nabbed this off the atdsk BLOG AMALGAMATION which focuses more on 3dSMax and Smoke, but I found it pretty interesting.. I've been using 123D catch for a while now, and I love it.. and combined with the new retopo in 2014 it makes it super useful for building assets..
if you are havn't been using 123DCatch, I definitely recommend checking it out.
here is a bunny sculpture I captured and then used FBX into maya.
in any case... here is the info from the ATDSK blog
In this video, I show the basic concepts behind the workflow and interop of Autodesk Catch123D, 3ds Max and Mudbox. Highlights include the FREE creation of high resolution, textured models using photogrammetry techniques in Autodesk Catch123D (3D models from real-world photography).
The resulting, high resolution, triangulated mesh is cleaned up in 3ds Max and then, using the one-click interop between 3ds Max and Mudbox, a live link is created and the models is passed off to Mudbox.
Using the new Retopology feature of Mudbox 2014, a cleaner, quad mesh is generated with lower levels of detail, a normal map is extracted from the original high resolution mesh, and the final result is passed back to 3ds Max for use in tasks like rigging, lighting rendering or exporting to a game engine.
