Blendshape Rig

Blendshape Rig is a structure, based on blendshapes, that can generate a 3D model using a number of semantical weights, called control values. The way of the blendshapes blending is more complex than in the Blendshapes node. Using a Blendshape Rig, you can convert a 4D sequence to number of small JSON files with computed control values. Convertation is not lossless, but precise.

Use cases:

1. Wrap4D allows you to fit a Blendshape Rig to a 4D data using a FitBlendRig node. Result of the rig fitting pipeline is a JSON files with computed control values.

2. Wrap4D contains some useful nodes that can help rig creators to avoid a lot of manual work. Result of the rig modification pipeline is saved Blendshape Rig components (neutral geometry, blendshapes, relaxation masks).

Use cases expamles are described in Getting Started.
