* Free Nodal Point ability (quite the same as viewpoint correction in PtGui ). This feature is for Autopano Giga only.
I have had to upgrade from APP to AGP and be able to use this new feature.
I am quite familiar with the PTGui viewpoint correction and I am using it mostly to insert an oblique nadir view (hand held or not): this image is unobstructed by the panohead/tripod and allows by the same token to remove the ugly shadows of the tripod legs. AFAIK this is by far the most frequent use of the PtGui function and it's truly efficient as long as the "floor" of the panorama is flat enough. I must confess that I could not yet figure how to do the same achievement with the new "Free Nodal Point ability". With APG 2.5.0 A1 the result is a mess, so I beg to be told how can we select e.g. the oblique nadir shot to be solely affected by the "correction" (and letting all the other images be driven by standard "Nodal Point" restriction)?
It's also possible to use the ViewPoint correction of PTGui for other purposes (including what you, Alexandre, tell us about in the video) and automatic control point creation by PTGui works also fairly well in those cases.
When we decided to add Free Nodal Point Ability to our engine, we wanted it to be automatic. Normally when doing that, you cannot rely on automatically created control points. You need to enter them manually. Again, we think that an automatic solution that works should be created first. If it solves 90% of the cases, it's good. This is our goal which is why we have the new ransac stage 'full 3d'.
I loudly applaud your bet on CP creation automatism. But I believe that oblique nadir patching wont work if other automatisms can't be overridden e.g. to allow "correction" of only selected view(s). Automatic CP creation should IMO not be incompatible with "image selectable" Free Nodal Point ability.
With the current APG 2.5.0 A1 version, the assertion " Free Nodal Point ability is quite the same as viewpoint correction in PtGui" is debatable. Or did I miss something?
