Monark is a creative agency specializing in the design and promotion of digital twins for architectural heritage, endangered natural sites and remarkable objects. In-between art and technology, we practice our know-how through the creation of realistic virtual sets for cinema, photography, fashion, live shows or video games. At the dawn of a dematerialized era, the concept of digital twins opens up unexpected perspectives on innovative fields. LiDAR and Photogrammetry are the accuracy techniques that allow 3D capture. We process these data and optimize it for display in real time. The digital twin is then authenticated and secured using Blockchain technology. These different steps freeze the set into a digital artwork that is impossible to duplicate, like a timeless imprint. This model is therefore geared towards sustainable development, based on the sharing and conservation of world heritage.
