[osg-users] FixedFunctionTechnique, lighting, and createNormalMapTexture

Hey all, >From previous posts, I understand clearly that FixedFunctionTechnique is the worst of the osgVolume techniques in terms of both speed and quality of results. However, due to some specific requirements of the application I'm trying to build (need for clipping to a bounding box, need to

Re: [osg-users] CullVisitor object not getting properly deleted

Hi Robert, The code where the static cast is failing is OSG code (openscenegraph\src\osgUtil\CullVisitor.cpp). I believe it is fairly recent code that was added just prior to the release of 3.4.0. Here is the OSG 3.5.1 version of the change…

Re: [osg-users] clamp mouse cursor / position

Hi Sebastian, I'm not an expert, but in my case I've my own class overloading osgGA::StandardManipulator. In this case, while overriding the method handleMouseMove I can call requestWarpPointer without recusiving call handleMouseMove. Is it what you are looking for? Best, Florian

Re: [osg-users] Multiples scenes

Hi Robert, The player just move to a new scene so the previous one can be discarded. By scene I wanted to mean the "root" node and all its children, and the callback, keeping only the view and the camera manipulator. In the application, the player walk along a maze (an interior scene) and when

Re: [osg-users] CullVisitor object not getting properly deleted

Hi Rick, The Object that your observer is trying to dynamic_cast<> on is in the throws of being destructed - have a look at the stack trace, I'm not surprised this fails. Try removing the use of the dynamic_cast<>, replacing it with a static_cast<>. As long as you don't dereference and just use

Re: [osg-users] CullVisitor object not getting properly deleted

Hi Your problem is weird, further I don't understand why you would have to create yourself a cullvisitor... Give us the minimum code to reproduce the error please (and use code section to keep indentation) Rick Irons wrote: > Hi all, > > I am encountering an issue with a CullVisitor object

[osg-users] CullVisitor object not getting properly deleted

Hi all, I am encountering an issue with a CullVisitor object not being properly deleted in version 3.4.0. I am encountering this issue when updating from version 3.0.1. The source of the problem is a failed Referenced to CullVisitor dynamic cast that occurs in the code below...

Re: [osg-users] Setting up travis for OSG in github

Hey John, Sorry for the late reply. I don't have any experience with travis and C++. I was thinking in setting it up in my own github fork, but probably you will do it faster than me. If you want to do it yourself let me know so we don't duplicate efforts. Thanks! 2016-05-20 17:02 GMT+02:00

Re: [osg-users] [Toward BufferObject serialization] Geometry serializer FinishedObjectReadCallback???

I surely understand that... So Would there any test set that could ensure removal of this code doesn't break anything? (I would like to submit changes I made for BufferObject and TransformFeedBack serialization but i'd rather lever any doubts about its integration first) robertosfield wrote: >

Hi Julian, Thanks for tracking down the commit. I did a quick search for related discussions on osg-users but haven't spotted anything around the right time frame (late October 2010). There is probably something in osg-submissions and osg-users that discusses this as I don't think it'll be

Re: [osg-users] Multiples scenes

Hi Florian, I can't make a specific recommendation without knowing more about what you mean by "scenes", whether they occupy the same coordinate space, whether you'll want to jump between them successive, or just move to a new scene and discard. Could you explain more about how you want your

HI, Hi, Thanks Sebastian, I also tried Code: osg::CoordinateSystemNode* csn = new osg::CoordinateSystemNode(); csn->setEllipsoidModel(new osg::EllipsoidModel()); osg::Matrixd local_frame = csn->computeLocalCoordinateFrame(ECEFpnt); //osg::Quat q = camera->getViewMatrix().getRotate();

Wojtek, Hi, Thanks! Unfortunately There is a problem with line: Code: osg::Quat q_local = local_frame_inv * q; I didn't provide actual compiling code here. I might very well be, that osg handles multiplication the other way round. Cheers Sebastian no operator found... Cheers,

Hi, You probably meant getHPRfromQuat(osg::Quat (cam->getProjectionMatrix().getRotate)), but as I know projectionMatrix has nothing to do with this angles, getVIewMatrix.getRotate() gives angles but I assume in world coordinates. Any Help? Cheers, Wojtek -- Read this topic

[osg-users] clamp mouse cursor / position

Hi, I'm trying to keep the mouse cursor in a specific area, while dragging a widget. (f.e. scrollbar, 2d stick). I cannot use requestWarpPointer, because this will recursively call my mouseDrag event. Maybe its not a good behaviour at all, but still i wonder if its possible. ... Thank you!
