示例1: rotateUpTo

import com.jme3.math.Quaternion; //導入方法依賴的package包/類
/**
 * <code>rotateUpTo</code> is a utility function that alters the
 * local rotation to point the Y axis in the direction given by newUp.
 *
 * @param newUp
 *            the up vector to use - assumed to be a unit vector.
 */
public void rotateUpTo(Vector3f newUp) {
    TempVars vars = TempVars.get();

    Vector3f compVecA = vars.vect1;
    Quaternion q = vars.quat1;

    // First figure out the current up vector.
    Vector3f upY = compVecA.set(Vector3f.UNIT_Y);
    Quaternion rot = localTransform.getRotation();
    rot.multLocal(upY);

    // get angle between vectors
    float angle = upY.angleBetween(newUp);

    // figure out rotation axis by taking cross product
    Vector3f rotAxis = upY.crossLocal(newUp).normalizeLocal();

    // Build a rotation quat and apply current local rotation.
    q.fromAngleNormalAxis(angle, rotAxis);
    q.mult(rot, rot);
