But again this is somewhat moot regarding Croquet: it's written against an ancient version of OpenGL (I believe 1.6 + extensions that get it *roughly* to 2.0 feature-wise) which most desktop drivers are still backwards compatible with. So you can just use the calls already there. You'd really only need to worry about regenerating the API if you wanted to update Croquet to take advantage of the latest OpenGL/features and/or run it under OpenGL ES. This would not be a trivial task since you'd probably have to rewrite, or at least significantly restructure, most of Croquet to make it work.<br></div></div></div><br><div class="x_1217646067gmail_quote"><div class="x_1217646067gmail_attr" dir="ltr">On Wed, Mar 11, 2020 at 5:58 PM gettimothy via Squeak-dev <<a target="_blank" href="mailto:squeak-dev@lists.squeakfoundation.org">squeak-dev@lists.squeakfoundation.org</a>> wrote:<br></div><div><br></div></div></div><blockquote style="margin: 0.0px 0.0px 0.0px 0.8ex;border-left: 1.0px solid rgb(204,204,204);padding-left: 1.0ex;" class="x_1217646067gmail_quote"><u></u><div><div style="font-family: Verdana, Arial, Helvetica, sans-serif;font-size: 10.0pt;"><div>btw, the glMatrixMode:mode method tells us that it was automatically generated.<br></div><div><br></div><div>by what?
