To get this kind of information, try ou GDAL (http://www.gdal.org). This is what gzbuilder uses internally.

OpenGL and ODE use trimeshes (meshes based on set of triangles). To reduce the memory taken by the structure, you can specify them as a set of vertices and a set of indexes. Then, in the index set, each consecutive 3-index tuple is the index of each corner of one triangle. > Also, I am using SDTS format of DEM so if anyone knows any other way of > converting this format to something that would be easy to represent as > (X,Y,Z) please let me know. There are ASCII-based DEM formats (sorry, don't know them), so you can even try gdal_translate to convert your SDTS dem into a readable format. Note that gzbuilder modifies the DEM to fit gazebo's needs. So, it may not be a good idea to base yourself on it to do what you're doing. -- Sylvain Joyeux http://www.laas.fr/~sjoyeux ========================================================== PhD student, Robotics and Interactions group, LAAS/CNRS 7 Av. du Colonel Roche 31077 Toulouse Cedex 4 Tel: +33 (0)5 61 33 64 51 ========================================================== ------------------------------------------------------------------------- Take Surveys.
