Dear All,
I recently saw Volume Rendering in the Getting Avo2 to release email and
wanted to start some discussion. I recently exposed the Gaussian Cube file
type to render MOs (pull request was submitted, including an example to
avogadrodata) and I had some ideas for improvements:
1) Is there a good place to submit improvements (not issues), and possibly
rank the importance of such an improvement? I would like to help with
important issues instead of just issues I am particularly interested in.
In the issue tracker, but tag them as enhancements. Bugs should be
tagged as bugs.
2) Instead of Set background color in View tab, it might be better to
have a Color Preferences where one could set many different colors
(including opacity etc).
Sounds reasonable.
3) Alignment tool, click two atoms, align to some axis (for exporting images
mainly)
I had been meaning to port this from Avogadro 1 - it is a simple tool
I wrote for similar purposes (including QM with electric fields).
4) I have suggested this to Marcus previously, but exporting graphics in
vector formats for publications. The PNG images generated currently are
lackluster. I dug into this a little, but I lack experience with Qt and the
concepts were a bit over my head at the moment (working on that!).
Vector graphics is tougher, I would like to finish off some of my work
on bringing back POV-Ray/ray tracing export. For a scene of any
complexity even when you export the vector it can often be too much
for the rendering engine in Adobe Reader for example. After having
done this in Avogadro, and seen results from VTK I would say you are
best off rasterizing the 3D and exporting text, lines, etc.
We are pretty focused on getting some essentials finished up, as per
Geoff's post, but if you have time and want to develop some of these
features I would be interested in what you come up with.
Best,
Marcus
