I searched all source code files of Hugin++ for the string "tilt" (e.g. there could be variables tilt_x, tilt_y, tilt_z like in libpano13). But there wasn't found anything. So Hugin probably does not use tilt.
I don't know the meaning of it. But I wouldn't delete the tilt from libpano13. Hugin and libpano are widely used software, and surely some people have made other tools that can be used with libpano13 and Hugin. If there are no ** very good ** reasons against it, you should keep backward compatibility when developing Hugin++ and libpano13 / fastPTOptimizer further. [email protected] schrieb am Mittwoch, 10.
