Hello every one,
i want to render to fboviewport then captures the rendered image to a file i
refered to
http://www.mail-archive.com/[email protected]/msg08740.html
but i still have problems
ImagePtr fbotexi = Image::create();
beginEditCP(fbotexi);
fbotexi->setPixelFormat(Image::OSG_RGBA_PF);
fbotexi->setWidth(w);
fbotexi->setHeight(h);
fbotexi->setDimension(2);
endEditCP(fbotexi);
TextureChunkPtr fbotex = TextureChunk::create();
beginEditCP(fbotex);
fbotex->setMinFilter(GL_LINEAR);
fbotex->setMagFilter(GL_LINEAR);
fbotex->setTarget(GL_TEXTURE_2D);
fbotex->setInternalFormat(GL_RGBA8);
fbotex->setImage(fbotexi);
endEditCP(fbotex);
beginEditCP(m_fbovp);
m_fbovp->setSize(0, 0, w-1, h - 1);
m_fbovp->setStorageWidth(w);
m_fbovp->setStorageHeight(h);
m_fbovp->setParent(m_window);
m_fbovp->setCamera(m_orthocam);
m_fbovp->getTextures().push_back(fbotex);
m_fbovp->setRoot(rootNode());
m_fbovp->setBackground(SolidBackground::create());
m_fbovp->setReadBuffer(true);
m_fbovp->setDirty(true);
endEditCP(m_fbovp);
SolidBackgroundPtr sbg =
SolidBackgroundPtr::dcast(m_fbovp->getBackground());
beginEditCP(sbg);
sbg->setAlpha(0);
sbg->setColor(Color3f((float)100/255,(float)100/255,(float)100/255));
endEditCP(sbg);
m_fbovp->render((RenderAction*)m_mgr->getAction());
fbotexi->write("D:\\snake\\getafreelancer\\Render Image Of 3D Using
OpenSG\\898121_3ds\\archr01_render02.png"); // the dll crashes here it creates
the file with no real content
Thanks for advance,
Abdalla
