Are there any programs for converting 3pt polys into 4 pt?
I'm considering getting a scanner but the scans all output polygons as 3pt I believe.
Looking for laziest solution.

The laziest solution I know would be Anthony Appleyard's Detriang - but you have to expect a lot of oddly-shaped quads in its output compared to a manual approach.

Wings 3D includes a de-triangulate function with 3 different strengths of the algorithm to choose from. It does a pretty good job.

I think Blender has a Tris to Quads function somewhere

Yep, Wings does a good job at this.

Well I always did like the Wings interface.
Thanks everyone for the advise.

Hey I'm in good company! I prefer the wings interface over that of say hexagon for example myself!
For a good while now, thought I was the only one who did. Nice to know I'm not all alone. :lol:

tris to quads works best when its repairing a mesh that was either exported as 3ds (all tris) or tripled. Its a good way to get huge numbers of non-planar quads or odd shaped quads which Poser in particular hates.

Granted, but that's depend of what software/algo you are using. an efficient "untriangulate" or a basic "tri-to-quad" conversion.
