Hello Stéphane,
I do remember your comment on the subject here…
I am sorry but adding opacity in the general Scilab graphic model is a HUGE work beause it would necessitate to revamp the whole renderer module and it cannot be something else than a long term milestone. However, if you can afford to hire a Java/C++/OpenGL specialist we would be glad to help him to dive into Scilab project!
So, although it will most likely exceed my programming skills … out of interest I’d like to have a look.
Just: Can you give a hint where to look?
