[Gate-users] Use of setRotationAxis and setRotationAngle

[Christian Wietholt]

Dear GATE users, 

I am trying to use GATE to simulated data of a SPECT
system with a misaligned detector. I would like to be
able to rotate the detector around its three axes at 
different angles with the commands: 

setRotationAxis
setRotationAngle

Using the following sequence:

/gate/crystal/placement/setRotationAxis 1 0 0
/gate/crystal/placement/setRotationAngle 3 deg
/gate/crystal/placement/setRotationAxis 0 1 0
/gate/crystal/placement/setRotationAngle 2.5 deg
/gate/crystal/placement/setRotationAxis 0 0 1
/gate/crystal/placement/setRotationAngle 5.3 deg

only the last rotation is considered and the previous
rotations are ignored.

If I uses something like this:

/gate/crystal/placement/setRotationAxis 1 1 1
/gate/crystal/placement/setRotationAngle 5.3 deg

I can rotate around all three axes, but only by 
"5.3" degrees for each angle, not at different angles.
What would be the sequence to rotate for example:

x = 3.0 deg
y = 2.5 deg
z = 5.3 deg

Unfortunately, I am unable to figure it out from the 
users manual and was unable to find anything in the 
GATE User Talk archives. 

Thank you for your suggestions. 

Christian
