  org.j3d.loaders.c3d.C3DTrajectoryData

public class C3DTrajectoryData
extends java.lang.Object

The representation of a single trajectory.

A trajectory may contain coordinate and/or analog data samples. Coordinates are expressed in 3D space in X,Y,Z orientation. All values are placed as their real floating point representations. If the underlying file had values in integer format, scaling will be performed before storing in this array.

The definition of the file format can be found at: http://www.c3d.org/

Field Detail

label

public final java.lang.String label

The name or label associated with this trajectory data

description

public final java.lang.String description

The description string associated with this data

coordinates

public float[] coordinates

3D coordinate data for this frame. Values are interleaved as [x1,y1,z1,x2,y2,z2....].

numFrames

public int numFrames

The number of valid frames of coordinate data

cameraMasks

public short[] cameraMasks

The bit mask of camera IDs that contributed to each frame. Using a short rather than a byte defined by the C3D spec as there are proposals to support more than 7 cameras proposed by Vicon.

residuals

public float[] residuals

Accuracy information about the coordinates made each frame.
