It would be useful to be able set separate surface properties
for the interior of opaque closed surfaces that have been made visible
by the clipping planes set in Per-Model-Clipping. These are normally
This could be complicated to implement in a general way.
In my opinion, that's probably not necessary.
The only feature that I really pine for is the ability to make
the interior surface darker/lighter than the exterior surface.
Perhaps a slider could be added to Per-Model-Clipping tool
that allows the user to make the backface polygons darker or
lighter than the regular polygons. (Perhaps the default
should be about 25% darker. That would look pretty and I
hope it would be easy to add.)
Another feature that would be useful is the ability to make the
closed surfaces look solid so that when you cut into them, instead
of seeing the interior, a polygon face is added to close the surface
and make it look like a solid object. (For example, lighter-colored
surfaces in the cartoon:
I realize these features should be low on the priority list.
Maybee a quicky feature to implement when you get board working
on the slow, difficult, useful stuff.
