Re: [osg-users] Optimizing scene structure and geometry

Hi, Ramy I've used gDEBugger tool for rendering optimizations, it have modes that turn off some features of rendering so you can determine what impacts framerate most (like it have modes which turns off all lights(fixed pipeline vertex lighting impact), replaces all textures with 2x2

[osg-users] Accessing Shapefile (GIS) Attribute in OSG

Hi, I have loaded a number of shapefiles using the shp plugin into my scene. I am trying to display the attributes of my shapefile in a billboard. Though right now I am a little confused if I can even access the attributes of my shapefile in the OSG application Hoping for some advise..

Re: [osg-users] Accessing Shapefile (GIS) Attribute in OSG

As far as I remember, the Shape file reader only creates geometry and does not associate any attribute data with the geometry If you look at the source code your can confirm this yourself, If this is still the same then this means you will have to write a mechanism to associate the attribute

Re: [osg-users] Tonemapping, RTT, PixelDataBufferObject, GPU-CPU copy pixel value

Hi Dan, I already made tone mapping algorithms in OSG, but using OSG PPU (http://projects.tevs.eu/osgppu/), very useful for post-processing like tone mapping. Have a look here: http://www.mail-archive.com/osg-users@lists.openscenegraph.org/msg18523.html In this discussion, I speak about a

[osg-users] Setting up matrices

Hello Everyone, Well, in on of my previous threads, i was advised against using glut. But i thought of using glut temporarily and get more familiar with the other classes. So, i modified osgviewerGLUT.cpp like this, in order to get some translation and rotation. Code: // global
