Hello, Im writing an export plug-in for a terrain modeling application. Ive been browsing the OSG documentation and examples in the last days but I still have some uncertainties. First of, whats the best way to construct the terrain scene graph? For now Ive been using osg::Geometry and Drawables to create generic geometry surfaces to represent the terrain zones. Ive saw that there is also a osgTerrain but is this only for terrain generation or can it be used to keep and render the terrain data, too? To be noted that the terrain is made of multiple zones with multiple layers of textures and also LOD must be implemented (and maybe some paging mechanism).
And another question, if I am to represent the terrain thru normal geometry how do I encode multiple layers of textures (using multi-textures and multi-pass if necessary)? How can I use the same osg::Geometry but with different render states and textures? Thanks, Licu ____________________________________________________________________________________ Never miss an email again! Yahoo!
