Hi Yvonne, it works so far. Now I have just one more thing, a warning: WARNING: FBO render post OpenGL Error: stack overflow! or WARNING: FBO render post OpenGL Error: stack underflow! What does it mean? Is it an OpenSG or OpenGL warning? regards, Oliver Oliver Kutter schrieb:
Hi Yvonne, Yvonne Jung schrieb:Really? What happens if the texture changes to another texture with the same size?Hi Oliver, this only has to be done if the image size changes.I have different viewports with different textures. But I'll have to use the "double buffer" concept, because I'm using the output of an fbo as input for the next step, and then change the textures, so that the next step is the input for the step after the next step.If you have many textures with different sizes in which you want to render, it is better to assign each of them a different FBOViewport.BTW, perhaps you also want to try a more current daily build, because there have been some fixes since 1.8.I'll try...Bye Yvonneregards OliverAm Fr, 9.05.2008, 18:52, schrieb Oliver Kutter:Hi Yvonne, thanks, that's it. But now it is very very slow. Can't I just call the dirty function once or is there another way to do whatever this function does? regards, Oliver Yvonne Jung schrieb:Hi Oliver, you also need to set the dirty flag. Bye, YvonneHi, 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 ------------------------------------------------------------------------ ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
