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 href="http://alexandre.quessy.net">http://alexandre.quessy.net</a>
