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 don't think so ! ViewPoint correction in PTGui is mainly designed for stitch of nadir and zenith pictures in my idea.

taf wrote:another question about the Free Nodal Point :
I make all my panorama handheld, without treepod. Is it better to select this option for all my panorama or only in few case if the detection is not good ?
AlexandreJ wrote:BTW : about one request : ability to enable that mode per image or not. We were wondering about that one too and we didn't decide if it should be done by image or globally yet. If it's just for one image, we should have a way to tell that before the detection. I don't know yet where to put that in the UI.

Would one have to place the tripod past the end of the shadow and make one shot of where the tripod was standing, so make one photo against the sun of the nadir?
AlexandreJ wrote:... This mode helps for such case. In fact, we identified 4 typical cases :
- nadir shots
HansKeesom wrote:Hi Michel, so instead of moving in the direction of the shadow, I move a meter in a direction 90 degrees on the shadow and make one shot of the nodal point. I will test it and make even two shots as there are two directions one can go for this
