[osg-users] different materials for a geometry and highlight

[Gianni Ambrosio]

Hi Sebastian,
in attachment you can find a movie of what I implemented with primitive sets. That's exactly what I need.
The "road" is initially gray. Then the user choose a color (pushing in my example 1,2,3 or 4 key) and picking the road surface triangles are coloured with the current color.

Since you said what I implemented with primitive sets is not the right way to do, then I'm trying to change my mind using the approach you suggested (i.e. textures) to reach exactly the same behaviour. In this case I could use a "monochromatic" image (to mimic the behaviour of my example) or a nice texture loaded from file. A nice texture anyway is not a must.

In attachment you can find also the example code I run to record the movie.

Hope this helps,
Gianni
