Grasshopper, Isovist, Urban Analysis

In this tutorial, the idea is to explore the potential of Isovist for urban analysis. Isovist is the surface or volume of space visible from a specific point. This concept has been proposed by Clifford Tandy in 1967 and then redefined by Michael Benedikt. Isovists are very useful to quantify the perception of urban spaces such as opening, closeness, and also useful to define urban envelopes. Isovists help to with non-intuitive solutions for complex problems.

In this example, we will see how to set up an environment, then use a simple Isovist System, then a more complex one with Ladybug. Then we will see a non-intuitive question: where a very high tower can be seen in a dense urban context.
