Re: [osg-users] osgvolume opacity settings

Hi Robert, I think my problem is related to AlphaFuncProperty and SampleDensityProperty settings. From your previously explanation for the function AlphaFuncProperty , TransparencyProperty and SampleDensityProperty. - AlphaFuncProperty is equivalent to glAlphaFunc and sets the alpha value be

[osg-users] OSG runtime error on Visual Studio Debug mode

Hi, I am using osg version 3.0.1 with MS Visual Studio 2008. My application is embedded osg viewer to display sample, so it is not necessary to build my application with using debug version of osg. The application build settings is using all non-debug osg libraries even on "Debug" or "Rele

Re: [osg-users] Segmentation fault when I try to assign MatrixD

Just for some clarification are you trying to make a camera that follows your car model? Because I had the similar issue recently and through my research I found I could attach a camera manipulator to a node and the camera will be translated relative to the position of the PositionAttitudeTrans

Re: [osg-users] bug in Imagef::readImageFromCurrentTexture

Hi Alex, I guess this will be something that is rather driver dependant - and why I had spotted this issue with my own usage. Could you modified Image.cpp to get things working for and post the full modified file to osg-submissions. Thanks, Robert. On 15 February 2012 16:35, Pecoraro, Alexander

[osg-users] bug in Imagef::readImageFromCurrentTexture

I was trying to use osg::Image::readImageFromCurrentTexture() to read back a texture from the GPU. The glGetTexImage() call was failing because it was using an invalid pixel format. The pixel format that it uses comes from calling osg::Image::computePixelFormat() with the internal format of the

Re: [osg-users] FrameStamp on viewer's GUIEventHandler

Hi Robert, cool, I was afraid there was a specific reason not to pass the visitor to those handlers... I've submitted the patch. Also, while checking the event handling related code, let me remind you that some people found in the past that cameras sometimes receive twice the same event: https://

Re: [osg-users] Missing parts of 3rdParty_VC10_x86_x64.zip

Hi Brad, Thank you for the binaries. Now that I have things figured out a little better, I don't see anything additions or changes that need to be made. Everything compiles and runs fine, and, as a bonus, I was able to leave a couple DLLs out of my installer when building with VS2010. -- Terry We

[osg-users] FrameStamp on viewer's GUIEventHandler

Hi All, while checking the code related to event handling, I've noticed that node callbacks receives a NodeVisitor in their handle() callback, and can then extract the frameStamp if needed. The same does not apply to the GUIEventHandler added directly to the osgViewer classes, as thy are invoked

[osg-users] Segmentation fault when I try to assign MatrixD

Hello, I have a class (Car) which extends|osg::PositionAttitudeTransform|. Now I want to create camera which has the same position. So I get car's matrix in Camera's getMatrix() method: |matrix= car->asMatrixTransform()->getMatrix(); // osg::Matrixd* matrix| At this point I get stack overfl
