Hi,

I am trying to rotate a object3d, and neither using rotationX/Y nor
pitch/yaw gives me the result that I expect.

The issue seems that these functions will rotate the object's own
coordinate system.

For example, when I rotate the obj around the y-axis (a horizontal
rotation), then I want to rotate the object around the x-axis. At this
point, from my point of view, the x-axis become the z-axis and the
rotation looks to me like it is rotating around the z-axis.

Are there functions that allow me to rotate object, but using the
whole model's coordinate system? Since these rotation actions are
initiated by user (me), it only makes sense if it rotates according to
the global coordinate system.

thx.
Ronald
