Struct Binary.TrajectoryFragment

A trajectory fragment contains information necessary to perform similarity calculations between trajectories.

Namespace: Unity.Kinematica

Assembly: solution.dll

Syntax

public struct Binary.TrajectoryFragment

Remarks

A trajectory is simply a sequence for root joint transforms forming a continuous path. Trajectories can either be expressed in world space according to the original animation data or relative to a sampling time.

A trajectory fragment can be constructed from any animation pose contained in the motion library. It requires a metric in order to extract the relevant information. The similarity calculation uses a weighted sum of features that includes root velocity, forward direction and optionally root displacements.

The main purpose of this class is to: * Create trajectory fragments from poses in the motion library. * Perform similarity calculation between trajectory fragments.
