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.

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!

Where can i download?

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

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

Hi,

There is no limit on the number of surfaces which can be handled, but if any of them cannot generate a render mesh, it may crash.

You will have to trouble shoot your model in order to make sure that none of the geometry is bad.

I don't understand your second question. Could you please explain?

Arthur
