Grasshopper 3D's Z-up system to vvvv gamma's Y-up system

Hi @ddf , thanks for pointing this out. And thanks to @bjoern for letting me know :). Yes, i really have trouble figuring it out for the XForm of the blocks. I stopped on this topic for a while cause I wanted to first fix other things. I was trying what you have come up with, but can not replicate it for the XForm i get. Did you generate those csv Values in Grasshopper? If so, how did you decompose the XForm to the rx,ry,rz values you have in the csv?
As for the other geometry its quite simple, as you already stated, both are righthanded.

You can use the c# method I posted above. It creates a matrix from the XForm.

Yes, i did, but it did not fully work. something is odd. i will have to implement it with the next update, after the workshop.

Hey @wmc , thanks for coming straight on this thread.

I found this patch in an old grasshopper forum post

there is a C# script node inside that does the trick. At least to me is working for both UE5 and vvvv
same gh file found in the grasshopper forum attached here
YawPitchRoll.zip (9.4 KB)

This is the forum link

Good luck with your workshop, I am unable to attend tomorrow but I will definitely take the course later and get in touch.

Thanks

Hey @ddf !
In the latest version (1.22) the block instances are fixed and properly transformed. Even found an additional solution to this but the real issue i had was another transformation happening somewhere else without me being aware of it cause something else was not behaving as expected. This is fixed now.
Thanks for pointing this out and your input on this!

Hey @wmc this is wonderful. I will try it soon. Thanks for this great work!
