[Gate-users] Multiple rotations

[Fares Alhassen]

Dear all,

Does anyone know how to perform multiple rotations on shapes? For example,
if I want to rotate a geometry by 47 degrees about the x-axis and 27 degrees
about the z-axis, how would I go about doing that?

If I write

/gate/volume_name/placement/setRotationAxis 1 0 0
/gate/volume_name/placement/setRotationAngle 47 deg
/gate/volume_name/placement/setRotationAxis 0 0 1
/gate/volume_name/placement/setRotationAngle 27 deg
  
GATE will simply use the last specified rotation axis and angle. Is there a
way I can specify a rotation matrix for my volume?

Sincerely,
Fares
