[worldKit-dev] distorted lines and polygons with <accuplot>

I'm not able to replicate this. Can you provide any more information?

accuplot and lines/polygons are not compatible at the moment.

If you set line thickness to "0" then it won't change while zooming (but it also might be hard to see).

For this to work with non-zero thickness, the lines would need to be redrawn on each zoom. Incidentally,
this would also fix the accuplot compatibility problem.

Agreed, have added a ticket for this. http://worldkit.org/trac/index.fcgi/ticket/116

I have some other emails from you, haven't had a chance to respond til now. Looking now..
