Printing w/tubes

[Jarvist Moore Frost]

I believe that Aven only uses the openGL canvas for drawing. I'm not sure
therefore if there is a way to increase the resolution to print quality.
Certainly with other display software in the biosciences, because its going
back and forward to the graphics card is tied by the maximum size of the
window, and higher resolution outputs are usually achieved by a dedicated
software renderer, Ray Trace or otherwise.

You may be interested in some work outputting the .3d file to a format
suitable for loading by Pymol, which has a nice built in ray tracer for
doing arbitrary resolution renders (with high quality anti aliasing, etc).
Currently the passage tube data is not used, my method synthesised an
effective tube diameter from the shot length, but the data manipulation
steps are a bit of a hack and Unix only.
Thomas Holder improved on this by writing a plugin for pymol that directly
loaded the .3d file (I think he posted his code here a while ago), but
again, currently I believe it throws away the passage tube data, but it
should be extendible to make some use of this information.
