Keep in mind that when Rhino (and Google) specifies the lens focal length as 50mm, what is really going on is that they are saying that a 50mm lens specified in Rhino will show the same field of view as a camera with 35mm photographic film would show if it used a 50mm lens, which is approximately the same field of view that a human eye would see. The opposite of that is an orthogonal view, like front or side, where there is no perspective distortion at all.ĭo a google search for ‘perspective’ for more info When an image “opens up,” it means that objects farther away get smaller and you are in perspective view, just like the real world. Start in Perspective view, click on the viewport label, and select ‘Viewport Properties.’ The dialog that pops up has a field called ‘35 camera lens, Lens length = ? mm.’ Try 30 mm for a nice / slightly wide angle view. The lens length is accessed via the viewport label.
The shorter the lens, the more you increase your field of view (like a wide angle lens or fish-eye lens) You mean ‘Lens Length’ – not ‘camera length.’ The longer the lens, the more you lose perspective (like a telephoto lens) and ‘flatten’ out the view. The modeler (in Blender) told me it was achieved by setting the camera length. In the attached image below, notice that the drawing seems to open from the center to the corners.
