Incorporating mesh level properties

[asadabbas09]

Thanks for sharing your awesome work.

I'm trying to work with inputs that have the following shapes:

mesh coordinates: x, y, z
mesh level scalar parameters: e.g: A=10, B=12, C=150, D=20

I changed scalar parameters to vectors using np.full and stacked them with x, y, z vertices to make a 7 Dim input C_in

x_in = torch.stack([x,y,z, A, B, C, D]

It works fine but I was wondering if that is the right way or is there a better way to include mesh level input parameters.

Because with my current implementation I'm not sure if the network is able to capture the effects of A,B,C,D on the output and seems like a waste of computational power.

Hi, very glad to hear you are interested!

This sounds like pretty a good way to include mesh-level input parameters to me. You want them to be inputs to each of the pointwise MLPs, and this accomplishes that. The added computational cost should be small, since it only makes the first linear layer slightly larger.
