Quads as drawing primitive for surfaces

[Rastar]

I mentioned this before, but think forgot to make an "official" suggestion:

 

I would really love to be able to use quads as a drawing primitive, mainly for using it in tessellation - quads IMHO lead to a more evenly distributed tessellation.

 

So something like

 

Surface:AddQuad(index0..index3)

 

which also implicitly means a

 

glPatchParameteri(GL_PATCH_VERTICES, 4);

 

An unofficial, unsupported, "use at your own risk" version would be suficient for now

[Rastar]

Just as an additional illustration: Using a (mean and inefficient) hack in the control shader, I got quad tessellation. Compare

 

Triangle tessellation

 

to

 

Quad tessellation

 

(both using fractional_odd_spacing). At least for my purposes, I would definitely prefer the more regular structure of the latter.
