We have also added computer generated images and drawings, which allowed us to analyze the geometry of the spherical dome. They are stored at Avery Architectural and Fine Arts Library. In this paper we analyze the project of the sport facilities at Brown University, which was done by Felix Candela after forming a partnership with Cutting-Praeger, during the years 1965-1972.The original plans made by Félix Candela are included in the research paper. The work presented below is part of the results of a research project at “Universidad Politécnica de Madrid”. The study has intended to show new approaches to have new era of architecture, by taking inspiration from nature in different perspectives. This paper will focus the evolution of bioinspired design and how it manifests in built-environment through different forms and structures in evolved from nature. Biomimicry leads to imitation of living nature that is highly interdisciplinary and involves understanding the functions, structures and principles of various objects in nature that lead to inspired design, adaptation and derivation from living nature. They also learn stability and variability in natural structures are because of potential energy inside the structures. Through these attempts they are getting closure to nature structural system. They use to understand this complex system by attempt of defining it through mathematical and geometrical tools. In his first attempt they just learn from nature and use its simpler form of complex nature structural system. Human being always tries to make his own signature or presence by developing shelters and settlements. The procedure avoids the need of exporting multiple iterations -as they can be generated inside the render engine- as well as the loss of precision associated when converting NURBS to polygonal meshes in curved surfaces, using a discretization process. It has been linked with Unreal Engine, allowing to render the final project and its variations in real time and exporting the scenes to Virtual Reality. The algorithm enables to modify the geometry and introduce different iterations in Grasshopper and Houdini. The virtual reconstruction of the project has been developed using a procedural non-destructive 3D model. This is not the first project where Candela used this type of variation, however, by modifying the direction of the generators and increasing the height of the hypars, it was possible to improve the curvature of the structure and reduce the deflections that appeared in previous constructions. A parabolic discontinuity is introduced in each fragment of the surfaces, resulting in a structure formed by eight different hypars. The project presents a variation of the traditional hyperbolic-paraboloid (hypar) umbrellas widely used by Candela in Mexico during the 50s and 60s. With 9-meter cantilevers supported by a single column and a height of more than 35 meters, the inverted umbrellas designed for the Cathedral would have been the tallest ever built by Candela using this structural system. The paper presents the virtual reconstruction and analysis of the project for the Cathedral of Villahermosa in Tabasco (Mexico), designed by Félix Candela in 1960 in collaboration with Jorge Creel and Juan José Díaz.
