My name is Giovanni Messina and I have been an architect since 1999 and since 1997. I have been working on new systems of graphic visualization oriented towards architecture. I have many professional collaborations with institutions and universities. For about ten years I have been collaborating with studios and companies, mostly non-Italian, that use graphic engines for the restitution of architectural environments and not only, above all Unreal Engine and Cryengine. Currently I am part of an "Evolving" research group based in Trieste that deals with VR, AR, MR.
