Hi,
I'm trying to make efficient fluid simulation with osg
I've just found this page :
http://www.mail-archive.com//msg05568.html
It look pretty great as my 1 camera per slice code is very CPU time consuming.
I develop a geometry shader that change gl_layer value per primitive.
It work so i change my texture my texture attachement to camera's FBO as follow:
Code:
for(int i=0;i<_depth;i++){
//one cam per slice
_cameras[i]->attach( osg::Camera::COLOR_BUFFER,tex,0,i,false);
}
to
for(int i=0;i<1;i++){
//one overalll camera
_cameras[0]->attach(
osg::Camera::COLOR_BUFFER,tex,0,osg::Camera::FACE_CONTROLLED_BY_GEOMETRY_SHADER);
}
But this change make a crash:
Code:
RenderStage::runCameraSetUp(), FBO setup failed, FBO status= 0x8da8
Any idea?
Thank you!
Cheers,
Julien[/code]
