If you just did this
Transform3D rotate = new Transform3D();
rotate.rotY(Math.toRadians(90));
rotate.rotX(Math.toRadians(90));
only the rotation about x would take affect. This is because when you use these
rotate commands, it clobbers everything else in the matrix.
as in the javadoc for these methods
public void rotX(double angle)
Sets the value of this transform to a counter clockwise rotation about the x
axis. All of the
non-rotational components are set as if this were an identity matrix.
so, to do the double rotation, you could do this
Transform3D rotateY = new Transform3D();
Transform3D final_rotate = new Transform3D();
rotateY.rotY(Math.toRadians(90));
final_rotate.rotX(Math.toRadians(90));
final_rotate.mul(rotateY);
this will give you the double rotation.
