示例1: drag
//Mouse drag, calculate rotation
public void drag(Point NewPt, Quat4f NewRot)
{
//Map the point to the sphere
this.mapToSphere(NewPt, EnVec);
//Return the quaternion equivalent to the rotation
if (NewRot != null)
{
Vector3f Perp = new Vector3f();
//Compute the vector perpendicular to the begin and end vectors
Vector3f.cross(Perp, StVec, EnVec);
//Compute the length of the perpendicular vector
if (Perp.length() > Epsilon) //if its non-zero
{
//We're ok, so return the perpendicular vector as the transform after all
NewRot.x = Perp.x;
NewRot.y = Perp.y;
NewRot.z = Perp.z;
//In the quaternion values, w is cosine (theta / 2), where theta is rotation angle
NewRot.w = Vector3f.dot(StVec, EnVec);
}
else //if its zero
{
//The begin and end vectors coincide, so return an identity transform
NewRot.x = NewRot.y = NewRot.z = NewRot.w = 0.0f;
}
}
