FrustumGeometry Orientation

hi @omar and all
I am trying to create a Frustum Geometry using heading, pitch, and roll, but the Frustum Geometry’s orientation doesn’t seem right. It is different from the orientation.

If anyone can help me solve this problem, I would be very grateful.

Thank you

i have the same problem, i need to get the camera position and rotation, save and use this coordinates after to bring back to position, but each time the position is ok, but rotation no
