Hi all, I'm trying to figure out how to control the camera lens in Gem. i.e. go from normal view to 'ortho' gradually, or still, change focal length form 18mm to 55mm... http://en.wikipedia.org/wiki/Focal_length I've been playing around with 'view', 'perspec' to gemwin, and also tried changing an object's size and distance simulatneously to achieve this, but it seems that the perspective deformation always stays the same... any ideas? thanks Tim
Hello Tim,
Have a look at this patch. Is it what you asked ? ++

me again, changing the 'lens' parameter introduces a wierd flickering. I have a cube and a light, and it looks like the light seems to flip off and on at each new value. (it doesn't occur after 'lighting 0') Also, (I still don't really understand how perspec and view work) the cube gets truncated at some settings. I suppose it has to do with 'perspec' changing the distance at which objects disappear... gr, Tim
