK? Correct.

Me neither, unfortunately. I've read through the source code a bit and couldn't find anything wrong there. Moreover, I compared your code to some of the code available on other websites (by googling), and if not pretty much an exact copy, it's still fairly the same amount and order of operations. Strange. If you look closer at the picture I linked to in my previous post, it's not only that the same image is shown on every face. It's shown with a *different* error on every face. The images are shifted in both X and Y directions (in texture coordinates), and have border issues which differ from face to face. It popped into my mind that something might be wrong with texture coordinate generation internally, but this does not quite explain the cloning behavior. By the way this is the first time I dive into OpenGL, so don't expect me doing wonders just yet ;) Cheers, Bart --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "hugin and other free panoramic software" group.

Any help you can give would be most welcome. I am not a Mac developer and have no Mac to test on. At this point I have no idea what is wrong. Some other problems that have been reported: -- defective areas shaped like parts of the edges of the cube -- failed cubic loads with error messages and/or black display -- cancelling a cubic load at the fileselector makes subsequent loads fail (this has got to be my fault, but it only has been seen on a Mac).

Hi Tom, Thanks for bringing regular updates! Unfortunately, I still have issues displaying the example cubic panoramas. Loading from JPGs and QTVR gives different errors on screen though. It might be the OpenGL implementation on my machine, although I doubt that, because I've never seen such errors in other applications using OpenGL. Here's an image showing 4 screenshots: both QTVR and cube faces, both with initial view and super fish at 260 degrees FoV. http://lh3.ggpht.com/_Fel5i-Q8T8g/SWXolMtRS5I/BxA/i78G0TsTEw4/2009.01.08%20Panini%20cubic%20pano%20errors.jpg As you can see, the same face image is shown on every cube face, although with slightly different displaying errors. I assume you are still using OpenGL's builtin solution for the cube thing? I guess this one causes the trouble. I'll see if I can figure out more details later.
