The goal is having an OpenGL binding in Lisp, which doesn't require
people to think about C-ish things like having to pass pointers to
arrays
in order to get the current color.
The guys at pyopengl did a mirror of OpenGL. I don't know what
should you do in lisp-gl, but for my graphical library I decided to
diverge from the SDL lib.
We don't really diverge and try to keep the mapping between the C
and Lisp names obvious. The macro in question is pure sugar and
doesn't have a C equivalent.
(defun draw-foo ()
(gl:with-primitives :quads
(gl:color 1 0 0)
(gl:vertex -1 -1 )
...
(gl:vertex 1 1)))
instead of
(defun draw-foo ()
(gl:begin :quads)
(gl:color 1 0 0)
(gl:vertex -1 -1)
...
(gl:vertex 1 1)
(gl:end))
