A Virtual Reconstruction of Gaudi’s Skyscraper Hotel Attraction Using Physics-Based Simulation

Abstract

This article aims to provide a virtual reconstruction of the skyscraper Hotel Attraction based on the original documentation, which makes it possible to analyze the project and propose hypotheses regarding the contradictory information in the original drawings. The geometry of the project has been defined using a physics-based simulation, emulating Gaudí’s methodology in his models. To define the curves, a model based on weighted hanging chains has been generated, using a system with springs and particles. This method has made it possible to precisely control the catenary deformation, avoiding the definition of each curve independently in favor of a unified approach. Over 300 m tall, the Hotel Attraction would have been the tallest skyscraper in the world at the time.

Nanite as a Disruptive Technology for the Interactive Visualisation of Cultural Heritage 3D Models: A Case Study

“…The use of Nanite is not limited to the world of video games. Its use is becoming increasingly important in all kinds of projects that require real-time visualisation, such as architectural visualisations [28,29], scientific [30] or heritage ones [31], or the design of film productions [32].…”
