How to put a mirron on the scene

Hi there,

I would like to create a scene where an object is reflected on a mirror and the camera captures both the object and its reflection on the mirror.
So far I experimented with the Python binding of VTK, but I could switch to C++ if needed.
I know that there is the Reflection Filter, but it does not work, because it created a mirrored copy of another object, which is fine, but the light and the shadows are not the same as if there was a mirror on the scene.
Has anyone any idea? Any help is welcome.
Thank you

You can create a second renderer, place its camera in the mirrored position of the original camera, and capture the result into an image. Then display that image in the original renderer (you can use the image as texture on a rectangle).
