I think one thing that may alleviate the blending a bit is to set your texture filters to nearest neighbour ( but you will never remove this type of issue with textures and lines due to mip-maping among other things)

I searched the archives and examples and found the osgsimulation, osgspheresegment, and osgscribe examples to be very helpful. I've implemented a grid overlay (and the code is very similar to osgspheresegment). However, I'm getting some "fuzziness" to the grid lines. I've attached two screen captures. The first is the grid that I'd like to overlay. The second is the grid overlaid on the terrain using the osgSim::OverlayNode. What's happening is the grid lines are getting "fuzzy" when applied as a texture. What I'd like is the crispness of the grid as shown in the first picture to be overlaid on the terrain. Does anyone know some quick hints or explanation of why this is and what I can do to get a more crisp line on the terrain? I'm a definite newbie when it comes to textures. So, there may be something very simple here, but I've tried to do some searching on this behavior and I just can't find anything. Any help or guidance with this would be greatly appreciated. chuck _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
