Civil war field artillery

I have been playing with 123d Catch and am somewhat intrigued by its possibilities. This started with a large set of photos of a 2 to 3 inch brass cannon model. I then exported an OBJ from 123D Catch and imported it into SU which almost choked on the file size. Then I applied some styles and composed my shot. From there I took it to PhotoShop to dust it with a little moodiness. Lastly I used FotoSketcher to add more textures and and profile lines.
Lessons learned:
- Always use flat light when making your photo sets.
- Go for 40 to 70 photos.
- Avoid deep shadows.
- Use single focal length prime lenses.
- Keep distance from camera to cent of object as close to the same as possible unless you want to do a lot of tedious manual photo stitching.
- 123 can be used in a very impressionistic manner and under certain conditions it can be used for photogrametry.
- It reveals its capabilities slowly

Out of interest Rodger what was the file size? And did you consider using mesh lab to reduce the size?

The model started out with 359,000 edges. I tried using the simplify tool in Artisan and it processed about 1/3rd of the file before choking. Meshlab crashes as soon as I try to open the file.
I should have processed the file for mobile phone resolution right from the beginning to start with a smaller file.
What I have been doing is identifying key points of the model and ripping out overly complex mesh and replacing it with flat surfaces.
