Re: [osg-users] Maximum database size without paging

Hi Kiff, There is a good chance that if you model is too big to fit in memory then you are going to have problems. The best you can do is compress your textures, and possible swtich off display lists. To compress textures try: osgconv --compressed-dxt1 mymodel.flt mymodel.ive As for

[osg-users] Suggestion for osg::Depth in RTT setups

All, We are using osgViewer::CompositeViewer. We have cases in which we switch certain things to become transparent during runtime, depending on user input and the view being drawn. In order for those things to contain other transparent elements (particles) we must disable writing to the depth

Re: [osg-users] Suggestion for osg::Depth in RTT setups

Hi John, My guess is that the type of viewer will be irrelevant, i.e. the problem will still occur on osgViewer::Viewer, or even a SceneView based viewer, my guess is that there is an issue with management of osg::State when moving between the cameras. I don't know of any existing problem in

[osg-users] Question about osg::Fog and RTT setups

All, Why is it that osg::Fog, and maybe glFog(), work as expected in RTT setups if FRAME_BUFFER_OBJECT is chosen as the RenderTargetImplementation on your Camera, but if PIXEL_BUFFER/_RTT are chosen, you must re-load the scene? I think that people are under the impression that when GLSL shaders

Hi John, If you are using GLSL then osg::Fog/glFog will only provide the inbult fog uniform values will be available to the shader, but no fog will be applied unless you do something with them nothing will happen. If Fog is being applied when you are expect to that a subgraph is using GLSL then

I must admit, due to both my own and others struggles getting DLLs properly locationed, I've been very tempted to build as many 3rdParty libs as possible in only static configuration. That minimizes the runtime dependency chain, so we'd only have to deal with OSG finding its own DLLs. I dont

Re: [osg-users] Render to 3D texture setup.

Hi, Robert. I'm the user. It's very easy to render to 3D texture. By reading NVIDIA SDK 10, we should know each render pass render a scene to a slice. So, we can do this in OSG by setting numbers of camera. OSG camera code has a function: camera-attach(Camera::COLOR_BUFFER, txt3D.get(), 0, z,
