Re: [osg-users] Bizzare setViewMatrixAsLookAt behavior !!

Hi John, I'm not going to dive into trying to understand your maths, there are plenty of stuff about vector maths on the web as a resource to draw upon that could explain things much better than I could. On the OSG side you have setViewMatrixAsLookAt which is standard gluLookAt behavior, or

Re: [osg-users] Bizzare setViewMatrixAsLookAt behavior !!

John, you can compose the rotation (roll, pitch, yaw) matrices yourself or have a look at osgSim::DOFTransform documentation. Then, set the position and orientation of the camera with viewer.getCamera()-setViewMatrix(). -- Alberto ___ osg-users mailing

[osg-users] Suggestions for creating an (high res?) AVI from Linux OSG app

Greetings, We want to create an AVI movie to show from an OSG Linux app. And preferably it should be smooth in the end. Any good recipes any of you could share would be greatly appreciated. I can run it either in full screen or in a big window (uses SDL). Cheers, Ted -- Read

Hi, thanks for the changes in the PNGPlugin. It builds and works fine for me. But I have a new problem: If I select the option 'BuildQtExamples' in cmake then I get an error. Two examples, namely 'osgviewerQtWidget' and 'osgQtBrowser' are missing. I think there are two solutions: 1. Add the

Re: [osg-users] disappearing line

what graphics card? I've had this behaviour on Intel's embedded laptop chipsets with their crappy OpengGL drivers. I'm guessing it's because most games only need to render triangles and this is all the driver is really tested for. - Have you tried increasing the lineWidth? Cheers, Martin

Re: [osg-users] Example code for mouse to world coordinates

In general you need to pick a point - because a 2d mouse point is a line in 3d. But if you are showing a view form a known direction of a relatively flat object (such as a plan view of the ground) you can go direct from mouse to world. Code: bool pick(const osgGA::GUIEventAdapter

Re: [osg-users] Quad Buffered Stereo FBO

FBO's don't support double buffering either. FBO's are frame buffer that are ever directly connected to display outputs. I didn't mean literally, rather that two color buffers would get attached and used as left and right back buffers. That's quite feasible, as far as I can tell. If

Mm, there is certainly something in the way CMake generates project files for vs2010. I took the suggestion of creating projectfiles for vs2008, and load them into vs2010. Works like a charm... /A On Wed, Mar 31, 2010 at 7:07 PM, Mattias Helsing helsin...@gmail.comwrote: Hi Anders, All the
