Re: [osg-users] Multisampling

Hi, Well, the best solution in this case is recreating context without MSAA. How do I do that ? Thank you! Cheers, Filip -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=52629#52629 ___ osg-users

[osg-users] transparency issue when reading svg files through svg plugin

Hi all, I'm having this issue when reading an SVG file using the OSG svg plugin: the alpha values in the osg::image created by the plugin seem all wrong. RGB values instead are all correct. Is this a known issue? Any idea how to fix it? Did I miss some optional flag to the reader? Thanks

[osg-users] Update qglWidget size but not graphicsContext traits size

Hi, I'm trying to take a screenshot from osg render into qt windget. For this I create a class inherit from osg::Camera::DrawCallback, so when the frame is rendered the application call the virtual void operator () (osg::RenderInfo renderInfo) const function of that class. The problem comes

[osg-users] Beginner's Help: Problem setting up a shadowed scene

Hi, I'm trying to set up an interior scene by using the model of Sibenik Cathedral, then filling it with 8 lights and shadows, but my efforts fall rather short so far. Without shadows the scene looks pretty much like everything is set up alright, but when I enable ShadowMap technique, not only

[osg-users] Disabling shaders on LightPointNodes

Hi gang, I've got a setup where I have an osg::Program attached near the top of my scene graph to do lighting effects. It works great, except that LightPointNodes don't show up when it's active. I tried intercepting the LightPointNodes in the graph inside a cull visitor, and disabling the shader

Re: [osg-users] Beginner's Help: Problem setting up a shadowed scene

Hi, just a guess: looks like with shadows - black parts are the ones which does not have diffuse texture assigned and shadow technique you are using might require it to work correctly. Cheers, Sergey -- Read this topic online here:

[osg-users] Intersecting against a billboard

Hello, I have the same problem like here from 2007 : http://www.mail-archive.com/osg-users@openscenegraph.net/msg14346.html I also have this problem at the moment because i change the position of the drawables in my Billboard. So, is there a solution available ? Cheers, David

Re: [osg-users] Disabling shaders on LightPointNodes

Hi Frank, Did you set up your top-level program with ss-setAttributeAndModes(topLevelProgram, osg::StateAttribute::ON | osg::StateAttribute::OVERRIDE); ? Also, I don't really understand if you are trying to render them with fixed function pipeline or your own custom shader. For fixed

Re: [osg-users] Disabling shaders on LightPointNodes

Hi Frank, Could be something entirely different but have you tried setting empty program (= activating fixed pipeline) with default ON attribute ? ie: ss-setAttribute(new osg::Program); We were using that approach to turn off Shaders in LightPoints. Cheers, Wojtek Lewandowski 2013/2/13

Re: [osg-users] Disabling shaders on LightPointNodes

Hi The thing is osg::StateAttributes can not be turned ON or OFF with flags like that, if you have attribute in stateset it always ON (if you look at source, StateSet even dont save ON-OFF flags for state attributes, only PROTECTED and OVERRIDE bits). You can control if they have any effect with

Re: [osg-users] Update qglWidget size but not graphicsContext traits size

Hi Aitor, I'm not the author of QGLWidget so will pass on the specifics on it's implementation. One thing you could try is getting the current Camera from the RenderInfo object and then access this Camera's Viewport to get the dimensions. Robert. On 13 February 2013 13:40, Aitor Ardanza

Okay, so if I set just one LightSource, what else do I have to do in order to make the shadow work just fine without the walls going all black? Find some diffuse texture for the model? -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=52647#52647

Re: [osg-users] Beginner's Help: Problem setting up a shadowed scene

Hi, i'm pretty sure that there are shadow technique implementations that work on models without textures, you should look shadows related osg examples and check related classes interfaces/implementations to get better grip on these things. Or wait for another answer :) Cheers, Sergey

[osg-users] osgManipulator::TrackballDragger geometry of size of bounding sphere

Hi, I have realized the osgManipulator::TrackballDragger source code creates a sphere of radius 1.0. My question is if there's any way to make the dragger's geometry scales up to the bounding sphere of the model being dragged, since to my point of view, there is no such way of doing this with

Hi all -- Primarily Tim Moore... The code comments for osgUtil::IndexMeshVisitor reads as follows: // Convert geometry that uses DrawArrays to DrawElements i.e., // construct a real mesh. This removes duplicate vertices. However, if a PrimitiveSet is already indexed (i.e., DrawElementsUInt),

 Hi Looks ok to meas it written in comment, code converts DrawArrays to DrawElements, and if primitive set is already indexed it is not DrawArrays any more, and there should not be duplicate vertices in first place (besides ones with same vertex position but different other vertex attributes like
