Re: [osg-users] Proper method for getting the screen/viewportresolution.

Hi Eric, I have a camera drawback and have some legacy OpenGL code that needs to know the size of the viewport. I've tried various combinations of Viewer-GetCamera() in the main. And the callback class does not seem to have anything that can get to the viewport. I suppose it did not work

[osg-users] enable/disable a view on a CompositeViewer having more than one view

Re: [osg-users] VPB: Non-geocentric spherical data set

HI Paul, VPB is built around working on earth data, hence the default to WGS84. You can override the size of the spheriod via --radius-equator value and --radius-polar value, a recent bug fix to VPB fixed this functionality so it should work now. It should also be possible to set the coordinate

Hi Jason, In the SVN version of the OSG there is a catch for this. FYI, the PgConfig support works from 2.4.7 on my system so you are possible just a bit unlucky. I will putting out a 2.5.1 release today once I've done some bug fixing work. Robert. On Fri, May 30, 2008 at 12:23 AM, Jason Daly

Hi Juan, You need to stop threading before you remove or add views to a CompositeViewer. i.e. viewer.stopThreading(); viewer.addView(view); viewer.startThreading(); The other thing you can do is toggle the cameras associated with the view off by setting their NodeMask to

Hi Leeten, Full screen anti-aliasing is different the line and polygon smooth modes, for these you just do stateset-setMode(GL_LINE_SMOOTH, osg::StateAttribute::ON); etc. As for full screen anti-aliasing, the advice given so far won't help you, as it only works for osgViewer based apps that use

Hi Viggo, When performance drops like this it's because you've dropped onto a software fallback path in the OpenGL driver. Exactly what formats are software vs hardware depends upon the hardware and OpenGL drivers. You'll need to check with your hardware vendors specs to see what will be

Ok, that make sense. It happens every time I render with a floating point texture. The fall in framerate does not happen when I run the OSG multi render target example using HDR. My code does however use additive blending toward the floating point texture so I bet that is what cause it to fall
