Re: [osg-users] [forum] Help to use osgViewer in MFC

Hi Nguyen; OpenSceneGraph has multithreaded structure on drawing, culling and some kind of operation and singleThreaded structure on update traversal. So if you want to add or remove some nodes from your scene graph you should do this operation any updating operation sector. For example you can

Re: [osg-users] Aligning Coordinate Systems

Hi, OSG has a default up orientation, but that does not mean that it is fixed and inflexible. You can use whatever convention you choose. E.g. we work in a north-east-down coordinate system and just adjust OSG's manipulators so that -z is up. What is the convention used by your toolkit?

Hi Brett, Perhaps others can devine what is going wrong in your code, I'm afraid I have way too much of work backlog to go reviewing uncommented application code. If you want others to help you'll want to explain what you are trying to achieve, and what artifacts you are getting. Robert. On

Re: [osg-users] data sync between callbacks

Hi Rabbi, This is really a C++ issue, sharing data... callbacks others at the other end of the mailing list/forum don't have your code in front of them so It's next to impossible to know what you are doing wrong in your code. Could be a threading issue? Who knows? We certainly can't as

Hi Jimmy, Good to hear you've got it working. One thing to watch is whether your callback is getting the current or previous frames view matrix. The viewer camera view matrix is updated in the update traversal, so if you want to be 100% sure of getting the correct view matrix then placing the

Hi Paul, Cheers for your response, ok I missed that first time around, so it is possible, that's good, just not 100% sure on how you implemented it. One special case is in my system the transparent box is sort of a zone that the camera may move inside or outside. I need it to render properly

Hi Robert, Looking at the CompositeViewer::updateTraversal(), it seems the update callback is called before update the view matrix, which mean my slave camera is using master camera's previous view matrix. But I think it's allright in my case to have 1 frame out of sync. Just want to know if
