In the thesis we describe how we created a reconstruction of the exhibition Space Is Out of Joint by Srečo Dragan in Unity3D. We have addressed the problem of documentation and presentation of new media art in a virtual computer generated 3D world. We describe the entire process of creating a virtual gallery. In the beginning we explain our 3D modelling procedures for the realization of selected objects, then we describe our solutions for rendered textures, properties and materials, audio settings, lighting and the use of visual effects in Unity3D. We describe the presentations, interactions and simulations for interactive installations at the exhibition and optimization techniques that we applied to ensure a smoother interaction in Unity3D.
