According to Wikipedia Animation Master is:

Text Box

Animation:Master is a 3D character animation application offered by Hash, Inc. that includes tools for modeling, rigging, animating, texturing, lighting and rendering. Although Animation:Master was developed for and is targeted towards independent artists, with a workflow optimized to enable one artist to create a rendered animated piece from start to finish, the workflow also presents economic advantages for larger workgroups.

The software uses a proprietary spline mesh technology to perform modeling and animation, and it is different in this sense frompolygon mesh or NURBS-based programs. The system used is called patch-based modeling. It uses multiple intersecting splines to create surfaces, called patches. Patches present an efficiency in that one patch can describe a complex curved surface that would require many facets to approximate in flat polygons.

Aside from the typical 4-sided patches common in many spline modeling environments, Animation:Master can also create 3 and 5-sided patches which enable mesh topologies not possible in other applications.

If you hover on the ANIMATION MASTER in the main menu, you will get a dropdown to work through the various tutorial sections.  You should work from beginning!  But DO ENJOY!
