We are developing a Grasshopper definition that takes any potential
point of view and simulates what areas on the stage would be blocked
from view. A slider controls which seat is analyzed and Rhino's camera
orientation and location are also adjusted to the selected seat. The
definition can also be used to compare the quality of view from all of
the seats by coloring the heads according to which ones have the
clearest view versus those with the highest number of obstructions.
The other day we posted a video of another definition that we are working on that allows for an analysis grid key to be displayed along the edge of the viewport. We hope that these tools will be able to be used during the design process to give feedback about a proposed seating scheme. For more information follow the link.
