I'm trying to understand how I might use the rotation and/or translation controls to control something other than translating ot rotating the image. I need to knoe when tanslation_x points up or down and the same kind of thing for y and z. I really would like a scalar of 1.0 with a sign. I'm brand new to glui and been into glut/opengl for just a month but have a lot of prigramming experience. Thanks, RON C
