jit.gl.handle Use mouse movement to control position/rotation object requires one argument: the name of a drawing context. A named drawing context is a named instance of a jit.window, jit.pwindow, orjit.matrix object which has an instance of the jit.gl.render object associated with it. This value may also be set via the OB3D drawto attribute. When the context is being drawn to a jit.window or jit.pwindow, jit.gl.handle responds to mouse clicks and drags in the destination by generating rotate and position messages out its left outlet. When these messages are sent to 3D objects, the objects can then be rotated and moved in space using the mouse.
