hey Khalid nice work! I see you have several overlapping scans from the colored images, how do you get shapefusion to merge them so seamlessly? Every time i use shapefusion (simple or poisson) i get a ridge where they overlap or where one ends, even after i "shrink" each mesh. The only way i can get no ridged seems is to trim them all so they don't overlap at all, quite time consuming... any advice?

Also, what were your Shape Fusion setting #'s for simple or poisson res, smooth, removal?
thanks.

Hi,

WoW, good result. Poisson Fusion up to value 600?
Compliments,

Hi Max,
If the scans not overlap it means You have Problems In
1- Calibration panel
2- Less No. of Scans
3- In my case my Trigger object and camera frame...If camera frame not get the trigger object at the right time , my scan will differ in Pixels..
4- I forget ;)

I have also problem in my calibration panel... My calibration grid is visible in Left side whereas the Right top side its invisible ( To check theses take one scan of calibration panel and see the calibration grid on it)... This is the reason some of my scan were not 100% overlapped However I am getting good accuracy though..

Ideally, Your scans must overlap each other..Great Number of scan will give good results..but will consume more of CPU... I did 8 scans and then merge each next scan with previous one so that my final scan overlap with the first one...

My settings were 800 Poisson and 1 Smooth...
