Re: [osg-users] OpenSceneGraph new website almost ready

Hi Torben, We will maintain the trac instances both osg and VPB for archiving old documentation. Anyway to migrate the VPB trac requires much less effort than the osg site does. So once the osg site is totally done we can discuss about where to place the VPB docs, maybe in the tools section or in

Re: [osg-users] Question about the correct use of osg::FrameBufferObject

Hi Frank, If you nest a Camera below another Camera it operates within the the parent Camera's RenderStage (the RenderStage is the rendering back-ends way of managing what to draw each frame), and if it's assigned as a PRE_RENDER then it'll be drawn before the main body of the context of the

Re: [osg-users] i am having problem compiling program related to TraingleFunctor

Hi Om? Prakash? Paliawl? Could you sign with your name so we know how to address you? As for you errors, it looks like you need to include osg/io_utils as this will provide the helper functions for writing Vec3's etc. to ostream. Robert. On 7 February 2013 05:01, om prakash Paliwal

HI Zeki, I don't know the specific cause of the problem but again as I don't have your problem infront of me or the able to see the problem first hand. Best I can do is stress that you need to use doubles. Go back through your original code submission, is everything doubles??? Keeping looking

Re: [osg-users] Failure in casting to osg::AnimationPathCallback*

Hi I've one run into similar issue when was compiling some sample under linux, in my case it was solved by adding -rdynamic flag to gcc, i think there are some similar option to your compiler about exporting symbols. Cheers. 07.02.2013, 08:35, "Philip Lamb" p...@eden.net.nz:Hi all, I'm running

Re: [osg-users] Failure in casting to osg::AnimationPathCallback*

Hi Robert, this is not a compiler bug, this is by design. gcc compares instances of classes by the pointer to its vtable. (Visual Studio uses a string-comparision) If you define a class in a shared library and use it in your app there are chances that you end up with two vtables of a class,

Re: [osg-users] Failure in casting to osg::AnimationPathCallback*

Hi Stephan, Thanks for the explanation, you learn something new everyday :-) Incompatibility like this I'd personally put down as a bug in the design/implementation rather than a feature. I am curious why we haven't seen this particular issue more often. If the visibility of classes is hidden

Re: [osg-users] How to acquire the screen coordinates of a 3D object?

It looks like you forgot to concatenate the window matrix from the Viewport object onto the MVPW matrix in what you call the automatic version. You also need to remove the matrix mutiply of the window matrix with the screenPosition4d object. This should not happen after the perspective divide.

Re: [osg-users] Failure in casting to osg::AnimationPathCallback*

Hi all, Thanks for the pointers to the source of the problem. Indeed it is related to symbol visibility. For reference, I had to change Xcode's default settings as follows: GCC_SYMBOLS_PRIVATE_EXTERN = NO (Setting name in Xcode is Symbols Hidden by Default)

Hi Robert, I found the problem yesterday. You are right, the problem is regarding to floating point usage. I am computing camera position using center of the object's BoundingSphere. When I start debug whole code, I figure out that the BoundingSphere type is floating point and
