3D isovists

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.

Now we want to do the same in 3D. We will use the Ladybug components. We will use the LB visibility percent. Continuer la lecture de Grasshopper, Urban Analysis, 3D Isovist →

Exporting color scale renderings from Ladybug simulations outside of Rhino after baking can be challenging as most formats tend to lose the colored information. What steps can we take to address this issue?

Grasshopper result

Bake the results from Ladybug.
