Hi, I have created a earth database using osgdem and bluemarble data. I'm trying to insert some objects are ground level. Some questions on how to calculate the ground height are:
1. What is the easiest way to get the tile at a specific lat/lon coordinate (highest level)? 2. Once I have the tile, how do you get the MatrixTransform above each tile? 3. To get the height need to intersect (IntersectVisitor) in local coordinates of the terrain below the tiles matrix transform, correct? Any example source code illustrating this would be appreciated. Thanks Luciano _______________________________________________ osg-users mailing list [email protected] http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/
