Any ideas on where > I should look for the problem? Anyone manage to use clutter-md2 in > 1.0? I've just pushed some patches to the git repo¹ to get it working with Clutter 1.0. If you could check whether this fixes it for you that'd be great. The project still could do with a lot more work to update it properly however. It's still using raw GL calls to render and this could be avoided now that Cogl has the CoglVertexBuffer API. The rendering is currently quite inefficient because the vertices are uploaded to GL at every render and it uses multiple draw calls. It also defines a ClutterBehaviourMD2 class which would not be neccessary if the properties on ClutterMD2 were changed so that you could use the clutter_actor_animate API. You may be interested in a similar project² I started to load PLY files instead of MD2. If your models are coming from Blender and you aren't using the animation features of MD2 you may have better luck using that library instead. It uses VBOs without any raw GL so it should be more robust and also render faster. It is also somewhat more flexible because it can render with any Cogl material rather than a fixed list of skins. There was some discussion about this on the mailing list³. I'd be very interested to know what your project is if you are able to say :) Hope that helps. - Neil ¹ git clone git://github.com/bpeel/clutter-md2.git ² http://bugzilla.openedhand.com/show_bug.cgi?id=1983 ³ http://lists.o-hand.com/clutter/3582.html -- To unsubscribe send a mail to [email protected]
