Re: [osg-users] [osgPlugins] png plugin - problem loading images

Hi Andrey, Most likely your osgdb_png.dll depens on a dll not in your path. It might be libpng.dll but now I am just guessing. use dependencywalker (http://www.dependencywalker.com/) http://www.dependencywalker.com/ to see what's the problem. Laurens. On 11/23/2011 6:33 PM, Andrey Ibe

[osg-users] Custom osg::NotifyHandler problems and multi-threading

Hello everyone! :] I am trying to redirect all OSG notifications to a file by creating my own notify handler class (inheriting from osg::NotifyHandler) but I get some random crushes. Mostly during run-time and sometimes when I close the application. All of them reporting some kind of heap

[osg-users] What is a good scene graph setup for post processing?

Hello, I am a little bit frustrated. I want to render my scene into a texture and map this on a plane. After that, I render the plane with an orthogonal camera. My scene use shadows (standard shadow map) and I use callbacks. My current scene graph looks like the follow example:

[osg-users] ShadowMapping in a multipass deferred setup

Hello, I have used the osg shadow implementations with great success in state of the art forward rendering. Right now I'm trying to implement shadowmapping into my deferred rendering approach. Can anyone point me into the right direction, regarding the correct usage of the view dependent

[osg-users] Single scene, multiple viewers : problem with texture

Hi, I've got a problem when viewing the same scene from two different viewers : - Viewer A with Camera A - Viewer B with Camera B I load a node with : Code: osg::ref_ptrosg::Node pNode = osgDB::readNodeFile(...); Then I do : Code: p_viewerA-setCamera(p_cameraA);

Re: [osg-users] How to create a decal on a road segment?

To demonstrate the problem here is a screenshot. [Image: http://forum.openscenegraph.org/files/ramp_segment_587.png ] The code below shows a simplified version of the problem. When you look at the same angle as shown in the screenshot, the 'lanes' (red triangles) will appear through the 'road'

Re: [osg-users] How to create a decal on a road segment?

Hi, Thanks for your answer, but unfortunately the multi-pass technique gives the same result as the stencil buffer. (I tried it, to be really sure.) Cheers Raymond. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=44073#44073 Attachments:

Re: [osg-users] How to create a decal on a road segment?

Raymond, We had a similar problem with a few, older, air field models. Luckily the polygons that represent the stripes where positioned in the models scene-graph to draw last (with respect to the model). All that was required was for us to turn off depth for the sections that needed it

[osg-users] ON_DEMAND and other windows in Qt

I am using OSG osgEarth in my Qt application. When I use ON_DEMAND, it does not always repaint when I would expect it to. The easiest way to describe this would be as follows (I have seen several variations to this, but believe they are all related): 1) Open up the application using osgEarth

[osg-users] osgViewer::GraphicsWindow::getWindowRectangle() results

I had developed some Qt code on Windows that worked great. When I compiled it on Linux, I noticed some oddities. The most interesting one is that: osgViewer::GraphicsWindow::getWindowRectangle() returns an absolute window position in Windows (x != y != 0) whereas it seems to be

Re: [osg-users] osgViewer::GraphicsWindow::getWindowRectangle() results

Thank you for your reply. I actually got around this by getting the central widget's (Qt) window rectangle instead of using the graphic window's rectangle. I agree that this seems like an inconsistency that would be nice to take care of. Incidentally, I took a quick look and did not see a

[osg-users] Full-scene blend with render to texture problems

I am encountering some problems with full-scene blending using render to texture. It appears that the blend operation is reading the main scene data as being completely blank (ie. matching the clear colour). I have already spent a fair few hours trying to solve this on my own, and I was

[osg-users] Setting modelview matrix with viewer.getCamera()-setViewMatrix(modelViewMatrix) not working

Hi, I want to set the modelview matrix with viewer.getCamera()-setViewMatrix(modelViewMatrix) like in the following code: int main(int argc, char **argv) { osgViewer::Viewer viewer; osg::Node* rootNode = createRootNode(); viewer.setSceneData(rootNode); return viewer.run(); }

Re: [osg-users] Setting modelview matrix with viewer.getCamera()-setViewMatrix(modelViewMatrix) not working

Hi, This might be your problem: If you use CameraManipulator (for example TrackballManipulator), it will overwrite your ViewMatrix every frame ... see Viewer.cpp @1040 Code: if (_cameraManipulator.valid()) { setFusionDistance( getCameraManipulator()-getFusionDistanceMode(),
