Hello,
I have read that a good way to antialias lines in openGl is to use a texture map of an antialiased circle and map the coordinates of a rectangular set of vertices to it, like this:
However, I’ve also read about adding a layer of polygons around the outside of a rectangle, with the outer vertex alpha equal to 0. That is what I do now, and it looks fine.
But I am wondering if the other way is faster, maybe? Which technique is better?
Thanks
Bob
