Description
After I use pcl::on_nurbs::FittingSurface fit a point cloud, I want to evaluate z value of nurbs surface on certain (x,y) in the coordinate system of input cloud.
I find the ON_NurbsSurface::Evaluate interface, but it seems evaluate in normalized coordinate system.
So I hope to add a feature to evaluate in the input cloud coordinate system.

Research direction
Start by tracing pcl::on_nurbs::FittingSurface and the ON_NurbsSurface::Evaluate interface to understand how normalized surface coordinates relate to the input point-cloud coordinate system. Define the expected coordinate mapping and the public evaluation behavior, then verify that evaluating at selected input-cloud x,y positions returns the corresponding surface z values.
