Re: [osg-users] Translate problem

Hi Sujan, viewerWid-getView()-getCamera()-setViewMatrix(::osg::Matrix::translate(1000.5, 0.0, 0.0)); this code is wrong. Also, you have attached TrackballCameraManipulator so it will fight you against the translation you do. If you want to translate an object in the scene, then use

Dear Nick thanks a lot for your code snippet. I appreciate it. I am after custom mouse event handling, I dont want TrackBallManipulator as I am more interested to manage events from Qt. On Thu, May 9, 2013 at 2:35 PM, Trajce Nikolov NICK trajce.nikolov.n...@gmail.com wrote: Hi Sujan,

[osg-users] Pan in OSG QT

I am trying to implement my own pan functionality in osg scene using Qt. Please tell me if it is right ?.But it's not happening. Check my snippet. void CSGraphicsView::mousePressEvent(QMouseEvent *e) { lastPos = e-pos(); } void CSGraphicsView::mouseMoveEvent(QMouseEvent *e) { float dx =

Hi Braden, I can't see a way for us to directly help you as the problem is in your own code, the code snippet your've provided doesn't appear to tally with the error message you've reported so we are really far more in the dark than you. The only thing I can say is that in general it should be

Re: [osg-users] PointSprite Texture orientation

Hi Daniel, For the osgParticle::PreciptiationEffect I used quads rather than point sprites as point sprites are just appropriate for circular points or cases where it's OK for the texture to be screen aligned. With modern graphics cards I'd just pass a point to the vertex shader and have a

Re: [osg-users] OcclusionQueryNode and Depth Splitting

Hi Pablo, You are the first person to report trying to combine z portioning and occlusion query, so while it might be possible you might be the first to try :-) The only way I can think of it working would be to doing the occlusion query work per partition, as the occlusion query has to be in

[osg-users] Some OSG Windows functionality not available in Linux?

Hi, Posting this on behalf of a colleague: I have built OSG3.0.1 in /usr/local directory. But I found that few of the files were missing in /usr/local/include/osgShadow directory which are already there in the windows equivalent. NOTE: - I have a windows based application (contains OSG and

Re: [osg-users] Some OSG Windows functionality not available in Linux?

Hi Nav, The OSG is almost indendtical for all platforms and your certainly shouldn't see any differences in osgShadow which has no platform specific files or features. The question has to be how did you end up with different versions of the OSG on Windows vs Linux, only you can answer this one.

[osg-users] for PAN problem

I am trying to pan my model pls check the code snippet below. viewer = composite view. getTransform() will return a osg::PositionAttitudeTransform list. But my object is moving in z direction as well inwards outwards. What am I doing wrong please help. Thanks Sujan void CSGraphicsView::pan( float

Re: [osg-users] Some OSG Windows functionality not available in Linux?

Oh thanks for that. He checked and saw that the Linux version was 3.0.1 and the windows version was 3.1.4. I guess he got one of the nightly builds, because 3.0.1 is the latest stable release. Nav or Joseph? You can call me Nav :-) -- Read this topic

Hi Sujan, what are you trying to do with your 'pan'? To move an object, or to move the camera (view) ? Nick On Thu, May 9, 2013 at 1:03 PM, Sujan Dasmahapatra sujan.dasmahapa...@gmail.com wrote: I am trying to pan my model pls check the code snippet below. viewer = composite view.

Hi Sujan, here is how I would do it: //Let load the model: osg::Node* model = osgDB:: readFile(); // Create MatrixTransform on top of it osg::MatrixTransform* mxt = new osg::MatrixTransform; // create the scene mxt-addChild(model); viewer-setSceneData(mxt); Now, having it like this, by

Re: [osg-users] OcclusionQueryNode and Depth Splitting

Yes Robert, but the main problem is that many times an occlusor will be in a different partition than the occluded object. And thats the main problem I think.. Objects in different distant partitions will be culled out by the current partition I can´t think of anything.. I thought about

Re: [osg-users] OcclusionQueryNode and Depth Splitting

Hi Pablo, I can't think of way of having occluder set up in different depth range to the objects it's being occluded with jump through hoops with shaders that would unify the depth used in the test to the same range. This is really down to handle though, you are so off the map of what is

[osg-users] osgParticle::ExplosionEffect: assistance needed

I have been exploring osgParticle::ExplosionEffect for use with our software and have run into a few things I haven't yet been able to figure out. 1) We use the Qt resource system to compile and link into our executable some of the binary resources we need, including some images. I have used

Hi, This post was really helpful for me but I still couldn't add points on the fly either. A few edits made it happen so I'm attaching my M_OSG_line_strip class. To use the class I have the following in my CreateScene() Code: osg::Vec3Array* line_pts = new osg::Vec3Array;
