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. Unlike the Blendshapes node, the the blending process in a Blendshape Ris is more complex. With a Blendshape Rig, you can convert a 4D sequence to number of small JSON files with computed control values. While this conversion is not entirely lossless, it achieves high precision.

Use cases:

1. 4D Data Fitting:

Wrap4D allows fitting a Blendshape Rig to 4D data using the FitBlendRig node. The result of the rig fitting pipeline is a JSON file with computed control values.

2. Rig Modification:

Wrap4D has useful nodes to simplify rig creation, reducing manual work. The result of the rig modification pipeline is saved Blendshape Rig components (neutral geometry, blendshapes, relaxation masks).
