Some one told here for Opengl, I never used it before. Can it be used for GUI Components. What Files are distributed along with it.
And any startup examples.
I've never used openGL either, but a search reveals
http://wiki.freepascal.org/OpenGL as one source of information.
As for examples: In Lazarus, choose
Tools -
Example Projects. Then type opengl into the filter box. There are four opengl example projects that ship with Lazarus.
As I say, I've never used OpenGL either, so I'm not certain that the info I've given is the best starting place. Good luck :-)
