[osg-users] Server Backup
Hi all, I'm going to stop the server (www, subversion, trac...) to perform a full backup. And as Robert is on holidays this week I will try to move the current virtual machine to another server, so don't panic if the server is down. I'll keep the list informed, if anybody depends on the server write me to hold the operation. Cheers, JL. -- Jose L.

Re: [osg-users] Consistent lighting across different cameras
Just a quick guess, but are you putting rotation into your left right projection matrices? If so that's what's mucking up your lighting: http://sjbaker.org/steve/omniv/projection_abuse.html 2009/7/6 Julian Looser li...@roarmot.co.nz: Hi, I am using OSG in a multi-wall stereo rendering environment. We have three walls, and we render both a left and right eye view for each wall. To do this, in my application I create six osg::Cameras and update their projection and view matrices each frame based on head-tracking. I add the same subgraph under each camera, and I get a seamless 3D scene across the three walls. So far so good. My problem is with lighting. Although the 3D geometry is rendered in the right place, it isn't lit correctly. For example, sometimes the left view might be much brighter than the center view, which in turn is brighter than the right view. This has me confused because all six cameras are rendering the exact same scene, and the light is part of the scene (rather than a head-light of the viewer for example). My scene graph is set up basically like this (just showing three rather than six cameras). The cameras all share the same child subgraph, and just render to viewports next to each other across a window. root -- camera (mv proj for left wall) --- model --- lightsource -- camera (mv proj for center wall) --- model --- lightsource -- camera (mv proj for right wall) --- model --- lightsource I've attached a picture of the effect I'm getting. What I expected would be that the object (just a long red box) would be smoothly lit along its length. However, when it spans across my three views, you can see it's darker or lighter in each view, suggesting that the lightsource isn't in the same place within each rendering. Am I putting my lightsource in the wrong place in the scene graph? I thought it should be a sibling to what you want lit? Even though the projection and view matrices are different for each camera, the lighting should be consistent, right? I'm using a composite viewer, and each view I create I've set the lighting mode to NO_LIGHT, so I don't think it's a default light causing any trouble. The only light should be the one in my scene. If you have any ideas why this is happening I would really appreciate hearing them! :-) Thanks, Julian. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org -- http://www.ssTk.co.uk ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

(The model and lightsource are a shared graph, right?) You can place the osg::LightSource anywhere you like in the scene graph, OSG has no concept of limiting light to a certain sub-graph. With regards to the different lighting, how is your model tessellated? If it's coarsely tessellated and/or you're using face normals then the lighting calculation might only be done on the corner vertices and interpolated from there.

Re: [osg-users] Consistent lighting across different cameras
Hi Simon, Thanks for the promising link, but I don't think I'm misusing the projection matrix. I calculate the left, right, top and bottom values and set the projection matrix via osg::Camera's setProjectionMatrixAsFrustum. The view matrix is set with setViewMatrixAsLookAt using the head-tracked position and the direction towards the screen. I'm pretty sure this is the correct way to set up head-tracked stereo. The 3D effect works, just the lighting is wrong. :-( Cheers, Julian. Simon Hammett wrote: Just a quick guess, but are you putting rotation into your left right projection matrices?

Can you give more detail on the sometimes? Does that mean that the lighting varies over different runs of your software, or that the lighting is incosistent during a single run for some head positions? If the latter, it sounds like the head transformation isn't applied consistently to the light position. And is there some position for which the lighting does seem to be correct?

Hi Guys,
I've just checked in the addition of the following methods to Dragger
that enable one to control when the draggers can be activated by
clicking on them :
void setActivationModKeyMask(unsigned int mask) {
_activationModKeyMask = mask; }
unsigned int getActivationModKeyMask() const { return
_activationModKeyMask; }
void setActivationKeyEvent(int key) { _activationKeyEvent = key; }
int getActivationKeyEvent() const { return _activationKeyEvent; }
Usage looks like (from the new rev of the osgmanipulator example):
// if we don't set an activation key or mod mask then any mouse click on
// the dragger will activate it, however if do define either of
ActivationModKeyMask or
// and ActivationKeyEvent then you'll have to press either than
mod key or the specified key to
// be able to activate the dragger when you mouse click on it.
Please note the follow allows
// activation if either the ctrl key or the 'a' key is pressed and
held down.
dragger-setActivationModKeyMask(osgGA::GUIEventAdapter::MODKEY_CTRL);
dragger-setActivationKeyEvent('a');
I've added these extra controls so that we can have manipulators on
screen at the same time as being able to have the standard camera
manipulators active (i.e. the camera trackball). Previously the
example had an event handle change modes via presses to the tab key,
but this was rather awkward to use. One can still implement this
approach if you wish just by toggling the
Dragger::setHandleEvents(bool) for you own event handler.
Robert.

Re: [osg-users] VC8 build error for latest osgviewer in svn
Hello Yefei, I just did an svn update and got a buildi error with osgViewer under VC8: the file vsynctoggle_custom.h could not be found. It also used glext.h and wglext.h, There was some discussion about this earlier today, see the thread [osg-users] Build Error Windows : Application osgViewer. I think yes, it was committed with testing code by mistake. But as Chris said, Robert is on vacation this week so just go back to a previous revision in SVN and you'll be fine.

Ah, just saw the thread myself. Sorry for not reading other recent posts first. So far the old viewer with the new osg core seems to hold up fine.

[osg-users] 2.8.2-rc2 install question (UNCLASSIFIED)
Classification: UNCLASSIFIED Caveats: NONE Just built 2.8.2-rc2 on Windows Vista. The INSTALL target installs the DLLs but not the .lib files needed for linking. Is this customary?

Re: [osg-users] 2.8.2-rc2 install question (UNCLASSIFIED)
Hello Lee, Just built 2.8.2-rc2 on Windows Vista. The INSTALL target installs the DLLs but not the .lib files needed for linking. Is this customary? What's the usual approach for installing a version of OSG to link other applications against? .lib files should be in $CMAKE_INSTALL_PREFIX/lib after building the INSTALL target... It does this on my machine (VC++ 2005 SP1, Vista). Perhaps you were expecting them to be alongside the DLLs in $CMAKE_INSTALL_PREFIX/bin? If you really don't get the lib files, check the output window in VC++ when you build the INSTALL target, it will tell you where they went, or if there was some error when copying them. Hope this helps, J-S -- __ Jean-Sebastien Guayjean-sebastien.g...@cm-labs.com http://www.cm-labs.com/ http://whitestar02.webhop.org/ ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] problem with blending when using floating point FBO
Ok I was able to get it working by getting the resolved fbo using the RenderStage::getMultisampleResolveFramebufferObject method. Here a subset of my code in the draw callback: osgViewer::Renderer * renderer = static_castosgViewer::Renderer*(renderInfo.getCurrentCamera()-getRenderer()); osg::FrameBufferObject *fbo=NULL; fbo=renderer-getSceneView(0)-getRenderStage()-getMultisampleResolveFramebufferObject(); // Bind the fbo to be read fbo-apply(state,osg::FrameBufferObject::READ_FRAMEBUFFER); // Specify a color buffer as the source for the subsequent call of glReadPixel glReadBuffer(GL_COLOR_ATTACHMENT0_EXT); float* tempbuf32Bits = new float[WIDTH*HEIGHT]; glReadPixels(0, 0, WIDTH, HEIGHT, GL_RED, GL_FLOAT, tempbuf32Bits); Thanks you Jonathan ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Is there a reason you didn't just attach an osg::Texture to your camera and set the number of samples greater than 1 in the attach call? By the way, if you change OpenGL state, be careful that you restore the previous state or tell OpenSceneGraph about the changes you make (via haveAppliedMode(), haveAppliedAttribute(), etc.); otherwise OpenSceneGraph will get confused about what the current OpenGL state is. -- Bryan Thrall FlightSafety International bryan.thr...@flightsafety.com ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Consistent lighting across different cameras
Hi Ulrich, (The model and lightsource are a shared graph, right?) Yes, that's right. With regards to the different lighting, how is your model tessellated? If it's coarsely tessellated and/or you're using face normals then the lighting calculation might only be done on the corner vertices and interpolated from there. The model is a simple box with no further tessellation, and just face normals. However, the effect is the same with more complicated and higher-tessellated models. I think the detail of the model shouldn't effect the lighting in this case... all the cameras are looking at the same lit scene from the same point, just with slight offsets in the projection and view matrices. Other than possibly subtle differences in specular highlights, I wouldn't think the scene should be lit any differently in each of the views. I realise the lighting won't look great on a low-tessellated model, but I think it should be consistent. I figure it's like taking multiple photos and stitching them together into a panorama... the world doesn't get lit completely differently just because you turn left and right a bit. :-( Cheers, Julian. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Control of animated object
I m seeing the examples but look like that my problem is that I m doing the animation in 3DMAX and exporting the object in .IVE file. The object load but always in loop mode. Maybe I m not understanding something but look like that OSG have a dificulty in control of animations . I m refering about 2D movies and imported 3d objects . Excuse-me, I know that I m a little user of OSG but I have some ideas. To be perfect to me OSG would have any functions like : setFrame () -- that stop object exactly in the frame that we want . int getCurrentFrame() -- return the current frame of animation. int getNumberOfFrames() -- return the total number of frames in the animation. These kind of functions ll help a lot with movies or image sequences and 3D object animations . I always have to know when an animation ends to execute next action. Nobody had this kind of problem ?? ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] VPB
I got it to build. I kept messing with it and finally got it to work. However, I am trying to build the osgDotNet wrappers and I am having trouble there. Has anyone built these?

Re: [osg-users] osgFX render issue
Hi Vincent Well, i haven't understood your scene graph right. Let's me draw your scene graphs (1) Group == type of osgFX::xxx ___| | || | Group1Group2Group3Group4 (2) Group __| | | | | Group1== type of osgFX::xxx Group2Group3Group4 But if i am right understood your email you appended the osgFX effect not as group, instead you appended it as parent node, right? (x)Group ___|__ | || | | Group1Group2Group3Group4 osgFX ??? if i am wrong please stop reading and explain again the exacly outlook of the scene graph you have. otherwise have a look into the osgFXbrowser example. if you are using (x) this would enable the osgFX for all object under osgFX ??? (childrens) not for Group, GroupX regard adrian 2009/7/6 Vincent Bourdier vincent.bourd...@gmail.com Hi all, I've got a understandable problem with osgFX::Cartoon and osgFX::Scribe.
