[osg-users] animation from one projection type to the other one

Hi all, I'm trying to implement an animation from a perspective projection to an orthographic one. What I'm computing at each step is a weighted linear combination of 2 projection matrices (the start, that refers to a perspective projection, and the end, which is an orthographic projection).

[osg-users] Point attribute affecting display of triangle on OS X

Attached is a simple OSG example that, on Mac with nVidia card, seems to show point geometry with the Point StateAttribute set causing other geometry to be clipped. We did not see this on a Mac with an ATI card. This has been reproduced on the OSG trunk, but has been seen on older versions as

[osg-users] CompositeViewer and RTT-SceneGraph

Hello, I tried to render a scene into a texture and use a frame buffer object render target for the view master camera. I want to chance the camera with a CameraManipulator. It works fine if I only use one view, but it doesn't work if I use more views. The CameraManipulator get the wrong

Re: [osg-users] How to prevent resize of viewer window (WindowsandLinux)

Hi Karl, Is that you are trying to prevent the resize done by the window manager? Under X11 there is the override redirect flag to prevent the window manager taking control of the window size so you can get exactly the size you want, however, it also prevents the window manager from decorating

Re: [osg-users] Rendering without calling osgViewer::frame

I'm currently working on a project where I have to integrate library into a 3rd party application's source code. The library consists of a custom osg Camera that takes 9 snapshots of the user's scene. The headache's I've run into are the following: 1. I cannot seem to turn off the 3rd

Re: [osg-users] Rendering without calling osgViewer::frame

3. I don't know if this is related, but when adding my camera to the 3rd party app's osgViewer I am unable to change the color and depth buffer resolution. Calling setTextureSize and Camera::setViewport will seem to increase the size of the texture but the actual contents that get rendered

Hi Robert, I'm afraid I can't think of all the headline changes in 3.1, been a bit too long in coming I'm afraid - over six months since 3.0.1. Well, for one there's the new ViewDependentShadowMap which greatly improves shadow stability over the previous LightSpacePerspectiveShadowMap

Re: [osg-users] animation from one projection type to the other one

Hello Gianluca, I think, and I'm not exactly sure about it that if the matrix W component (4th column) is zero, then the computation works with the 3x3 matrix. When it is different than zero, it uses it as 4x4 matrix. Now supposed that startProj or endProj has in the 4th column zero, and the
