[osg-users] osgViewer SCENE_STATS

[Alberto Nortes]

Hello and happy new year to everyone!

I just want to know if it would be possible to retrieve the old 
osgProducer SCENE_STATS in osgViewer. I know  actually we dont have code 
for this functionality, so what would be the first steps (examples, 
guidelines...) to get the same data using osgViewer?

thanks very much, and best wishes!

[osg-users] [RE]Problems when rendering to a FBO texture and using that as a texture.

[Alberto Nortes]

Just to let people know,
I was using Windows x64 with latest Nvidia drivers and I was constantly 
getting this errors and weird behaviour when using FBO´s. Just installed 
Windows x32 and everything is working perfectly...
Thanks for all support.
Regards

[osg-users] Problems when rendering to a FBO texture and using that as a texture.

[Alberto Nortes]

Hi!,

We have migrated all the code to the new osgViewer and everything is working
marvelously, but:
In OSG-2.2, with an Nvidia 7800 GT, I create an FBO to render the scene to a
texture, this works correctly, but later if I want to use that texture as an
input I get the following error:

PixelBufferWin32::wglBindTexImageARB(), failed

This used to work while working with osgProducer, but right now I dont know
what can be wrong. Here is some code:

//Render the current scene to a texture.
camera-setRenderOrder(osg::CameraNode::PRE_RENDER);
camera-setRenderTargetImplementation(osg::CameraNode::FRAME_BUFFER_OBJECT);

camera-attach(osg::CameraNode::COLOR_BUFFER, _texture_fbo);
camera-addChild(*_total_root*);

_root_camera_fbo-addChild(camera);
_root_camera_fbo-addChild(nested_quad_from_camera);
viewer.setSceneData(_root_camera_fbo);

//Then in another part of the code I do:
osg::Texture2D* _imagen_fbo = getTextureFbo();
*_total_root*-addChild(group);
group-getOrCreateStateset()-setTextureAttributeAndModes(0,
_imagen_fbo,osg::StateAttribute::ON); //This last line provokes the warning.


I belive I am doing something really really wrong like accesing the texture
inside the same camera that renders it each frame... Please any comment
would be very helpful.
Thanks!
