Re: [rp-ml] low-res 3D scanning

Dear All, Dear Ian,
we have the same experience with two scanners from Creaform, the law
resolution one which is more than acceptable for the visualisation (the
resulition can be adapted, and when you speak about the resolution, I
suppose that this is the resolution of the scanned model). We are very
happy about this and we use it connected to a very large screen in an
immersive virtual reality room.
Of course, the second sensor, the high-resolution and color one is of
course better... but also more expensive...
So, I agree with Andrew. The ViuScan should be perfect.
Best Regards,
Alain
