[Gate-users] sine movement

[Marc Chamberland]

Hi again, Regina!

I had a quick look at the source code for the sine motion in Gate and I think it would be easy to make it a sine to the fourth power.

Look at the file GateOscTranslationMove.cc which you will find under [your Gate installation folder]/source/geometry/src/

On line 53 of that file, you see the following:

m_currentTranslation =  m_amplitude * sin ( 2. * M_PI * m_frequency * aTime + m_phase);


I think you could simply change it to the following:

m_currentTranslation =  m_amplitude * pow( sin ( 2. * M_PI * m_frequency * aTime + m_phase), 4);


After you make the change, you will need to save the file, then re-compile Gate.

I hope this helps!

Marc
