The rings of power opening title - Chladni Formula

[Fajota]

Hi!

I am noob at Bifrost Graph, and I have been studying for 3 weeks.

I tried to convert this Blender Geometry Nodes tutorial ( https://youtu.be/R3C34FkF9nw ) to Bifrost Graph, but I have a error when I put the Pi node.

The Chladni Plate’s formula ist: cos(n pi x / L) cos(m pi y / L) - cos(m pi x / L) cos(n pi y / L) = 0

Worked on my side. I just added a round node to pi... but not really necessary.

ok, so a field in blnder probably is not the same as BF fields. so instead use a get point position from the plane and then do the vector to scalar and that will work.

Thank you so much for your help! What is VH compound? >_<
