OBJ Splitting App?

[mwillis]

Hola Amigos, does anyone know of an app that will automatically split an OBJ into equal parts (either by physical size or polygon amount)?  I know of ways to go this manually but could really use something that does it automatically.

Thanks,

Mark

When acquiring complex sets of shapes, I often end up grabbing some parts in perfect focus while other parts are blurred by DOF (too close or too far from focal plane). However, I always make sure that every square inch of my project is perfectly sharp on at least a couple of photos.

Thanks Siamon but you misunderstood me.  I'm looking to chop large OBJ files into several pieces automatically.  I just thought someone may have made a program that does that.

I'm not sure about the automatic part, but I've used blender (open-source, free download at http://www.blender.org/download)  for similar projects.

I think the biggest technical challenge has to do with where, or if, your dividing plane(s) intersect the vertices of your original object. 

Here's a link that might be useful:

Best of luck

Hello Mark,

In the 1.0.0 pre-release you can enable "experimental formats" in the Advanced tab of PhotoScan Preferences window. This will add "Export tiles" option to the Export Model sub-menu, allowing to split the original model into tiles of fixed size (we recommend to reference model using scale-bars or other Ground Control data, since the size of tiles is set in meters).
It's experimental feature, but probably it will suit your needs.

Alexey, you just made my day!  Thank you!

Thanks for the link Harold.
