Re: [osg-users] Problem with corrupted textures when sharing instances of models loaded from IVE format.

Hi Jp, Thanks for this info. I wrote a node visitor to change the texture setting after load by calling texture-setUnRefImageDataAfterApply(false); and that does indeed seem to fix the problem, so I'm pleased others have come up with the same fix. Though I'm now wondering if I still need to

Re: [osg-users] Problem with corrupted textures when sharing instances of models loaded from IVE format.

Hi Robert, To answer your question about how I manage the graphics contexts. I just create a new one for the window handle provided by each instance of my browser plugin e.g Code: traits-inheritedWindowData = new WindowData(hWnd); gc = osg::GraphicsContext::createGraphicsContext(traits);

Hi Joel, This is perfectly normal, it's just a global object initialising of your wrapped class associated with the REGISTER_OBJECT_WRAPPER. It'll get cleaned up automatically on exit. Robert. On 14 January 2012 02:57, Joel Graff pair_o_gra...@comcast.net wrote: Hello, I recently noticed

[osg-users] Help:Is there a way for a single fragment to know its index during per-fragment operation?

Hello, In fragment shader, I would like to chage the fragment colour according to the fragment's index. Here index means integer number pair(x,y), where 0xxRes, 0yyRes, provided that viewPort has xRes * yRes pixels. Is there a way to achieve that? Thank you in advance! Shuiying

Re: [osg-users] Problem with manipulating the projection matrix

Hi Shayne, this sounds like a possible solution. I'll try it out and let you know if it is working. Thank you! Cheers, Sven -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=44834#44834 ___ osg-users

Re: [osg-users] Help:Is there a way for a single fragment to know its index during per-fragment operation?

Hi Shuiying, The fragments coordinates(or index as you call it) can be accessed via gl_FragCoord. This will give unnormalized device coordinates (i.e. [0,xRes] [0,yRes]) which are also called window relative coordinates If you pass your screen resolution as uniform vec2 you can normalize them

[osg-users] Frame syncing over multiple contexts

Hi, I am trying to figure out how to keep multiple graphics contexts in frame sync. My operating system is Windows XP SP3. My graphics is NVidia Quadro NVS 290 with the latest driver 276.42. I'm using OpenSceneGraph 3.0.1 compiled with Visual C++ 2005 for win32. I have vsync on in the driver

Re: [osg-users] Very odd behavior starting OSG app

Robert, Thanks for the quick reply. After a little additional testing (knowing what you've told me), I'm starting to suspect I've got bigger problems than I thought. Am I right in assuming that serialization for user classes doesn't support multiple inheritance? The situation is thus: I
