Including node coordinates as node feature

[chinmay5]

Thank you for the wonderful and inspiring work. I have a question regarding generating graphs with 3D node coordinate locations. If I want to generate graphs that should also learn orientation information (in 3D space) of the underlying distribution (by means of generating raw coordinates for the nodes along with other node features), should I

1. Use the node coordinates as additional node features (these would be continuous and would be concatenated with one-hot node degree features. I imagine this might be sub-optimal, but I am not exactly sure).
2. Have it as a third component in the SDE, i.e. imagine it as the third component in a graph structure and have the SDE working with three terms.

Your insights would be extremely helpful.

Thanks, Chinmay
