Field Detail

bindMatrix

public final org.openmali.vecmath2.Matrix4f bindMatrix

The bind matrix

invBindMatrix

public final org.openmali.vecmath2.Matrix4f invBindMatrix

The inverse bind matrix

relativeRotation

public final org.openmali.vecmath2.Quaternion4f relativeRotation

The rotation of this bone

relativeScaling

public final org.openmali.vecmath2.Tuple3f relativeScaling

The scaling of this bone, along the three axis : X, Y, and Z.

rotKeyFrames

public java.util.ArrayList<KeyFrameQuat4f> rotKeyFrames

Temporal key frames for the bone. They are reference extracted from the current animation and they will change every time you play a different animation. They are here to simplify the animation algorithm. These are ROTATION key frames.

scaleKeyFrames

public java.util.ArrayList<KeyFrameTuple3f> scaleKeyFrames

Temporal key frames for the bone. They are reference extracted from the current animation and they will change every time you play a different animation. They are here to simplify the animation algorithm. These are SCALE key frames.
