Hi Daniel,<br>
<br>
Looking at the code I think it would not be too hard to thicken
the green selection outline. We can test the appearance with a one
line modification of the C++ code. I've added this to the feature
request list.<br>
<br>

<br>
The fact that selected objects don't show a green outline when they
are under a transparent surface is bug 7777 reported over a year
ago.<br>
<br>
<a class="moz-txt-link-freetext" href="http://plato.cgl.ucsf.edu/trac/chimera/ticket/7777">http://plato.cgl.ucsf.edu/trac/chimera/ticket/7777</a><br>
<br>
The technical problem is that the depth buffer is being written when
drawing transparent surfaces. This is needed for one-layer
transparent surfaces (the default for molecular surfaces) but is not
required for multi-layer transparent surfaces (the default a few
years ago). Even for multi-layer transparent surfaces it is
desirable to write the depth buffer when multiple transparent models
are used to minimize incorrect transparent object rendering (depth
order wrong).<br>
<br>
Here's one idea for a solution. Green selection outlines could be
shown even for objects hidden behind opaque surfaces and models. It
would be like x-ray vision. I think this may be nice because when
selected items are not seen because they are covered it is hard to
know what is selected. But it may be confusing to see these x-ray
silhouettes -- would have to try to know. I think it is easy to
try.<br>

type="cite">Hi everyone,<br>
Two requests that would help with interactive demonstrations to
large audiences:<br>
In preferences/background, the selection mode can be "fill" or
"outline". Is it possible to add a line-width option for outline?
I want to increase the thickness of a selection outline to make it
easier for my students to see when I'm projecting an image, but I
don't want to use the fill option and lose residue color
information.<br>
<br>
I suspect that's an easy fix, but this one might be more
difficult:<br>
Transparent surfaces are very informative when combined with
underlying ribbons or stick representations of atoms. But if a
residue is visible beneath a transparent surface, selecting it
(via the command line) does not show the selection outline. Is it
possible to make that work? <br>
Thanks,<br>
