use the Viewplatform . getLocalToVworldTransform( ) method and transform e.g. the vector (0,0,-1) the you get a vector you are looking for in 3d space. Set Capability bits to read the above mentioned transformation. regards Paul Quoc Huynh schrieb: > Hi all, > > I'm trying to retrieve a

Hi all, I'm trying to retrieve a value from the viewing platform that will tell me in which direction the viewing platform is looking. I have a viewing platform moving through a terrain, the position of the viewing platform is mapped to a 2D image of the terrain, updated with the translat
