VertexSwap?

[Sylvain]

Is there any VertexSwap command under Gl which provides the possibility to make the strips turn at 90°?? I mean that any polygon strip will not be forced to use the last two points to create the next triangle!! http://www.opengl.org/discussion_boards/ubb/smile.gif)
Thus A,B,C sequence corresponding to the previous triangle, any new D point should add
a new triangle set as B,C,D so what? now with
vertexSwap it should become A,C,D..
Any reference? thanks! http://www.opengl.org/discussion_boards/ubb/smile.gif

nope, there isn't. i've read a paper about mesh triangulation where they make a point of stating that opengl cannot do this (unlike iris gl that can). The simple soln (well, _THE_ solution) is to dupe your vertices.
