Povray extension and force engine and

General Discussion
1

Hi,

I have a couple of questions regarding povray extension and force engine.

The first one is why it does not render force/normal mode vectors? Is there a
quick fix for that?

The second is actually not a question but a remark. It also concerns the force
engine - it seems that the latter displays the normalized vectors and their
length is not affected by the amplitude scaling in the vibrations extension.
Such vectors are often even hard to notice. Molekel for instance allows for
scaling of the vectors.

Cheers, Robert

No, that would be a code bug – I don’t think cylinders or cones are supported by the PovRay export code.

The scaling factor in the vibration window only affects vibrations, not other forces. It’s definitely worth having an option in the force display to scale the vectors.
