Hi, I would like to thank you for your answers. Especially for the website Skylark , it really got me started on the subject. I will definitely search more info on the 4x4 matrix.
Now about the distances I admit that I wasn't clear :). I need the distance from the camera to the center of a given 3d model(OSG Node). For the position of the 3D model I would like to use the function getTransformationMatrix() of the node. Is it possible to use getTransformationMatrix on the camera node? Then I would use the method that Skylark suggested and my problem will be solved. As for scale, as far as I know my models are not scaled in runtime. Thank you for your time!!
