FYI it was quite trivial and is commited in r1744.

Ok, thanks for information. It is interesting, and I will try to find out
how it was made.

Actually, what is the difference between  Blueprints and Bugs?
Blueprints are proposals? So, maybe it is a blueprint?

Re: [Yade-dev] Facet Highlight

2009-08-26 Thread Václav Šmilauer 
ok, I get your point. That is caused by the way openGL rendering code is
written; somehow boxes have glossy surface and facets don't. I am in no
way familiar with opengl, it is mostly code Olivier has written in the
prehistoric (= pre-python) period. If you know something about opengl,
go for it, if you don't or don't have time, you can file bug about that.

Once I was trying to make specular light used, but then I gave up. The
chameleon highlight is made by changing periodically the ambient light,
the color of bodies doesn't have to be changed that way.

There is no special box highlight... The only highlight it the
"chameleon" one, the rest is picking brighter color for that body in
question.

Is it difficult to make "normal" highlight (like BOXes do), and "chameleon"
make like an option?

What files should I inspect for that?

Eh, you are passing highlight to utils.facet... that is something
different from what I said. I added that parameter in r1939 though so it
works now as you expect.

The trick is that the **kw params are passed to
Body::physicalParameters, whereas highlight is property of
Body::geometricalModel, therefor has to be passed separately.

Anyways, I would like to remove the obnoxious difference of
GeometricalModel and InteractingGeometry at some point... But that would
need larger discussion.

> Is it possible to highlight facets like boxes do?

Yes, but the facet must not be drawn as wire. If #3 is facet, do
something like this:

bs=O.bodies[3].shape
shape['wire']=False
shape['highlight']=True

(translated straightforwardly to c++)

Note that if you define onBodySelected function in python, it is called
as callback when you select a body with shift+right mouse button:
scripts/simple-scene.py shows that. In that functions, you can do other
things; I used it to dump all interaction properties of that body to the
console etc, for debugging.
