What to expect from Meshes in OpenGL 2 ES?

  i'm not impatient, just upping this post. so if you can tell if eventually meshes will be antialiased, that would be a useful info.

  Now I can add getVertex, getIndex, getColor and getTextureCoordinate. Do you need any other get* function?
  
  Before supporting antialiasing, it's possible to provide a Lua plugin for http://www.angusj.com/delphi/clipper.php and a triangulator. So that after constructing your arbitrary polygon, you can offset it 1 pixel with clipper library and draw an opaque to transparent border to get antialiasing effect. We can make a plan with @ar2rsawseen to provide this plugin soon. What do you think?

  @atilim, good to have you back, actually for a future project for some 2d shadows i was considering exactly the same clipper library to do some polygon operations, i emailed the guy about a lua version, he said there is no such thing. so if you could make a plugin for it, that would be awesome not just for antialiasing.
  
  about antialiasing directly, should i understand your comment in the way that it may not be initially available with opengl 2 but later it is possible that you add this feature?
  
  for my use (animated drawing app) actually i just use quadrangles and i need them to be antialiased on two opposide sides (these are segments of the stroke), and i use the same technique you propose, just that even no polygon operations are needed, the simple extending of the quadrangle can be done with a few math related lines of code.
  
  so in a nutshell:
  -clipping lua plugin would be great.
  -get functions will be great.
  -mesh antialias at some point would be good too.
  
  thanks

  Exactly.
  
  Then we'll implement clipping lua plugin. And I've already added get* function.

  I suggest add some native base shape apis, for example circle, arc, polygon, line with smooth endpoints and corners.
