For many days I am thinking about real-time reflections, how it is done!
I am not talking about tricks like environment mapping or even
multi-pass rendering in IR. There are real-time reflections
implementations in some products. One of them is by Clarus. The
reflections on the car body and the reflective flooring is not due to
environment mapping as it is dynamic. Meaning if you introduce any new
geometry in the scene, it gets reflected. It is also not due to
multi-pass rendering as there are too many reflecting surfaces and hence
can not be done by multi-pass rendering.
I searched a lot about this, even I have my own ideas about it. One of
the idea is doing single-pass per-vertex raytracing in the scene. I just
wonder is this sufficiently fast so that it can be done in real-time.
Thank a lot
