ArrayElements emulation wrapper

Could this be done?

As in a wrapper for vertex arrays? Sure, Quake 3 has a simple enough one. The only real difficulty is when you get glDrawElements (GL_TRIANGLES, ... being used to concatenate multiple polygons (which is what most modern titles do) as you would end up with (numverts - 2) * 3 verts per polygon; if you're vertex-bound (which you're probably not) that would make things significantly worse. (Q3A does runtime strip finding in that case, which seems a mite hairy to me, although it obviously worked well enough back then.)

I don't see why you'd want to though as vertex arrays are standard since OpenGL 1.1 and will always work faster than immediate mode.

Some MiniGLs don't.....

Should be only the original Voodoo 1 (and the mini GLs from 97 onwards should support them as Q2 used vertex arrays). Seems a lot of work for hardware that nobody really has any more.

SGL MiniGL 1.0.x.x do not support it, and Rendition VeriteGL doesn't support it I think either


I did attempt to make one, but unfortunately all I ran into is opengl cheats like wallhacks/depthhacks which are irrelevant to my quest.
