Hi,
I'm looking at a good approach to draw antialiased lines. It seems like the best approach is to use a circle texture, and tessellate the lines. This is described nicely here: http://iphone-3d-programming.labs.oreilly.com/ch06.html#AaLinesWithTextures

Is there any way to easily achieve this in cocos2d? I don't want to reinvent the wheel if possible, so I'm asking first, after having search the forums, and the documentation without much success.

Thank you

I haven't seen anyone post about this before, so I would encourage you to take the oreilly example and port it to cocos2d (and post it back here for everyone to use).

There is also an example of the same technique in the PowerVR SDK for iPhone, which you may find as a good resource as well: http://www.imgtec.net/powervr/insider/sdk/KhronosOpenGLES1xMBX.asp

Thank you. I'll try to give it a shot, but I need to understand some OpenGL concepts before I do.

@CJ: I can't find the example you mention. Can you be more specific?
Thank you

Update: Never mind, found it.
