Hi Andrey, What I would do in your case, is to have two renderers and two cameras. One renderer with a fixed camera with all your circles and polygons you want to preserve in your screen and another to deal with the 3D world objects. You can attach more than one renderer to the Render Window.

The problem is not with preserving shapes and avoiding perspective deformations. I would like to fix screen size of objects, so when I increase height and width of camera frustum they will occupy the same number of pixels.
