Hi, The popping is the effect of an abrupt change from one LOD to another. The typical solution is to "geomorph" the terrain over several frames with the LOD change. It smooths out the transition so that LOD changes are subtle.
High end visual IGs have been doing geomorphing a long time with terrain skins. With the advent of shader technology, this technique is making its way into the standard desktop PCs. As others have pointed out, its complicated but it can be done. Here's an interesting article on it that may shed light on the problem and how to address it. http://www.gamedev.net/page/resources/_/technical/graphics-programming-and-theory/terrain-geomorphing-in-the-vertex-shader-r1936 -Shayne ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=47273#47273 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
