Hello<br> I've made a patch that creates GEMglvertex3f dynamicaly, it's attached,<br> and needs a little fix I didn't have time to do (it's about attributing default coordinates).<br> Do you think it's a good idea? Anyone did this before?<br> In other words, am I loosing my time with making these kinds of abstractions?<br> <br> Patco.<br><br><b><i>Alexandre Quessy <listes@sourcelibre.com></i></b> a écrit :<blockquote class="replbq" style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;"> Hi, <br><br>A good idea would be to make a library of Gem abstractions using openGL functions, dynamic objects creation and the [repeat] and [any] objects.<br><br>Then, we could use lists of 3D vectors, do arithmetics on them, and render it at the end of the chain. <br><br>Such a library could be named extensions/dyngems. Any people in the room wants to work on this ?<br><br><br>-- <br>Alexandre Quessy<br><a
