Hi all, I'm newbie about OpenGL, and I try to find out a tutorial openGL about paint. I think it is easy for newbie as me to learning simple things about OpenGL 2D,

 

So, anyone know tutorial paint or source code paint by OpenGL?

What exactly do you mean by "paint"? Paint is sometimes used in 2D graphics for the color and pattern used for filling the areas, i.e. in so-called vector graphics. Or do you even mean the simulation of pens or brushes and gouache or oil color and such things? Could you clarify please ...

 

In short: Tutorials for the above are … not existent (to my knowledge). I know of some sites and blogs that has a few articles / posts about vector graphics utilizing OpenGL, and I know of some academic papers about stroke and brush rendering utilizing OpenGL. If it is of interest, I can post them.

 

However, OpenGL is made for 3D, and that has an impact on how simple 2D in general: It is more difficult. Rendering vector graphics become somewhat even more difficult when line endings, line miter, anti-aliasing and such comes into play. And the simulation of "real" painting is so difficult that it is IMHO absolutely not a beginners playground.
