= Simple molecular graphics attributes for Feb 2015 Chimera 2

These are graphical molecular attributes that should be part of the C++ molecule classes or their base classes.

== Atom ==
{{{
 none
}}}

== !BaseSphere (base class for Atom) ==
{{{
 drawMode (Sphere, EndCap, Ball)
}}}

== Connectible (base class for !BaseSphere) ==
{{{
 display (true/false)
 color
}}}

== Connection (base class for Bond/!PseudoBond) ==
{{{
 display (true/false)
 radius
 color
 halfbond (color each half of bond to match near atom)
}}}

== Residue ==
{{{
 none
}}}


== Chain ==
{{{
 none
}}}
  
== Molecule ==
{{{
 none
}}}

== Model ==
{{{
 display (true/false)
 color
}}}

== !PseudoBondGroup (global bond settings like Molecule) ==
{{{
 none
}}}

== Notes ==

1. No ribbons.

2. No wire and dot mode.

3. Should color objects be immutable?  Chimera 1 allows redefining a color and having all graphics objects using that color automatically update.  Complex code.

4. How to handle different materials in addition to colors?

5. Keep color hierarchy (model->atom, model->ribbon)?  What about surface colors?
