import real-time multi-mesh geometry from grasshopper to TD

Hi everyone,
I am useing the modeling tool(Rhino+Grasshopper) sending the real-time mesh data to touchdesigner. There’s a plugin bridge these two platform is gHowl (github.com/quilime/gh-td).
Here’s my working screen:

Does aynone have some ideas about why the mesh are failed from gh sending to td…?
Thanks for any kind of tutorial on this topic!!

I’m a grasshopper user. I think it’s because you are sending the point and vertex data but not the face data. (I think, sorry I am on my mobile)

If you search the TOX forum for the term grasshopper you’ll find a TOX that sends all the relevant data. But be warned it is super slow :frowning: grasshopper computes on the CPU and complex stuff can really chug.

Hi Nick,

Thanks for your reply!!
I search the term GH and read them all. I am not sure if I get your point…
Dose that TOX file hide in this post http://www.derivative.ca/Forum/viewtopic.php?f=27&t=8952&p=34628&hilit=grasshopper#p34628 or anywhere else?

And I got another question about the data type:
I thought the mesh data from grasshopper is all about vertex and vector (presented by coordinate) What does the mean “face data”? :exclamation: I must missed something obviously…

So much appreciate for your reply again!!

A really helpful way of debugging would be to look at what is actually being sent by using a sop to dat so you can see what points/prims are being sent.

If everything looks good in the dat, I’d be curious as to your render settings. It’s possible that if one of two triangles are showing up on every side that the normals are flipped on the triangle that is not showing and you have backface culling enabled.
