algorithmic modeling for Rhino

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,

What do the output angles mean? How to convert those angles in degrees?

Thank you!

Due to issues with the download, I've uploaded the files to the forum link below for download until I find a more permanent solution.

I'm also having the same issue - does anyone have the file they can upload?

I have the same problem as Eran, I cannot download the user object =(
I have been trying to contact the provider for a few days but unsuccesfully.
Can someone share or upload the file here?
Thank you very much, will be much appreciated

I'm trying to download your sample files but unsuccessfully
is it possible for you to upload them again?
it will be much appreciated

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)

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 :)


Kind regards,

Really cool, nice animations.

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