The following project was produced using POV Ray (Persistence of Vision Ray Tracer), a program that renders the code it is given. In pairs, we took building with inspired geometry and tried to recreate the form or the idea behind the geometry of the form. From there we could experiment with the geometrical options. My teammate, Gabriel Kakon, and I chose the Baha’i House of Worship in Santiago, Chile by Siamak Harari {read about it here}. The building possesses an organic symbolism from their spiritual interpretation of divine numbers. It was also an excellent choice to study in this context. Below are some of the images produced by the code which appears at the very bottom fo this post.
