Description

Assumes all selected nodes are intended to be rigidly connected; selects any keys on those nodes that stray outside the given rigidity tolerance.

The findNonRigid command is useful for screening out the effects that an errant object motion within a group assumed to be rigid will have on a rigid body applied to those objects.

As a result of digital noise, occlusions, or marker collisions objects that ought to be rigid sometimes display non-rigid behavior; findNonRigid allows you to identify such keys with a tolerance value expressed in millimeters. After identification, you can choose to process or ignore any keys that are found to be non-rigid.

// Executing these commands will have the effect of selecting all keys
// within the specified left foot markers that are more than 20
// millimeters distant from their rigid location.
// The rigid location for each marker at each frame is that location
// defined by the provisional application of the rigid body.
