Hey, Hmm ... do you actually perform the update/call/draw inside the handler or request a paint event and then perform the draw there? I ask because I don't really use the OnPaint handler for much, other than to create a wxPaintDC.
I also had to make some updates due to osgGA changing and perhaps I've created some strange timing issue with the rendering ... -----Original Message----- From: [EMAIL PROTECTED] on behalf of J.P. Delport Sent: Fri 8/18/2006 8:13 PM To: osg users Subject: Re: [osg-users] Producer and Win32 Hi, I'm using wxGLCanvas with SceneView and also rendering (update, cull, draw) in onIdle. On Linux nothing broke with OSG 1.1.1 (had to make some osgGA changes). On Windows I am however still using some OSG CVS version post 1.0, so I'm not sure about the behaviour of the latest version. I have SetCurrent only inside onPaint. cheers jp Gian Lorenzetto wrote: > Yeah, I call it before initialising the scene graph and before rendering. > There seems to be a valid graphics context as geometry (including textures) > drawn in immediate mode work fine. > > I've also moved to using the OnIdle handler to generate calls to the render > method, but don't think that would be interfering ... > > Are you using OSG with wxGLCanvas currently?
