Hi, I have GeoTIFF file with a DEM_1m_VictoriaCrater.prj:
PROJCS["Plate_Carree",GEOGCS["EQUIRECTANGULAR_CYLINDRICAL_MARS",DATUM["D_MARS", SPHEROID["MARS",3396190,0]],PRIMEM["Reference_Meridian",0],UNIT["Degree",0.017453292519943295]], PROJECTION["Plate_Carree"],PARAMETER["latitude_of_origin",0],PARAMETER["central_meridian",180], PARAMETER["false_easting",0],PARAMETER["false_northing",0],UNIT["Meter",1]] osgdem successfully generate a dem for the DEM_1m_VictoriaCrater.tif. I was wondering if osg's getWorldIntersectPoint: intersectPoint=hlist.front().getWorldIntersectPoint(); will return the intersectPoint in the Mars body frame, ie will the norm of "intersectPoint._v" be around 3396190 meters, the Mars radius? Thanks alot, Linh _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
