Hi Yuchao,

you're feeding XYZ points into the [Eval] component. It requires UV points. You'll need to actually project your points onto the surface with the [Surface Closest Point] component. This will convert XYZ coordinates into UV coordinates, which can then be used to query Normal vector, Curvature data etc. from the surface.
