Field of View Component

by David Mans

Apr 16, 2015

This view analysis component takes a user specified visual plane, field of view angle, and distance limit to test for view obstruction from input meshes. The result is a returned percent of unobstructed views and a series of view cones with associated distanced and angles which show the extents of visibility from a given location.

    Hi David!

    Nice work! I did something similar during the workshop MIAW at Politecnico of Milan this February but using ray collision and not mesh sectioning!

    Hi man, it is awesome, I have one of definition you did several years ago, that is really heavy and uncontrollable.

    Hello, I love your work! Thanks for sharing!

    Was wondering if you have any ideas on how to operationalize this in terms of indoor views. I want to calculate the available views to the outside from the inside of a building, from specific points in each room.

    What I did so far is just assing a small line in each room, create a frame in the centre, and use that as an input. I also meshed all geometry apart from glazing in order to properly calculate views. Is this a good approach in your experience? Feels a bit messy to me :)

    Thanks!

    Kind regards,

    Theodore.

    Hi,

    This tool is really useful! Thanks.

    I have nevertheless an issue when I try to explode my mesh in order to divide in smaller pieces the field of view calculation. Could you please explain me how I could face it?

    (Instead of having one calculation by building, i use the “Mesh Explode component” from “Mesh edit” and I flatten the list of meshes. It functions for most of the angles but limits the view distance)

    Regards,

    Aymeric
