Grasshopper

generative modeling for Rhino

This Grasshopper definition calculates an approximation of the space visible inside a given BRep from a specific viewpoint. This is referred to as an "Isovist." From the wikipedia entry:

A single isovist is the volume of space visible from a given point in space, together with a specification of the location of that point.

Hi Andrew,


I've modified your algorithm in a way that I could use it to create view cones. I have run into a problem thought. While testing it with smaller element, I could get it to work, but after plugin it in my bigger model (city scale) the mesh would not work anymore. If I could send you the supporting files, would you be so kind as to look into what I may be doing wrong here?

 

Thank you!
