there is a rough version of a viewpoint/world controlling object. it has 2 modes, one allows you to move like in a 3d game world and the other one lets you interact like in a modelling program like maya. (I am not sure if it works on windows, though...) you interact with mouse and ctrl/alt in your gemwin. http://www.parasitaere-kapazitaeten.net/Pd/advcam if you want to do something more basic, have a look at the helpfile for gemwin. the viewing vector is * camera location (xyz). that is the position of your camera * viewing point (xyz). that is where you look at * up vector (XYZ). that will tell the camera where "up" is. think of the last one as when you are piloting an airplain that turns around its length axis. the airplain position and the viewing point postion is not enough information to tell where "up" is... by default "up vector" is 0 1 0. (pointing "upward" along the y axis). then use something like [viewpoint 0 0 10 0 0 0 0 1 0( as a message to gemwin. marius.
