In this work the tecnoconference company has instructed me about the 3D modeling of the auditorium at the congress palace. A magnificent Auditorium with sloping sectors, with over 1,000 seats in the stalls, with a large stage and a striking movie screen. The modeling was impressive and very impressive. Once the modeling was over, I switched to materials and rendering. This has become the main reference for renderings and simulations of events and congresses in the aforementioned space.
