Deform or add specific values to the ocean spectrum sop Jan. 27, 2024, 1:11 p.m.
Hey everyone,
I need BIG waves and smaller waves on top. So the method would be to give a deformed grid in the ocean evaluate, so that it already has the big deformation. Or even do it after the ocean evaluate. But I want none of this.
Is there a way to "deform" directly the volume that comes out of the ocean spectrum SOP, adding for example values to the amplitude volume based on the deformation of a grid (with a flat grid as a rest and a deformed grid to give the amplitude bewteen the rest and the deformed grid). I tried some methods with point cloud and sampling the values to add them to the amplitude volume, but it just doesn't work (I think I just don't know enough of the process happening inside the ocean spectrum SOP anyway).
It might not sound very clear, but I just want to give my ocean spectrum a specific deformation so that I can plug it in a FLIP sim, and I don't want to do post deformatio of my sim.
I tried to do the deformation directly inside the ocean source wave tank (applying deformation to the points and the fields), but it doesn't give good results during the sim. So I just need my ocean spectrum to be deformed in the first place.
Thank you,
Tom

You mean like this ?
I don't get the same image unfortunately.

Thanks for you answer jsmack.
I was indeed using this method, but I have no idea of what to put in the "From space" and "To space" values.
