Re: [osg-users] [osgPPU] How to use osgPPU in an environment withz several slave cameras?

Hi Daniel, the text HUD shows up correctly. Only the wallpaper is missing. I create it by a separate camera in PRE-RENDERmode. Here ist the code snippplet: === /** This method creates a HUD-Window for a wallpaper */ void Cl_3Dview_osg::createWallpaper

Here is how I prepare the camera(s) for PPU: /** Setup the camera to do the render to texture */ void Cl_3Dview_osg::setupCameraForPipeline() { // setup viewer's default camera osg::Camera* camera = view->getCamera(); osg::Viewport* vp = camera->getViewport(); // create texture to

[osg-users] 2 Cameras rendering in one PBO or FBO

Hi, I'm now experimenting for a very long while and I can't get things working. I have one camera doing a statick wallpaper background and the main scene camera. When assigning camera 1 to do PRE_Render mode and setting the clear mask to just deph clearing everything looks fine on the screen. N

Re: [osg-users] 2 Cameras rendering in one PBO or FBO

Hi Sebastian, thanks for the really quick reply. cam1 is renderung a textured quad as static wallpaper and it's renderOrder is set to PRE_RENDER. cam 2 is rendering a normal scene (i.e. the cow) an its clear mask is set to just GL_DEPTH_BUFFER_BIT. This way cam2 doesn't destroy the background r

[osg-users] problems with clip node and clip planes

Hi, I have a very strange bahaviour of my scene. The following diagram shows the scene structure. On the left side the last node is the actual main scene to be displayed. As you can see there is a clip node above this node. To my understandung this should do clipping of its children. On my Linux s

[osg-users] Getting world coordinates from screen coordinates

Hi all, please give me a little assistance. I'm using geometry shaders for creating my objects during rendering. That is why I can't use the picking via lineIntersection inside osg. But I have a local proprietary structure containing my display objects and I know how to calculate the "nearest" hi

Are you sure? I think this will leed to nothing being displayed. But I didn't verify it. It is just how I understand clipping. Am 23.07.2015 um 10:35 schrieb Christian Buchner: I think you only need to flip the clipping plane around (reverse the plane's normal vector) to get the desired effec

[osg-users] Using osg::shadow with Gl 3.2 (Shader 1.5)

Due to several reasons I had to convert a project to above versions. I was successful almost all over the project due to the excellent work of osg exported uniforms etc. The last item I have to solve now is shadow. I'm using osgShadow::LightSpacePerspectiveShadowMapCB and I found out how to rep

Re: [osg-users] Qt5 integration

Hi Ricky, I understand your point of view here. But I think there are multiple use cases. If I understand your approach well you intend having a 3d rendering app with some nice qt based features. On the other hand we are developing a lot of software in the textile environment and 3d simulation o

[osg-users] Hiding shader sources

Hi all, we are using OSG with big success since many years now. Thanks Robert and the community. We are in a commercial context and we have to care about the know-how. We use Open-GL 3 and make heavy use of shaders. So my question is: Is there any way of hiding shader sources so they cannot be

Hi Pierre-Jean, I was also doing some research in that. I think the shader you adopted is not the only place where shaders have to be given. I found some place with comments like "I don't use my shader because the fixed function shaders have better performance". This is just how I remember th

[osg-users] Trouble with NodeMask and shadows

Hi! I have a little issue with a scene with shadows. I need to have within a scene that has shadows an object that doesn't cast and doesn't receive shadows. Here is what I do: constintReceivesShadowTraversalMask=0x1; constintCastsShadowTraversalMask=0x2; intmask=geode->getNodeMask()&~

Re: [osg-users] Trouble with NodeMask and shadows

Hi Pete. Thanks for your reference link. I now did it with my own shaders and of course it works. First I activated the fixed function shaders because I thought there must be some integrated mechanism for switching on and off shadows. Otherwise in my opinion the definition of receiveShadowMask does
