Hello Pachyderm Users,
We are going through an exciting period, including the startup of an organization to support the growth of Pachyderm, and extend the educational agenda of the project. In the next few weeks, we will be submitting our long-form 501(c)3 application, which will give us the rights of a not-for-profit organization established in the state of Connecticut. As part of the transition, we are phasing out the old website. The new site will be up in the next few weeks, and you can find it at:
 
 
We are looking forward to the next phase of this project, and we hope that you will be there with us to learn and continue to support us!
 
kind regards,

Hi Arthur,

Thank you very much sharing Pachyderm Acoustic plugin! I am looking forward to digging it, although I have not used it yet due to Rhino version issue, I guess. Does Pachyderm work with Rhino 6 as well? I have tried to install it but the error message says that it seems not compatible with Rhino 6. I could see them in Grasshopper though. Any idea?

Thanks,

Sang

Hi Authur,

Thanks so much for your reply.

Now I have already know how to save the data and read the data in gh and had no prob with NURBS scene

I would like to know what is the data to be connected to Room in Visualize Pachyderm Rays component? From the hint when I tried to connect brep to Room, I connected NURBS scene to it. It gives me the error saying 'Object reference not set to an instance of object'

Sorry for the trouble to have to explain to me step by step...

Thanks!!!

Hi Oneiric,

GL wants one integer for each piece of geometry you put into GG. This integer will be the zero-based position of the layer in the Rhino layer dialog. The layer titled 'default' generally appears first in a new document. That would be layer 0. The next layer you add would be directly below 'default' and would be layer 1, and so on.

What the scene component is looking to do is get the materials you have assigned to that layer in Pachyderm for Rhino. This is the most obvious way, perhaps that Pachyderm for Rhino and Pachyderm for Grasshopper work together. They share resources like materials.

The connection will be deepened in the future, as I develop certain other tools. Stay tuned.

Arthur

Hi Authur,

Thanks for your creation of this plug-in. 

I have read all the tutorial on the website and the comments & discussions here. I do not see how gh and rhino plugin could work together. Is there any example for me to learn more about it ?

Or may I know for NURBS Scene component, what should be plugged into GL? What is the integer id of the layer in the description?

Thank you!

Hi,I want to figure out how to use it in grasshopper, could you sent me the example file of grasshopper to my email?

hdeng@iastate.edu

Thanks very much!

Hi all,

Daniele and I have worked through the issue. It seems to me that this is not terribly clear in the website documentation, so I will say it here. Your model must be in meters for it to work correctly in Pachyderm. Maybe someday I will fix this, but for now, in order to prevent  an onslaught of bugs, please work in meters.

Rhino makes it pretty easy to fix this. I can be a little trickier in Grasshopper, but still not overly complicated.

kind regards,

Arthur

Can you send me your email to send you the project?
Or write it at rizza.d@hotmail.it
Thank you

Kind regards,

Daniele

Hi Danielle,

There are no limits, and your problem seems very different from Stracus's problem. His originated in the Scene class, and most likely had to do with his model. Yours, from your picture, occurs after running a simulation, and has to do with composing the Impulse Response.

I can't tell what is wrong with it from your picture. Please email me your files and I can have a look.

kind regards,

Arthur

Comment by Daniele Rizza on July 23, 2017 at 9:44am

Hi Arthur,

Like Stracus, when I launch my analysis, appears an error that says "Index beyond the matrix limits".
Where is it possible change these limits?

Daniele
