Acoustic Raytracer - Buzz Plug-in

Update:

http://www.grasshopper3d.com/forum/topics/acoustic-raytracer-buzz-v0-2

I noticed that most of the acoustic ray tracing scripts and plug-ins out there are not working with the current version of Grasshopper. I have put together a new plug-in written in C# based on Rhinocommon/OpenNurbs.

The .zip file includes two components to be added to the Grasshopper components folder, one .3dm file with example opera house geometry, and the grasshopper definition with example inputs. It was developed on Rhino SR3 and Grasshopper 0.9.

This is a very basic implementation. I am still developing more features, and working on ways to increase the speed and efficiency. In the meantime, I welcome suggestions and bug reports.

Hello,

I have a problem with this gh definition. The Ray Tracer component doesn't work. I get this error (see the attached photo). Did you ran into this problem before? Do you know how can I make it work? I'd really need this to work...

I have rhino 5 sr3 and grasshopper 09.0061...

Thank you!

Silvia,

My first thought is that your geometry is not in the right format. It needs to be individual surfaces, not meshes or breps. If it is surfaces, try exploding it before putting it into the ray tracer.

If that doesn't work, you'll have to send me the files, and I will have a look.

Thanks for the quick reply!

Unfortunately, I don't think that's the problem, because i used your 3d file. I tried it on a simpler geometry as well, and it has the same error, even if i used only surfaces..

A quick look at the RhinoCommon source suggests that the missing property that appears in the error above wasn't introduced until SR5 [1,2].

Philip, could it be possible that the plug-in was built against a newer version of RhinoCommon than SR3?
