Re: [Goptical] Line along optical axis

[Richard Graham]

Hi Alexandre,

While it would probably be a good idea to add the ability to
disable/customise the optical axis line, my main issue is that it is
being drawn incorrectly in the first place.

It seems that the bounding box for lenses with a custom (rotational)
curve are calculated incorrectly in the z direction. For example in my
case the z limits for the bounding box for the left lens come out as
-236.365 and 39.919 but I think they should be 6.35 and 39.919+6.35
respectively.

Looking at the code it seems like this must arise when the bounding box
coordinates are transformed but I loose track of it then.

Any ideas?

Regards,
