Hi, thanks, gluUnproject() works well - but I'm experiencing a funny behaviour: my GL scene is scaled into -1 ... +1 coordinates and my coordinate system marker arrows have length of 0.1. The depth winZ=0 creates a huge arrow, only the base part is visible. Changing winZ towards 1.0 shows a very exponential behaviour: the optimum values for winZ=0.9997 - its ok for my, but I'd like understand this, is this because depth is related to the perspective of my view ?
thanks again, Matthias
