Yes it is. It is just made for you automatically. FBO renders to a
texture and the image is read from this texture when you attach it to
the camera.
I suggest attaching a texture (to the same buf
Hi Cedric,
I found on https://github.com/cedricpinson/osgexport/pull/4
a new commit.
Is the animation included now and working ?

Change my question. I followed the osgvolume example. I made a bit different
to use setImage function.
osg::ref_ptr tile = new
osgVolume::VolumeTile;
osgVolume->addChild(tile.get());
osg::ref_ptr osgImage = new osg::Image;
osg::
Hi Clement,
I really don't know what is going on at your end, what you are
expecting, what you've coded, there is no way I can provide any
answers.

Hi, J.P.
the camera isn't rendering to a texture. In my programme, camera is set
to be prerender, render target is FRAME_BUFFER_OBJECT, I attach the
camera to an image, in order to get the bufferdata via image. the image
data type is allocated as GL_FLOAT.
Related setup details are listed
HI Robert,
I replaced the program from coin to osg and I don't know why osg display
the image from the same volume data is different from coin. I think the
problem is on texture format since I changed to use different parameter of
texture format such as GL_RGBA, GL_RGB16F_ARB, GL_RGBA8.
Hi Clement,
I can't work out specifically what you are expecting to happen. What
coin does is something I have no experience with so can't comment on
how you might try to obtain a similar image.

Hello Sebastian,
You are right. I have other errors in the shader when such warnings
happened. After I correct them, it works normal!
Thank you very much for the explanation!
