Re: [osg-users] Ref_ptr question : argument and return

Hi Thibault Thanks a lot, this will help me. I understand that the ref_ptr is not needed everywhere, but sometimes it becomes very difficult to undestand if a ref_ptr is needed or if a pointer will be sufficient or safety. Thanks for your help. Regards, Vincent. 2008/9/23 Thibault Genessay

Re: [osg-users] shared VertexBufferObject question

Hi Alex, Adding back in the lazy updating of the glVertexPointer would get you a small amount of performance, but it must have been commented out for a reason, what I don't recall as this will have been a number of years back. Commenting it back in might work, but then it might come across

Re: [osg-users] ImageStream current frame

Hi Richard, Chasing after PixelBufferObject usage will just waste your time on something that really won't lead to much benefit. What you are after is a value that the OSG doesn't at present provide, but the OSG is open source, so you can take the source extended it to do what you need to do and

Re: [osg-users] Spatial View SVI autosteroscopic display

Hi Steffen, Thanks very much for the info. It did seem to me as though finding the right place to call the API from was the key issue, so your suggestion for using Postrender-CameraCallback is very useful. I was beginning to think along the lines of implementing a

Hello, I have downloaded the 2.6 version and I'm trying to add widget components to my project. All is ok but when I pass the mouse on a 3D object of my scene, an exception occurs I use this function to start my project return osgWidget::createExample(viewer, wm, myScene-getScene()); That is

[osg-users] multi camera rendering and pick issues

Hi everyone, I have an interesting issue here: I'm building a scene this way (the following is a lua script using osgIntrospection to manipulate OSG stuff) : local root = osg.Group() root:setName(Universe) -- we want to add this root object as a scene in the current project (otherwise it will

Okay, more information on this issue I mentioned: I tested a scene where I have only two satellites (not too far away, the same size) in two different sub camera (still under the main camera): in that case, using the Test 2 implementation [treating the camera as a simple Group] gives correct

[osg-users] Extracting embedded Textures

I need to extract the embedded textures in IVE files for use in another application. osgconv is not an option. Need to do it programmatically via the API. 1. Is there any mechanism, direct or circuitous, for getting a handle on an embedded texture in an IVE file? 2. Is there any spec document

HI Frank, Just load the .ive file then use a custom NodeVisitor to traverse the scene and on encoutering StateSet on the Node and Drawables check from Texture, then the Image's attached to the Textures. There a examples of NodeVisitor all over the OSG, and even some that do searches for

Re: [osg-users] multi camera rendering and pick issues

Hello again... I did other tests, my idea was: I have a single main camera displaying a root object [an osg::Group] and this root object contains 5 or 6 osg::Camera object as direct children. And those sub cameras contain pieces of the scene I want to display. Since (I don't know why, but) using

[osg-users] Best method for screencapture in OSG?

I need to update an OSG based app that performs screen capture. The existing app used OSG 1.x and readPixels. It worked but I would like to move to 2.6+ and improve efficiency. I am looking into the alternatives, but don't currently have the target hardware. Can any give insight into the

Hello Stephen, Can any give insight into the benefits of the different means of getting a screen capture that can be transferred back to CPU/main memory? The app uses OSG to model a camera on the network and streams jpeg images at a target of 30Hz to client nodes. I don't know the details,

Thanks once again for the incredibly fast response. Up to now I've been using the OsgDotNet wrappers, so writing a Custom Visitor class means maintaining and updating the wrappers as well. At least, if I understand the solution correctly. I will of course make every effort to leverage the native
