Examples of com.ardor3d.math.Matrix3.lookAt()

com.ardor3d.math.Matrix3.lookAt()
Modifies this matrix to equal the rotation required to point the z-axis at 'direction' and the y-axis to 'up'. @param direction where to 'look' at @param up a vector indicating the local up direction. @return this matrix for chaining

        SkeletalDebugger.bone.setWorldTranslation(stPnt.add(endPnt, store).divideLocal(2.0));
        Vector3.releaseTempInstance(store);


        // Orient bone to point along axis formed by start and end points.
        final Matrix3 orient = Matrix3.fetchTempInstance();
        orient.lookAt(endPnt.subtractLocal(stPnt).normalizeLocal(), Vector3.UNIT_Y);
        final Quaternion q = new Quaternion().fromRotationMatrix(orient);
        q.normalizeLocal();
        SkeletalDebugger.bone.setWorldRotation(q);


        // Offset with skin transform
