Possible improvements about fspy HOT 4 OPEN

Hi William, thanks for your feedback! It would be interesting to have a look at some of the problematic images (both old and new ones) to better understand what issues you're seeing.

Hello ! Thanks for this great and free tool.
I second the request for a scroll zoom if you ever feel like working on fSpy again.
It would help to visually check the lines instead of the dots only.
Sometimes i'd like to "blindly" place a point and control with the line but it's actually not easy.
Cheers

Hi there, sincere apologies for an incredibly delayed reply, I didn't know I had gotten a response, spam folders, we love and loath them.

I will post some images, mainly older ones as they are the medium most worked. Most are neatives digitalised in a single image, incase stiched photos are a problem. The modern images may shed some light on the issues, some parts of the buildings aren't perfectly straight being plaster finished by hand. The house in the back of the older one is the most interest at the moment as plans have already been sourced, at the time these dwellings were only 30 years old and had not suffered subsidence or movement.

Another suggestion would possibly be being able to pin the Box to any of its corners and increase lines on it in an attempt to stighten the match.

Cheers

I just had a quick look and the images you posted seem a bit tricky to work with when using two vanishing points. However, all three images have a discernable third vanishing point and I got (what appears to be) decent results using all three vanishing points. Have you tried that?
