Hi,
I was not working for a very long time with OpenSG. At that time I used
OpenSG 1.6 with an alpha Version of Yvonne Jung's FBOViewport class.
Now I was trying to get it running again with the Windows Install
Version 1.8. As information, I'm doing some general purpose computation
with the fbo class.
It's nearly working, but when I'm rendering to texture and I'm changing
the size of the texture, e.g. 256x256 to 128x128, I'm getting this warnings:
WARNING: FBO render post OpenGL Error: (null)!
WARNING: 8cd9: framebuffer FRAMEBUFFER_DIMENSIONS
and I think, this leads to the fact, that my programm is not working
correctly.
This is my code how I'm changing the size of the texture and the fbo
storage. The code was working the the old 1.6 and alpha fbo class version.
beginEditCP (fboViewport, FBOViewport::StorageWidthFieldMask |
FBOViewport::StorageHeightFieldMask);
fboViewport->setSize(0, 0, width-1, width-1);
fboViewport->setStorageWidth(width);
fboViewport->setStorageHeight(height);
endEditCP (fboViewport, FBOViewport::StorageWidthFieldMask |
FBOViewport::StorageHeightFieldMask);
beginEditCP(fboImage);
fboImage->set(Image::OSG_RGBA_PF, width, height, 1, 1, 1, 0, NULL,
Image::OSG_FLOAT32_IMAGEDATA);
endEditCP(fboImage);
Anyone ideas?
regards,
Oliver
