Re: [osg-users] Building JNI wrapper for OSGdem

Hi Sean, The first I spotted watching your stacktrace is that your are mixing debug with release libraries. AFAIK on windows mixing debug and release always gives problems, so the best you can do if you want to debug your code is build osg in debug or build your code in release with debug

[osg-users] OSG and Qt fullscreen problem

Hi, I am trying to integrate an osg viewer into a Qt user interface. To do this I am using the osg viewer widget from the OpenSceneGraph 3.0 Cookbook. If I set the widget to fullscreen with the Qt method showFullScreen(). If I do this I have a gray border around my viewport. To eliminate the

[osg-users] Manipulator and selection

Hi, I started to work with OSG last week and I have some issues. For my project, I need to navigate in a scene and select three types of objects : points, lines and surfaces. I created 3 class : surface, point and line with this kind of tree: Surface /\ Line

[osg-users] OpenSceneGraph - voxel/terrain rendering

Hi, I have been working on a minecraft world viewer for a while, and most of my work has been done in Ogre3D, as this library is what I am most familiar with. However, it is pretty clear that Ogre just can't go fast enough with my specific use case - it sets so much redundant state per batch

[osg-users] Problem with semi-transparent textures

Hi, I encounter the following issue with semi-transparent texture images: After loading a textured model from a file, I want to change the texture image into an image sequence. My code looks similar to the one of the 'osgimagesequence' example program. The texture replacement works fine and the

[osg-users] OSG with Qt fullscreen problem

Hi, I am using the code example from the book OpenSceneGraph 3 Cookbook to implement an OSG application with a Qt gui. If I set the widget which contains the viewerwideget to showFullscreen() I get a gray border around my osg scene widget. I found a solution to set the margin of the layout to

[osg-users] ProxyNodes

Re: [osg-users] Uniform arrays.

Well, adding [0] actually did the trick! Mismatch of the array sizes did not matter in the end(I want to pass arrays of variable length to glsl with sizes up to 20 elements, so that's fine with me). Not sure why my drivers don't work here, I'm on Linux with NVIDIA card and fairly up to date
