Blender Low Poly from 123D Catch

A test to see how easy it is to create a real-time low poly asset from a high poly 123D Catch mesh.

Took 40-50 photographs of a stone sculpture I did a few years back.
Took these into 123D Catch and generated a high poly mesh (400k tri polys).
Imported into Meshlab and reduced it down to 250 tri polys using Quadratic edge collapse.
Imported both the high poly and low poly meshes into blender.
Cleaned up a bit and then unwrapped the low poly.
Baked the normal and texture from the high poly onto the low poly in Blender @ 512x512.
And finally rendered both high poly and low poly in Blender using the OpenGl viewport.

Quite quick really to do. The uvmap can be done very quickly as it is all baked and therefore a bit of stretching or odd orientations do not really matter, just slap in a few texture seems and auto unwrap, et voila.

@Killadey Sorry, i figured it out ;)

Sorry to use you as a free technical consultant, but could you advise me on how to import the model into blender textured? From 123d I export as .obj. Im then left with the .obj and a .mtl file, how would i use the material file to get the texture in blender?

Thanks, and well done on your attemp!
