How to set the points of the clipped surface

[Nowfal1993]

Description

for example, I have a random surface like this

if I am clipping the surface with a plane along the z axis. The results would be like this:

But how we can set the points of the clipped surface to the points of the surface(in this case the points on the plane along the z axis) with which i clipped the real surface, so that I can avoid the empty spaces in the final surface. Thanks in advance

To clarify, are you trying to fill the "holes" resulting from the clip?

When clipping 3D cells, intersection polygons are created along the clipping plane but with 2D cells like in your example, there is no way to safely fill the resulting "holes" that you see there during the clip.

There are some things we can do after the fact though

Hi, Actually not trying filling the holes. If I clip the surface at z = 10(say). Instead of void points at the clipped portion, just wanna give the value z = 10.

In effect the points of the random surface above the plane has to be shifted to the plane

So you want to use the plane to sort of “flatten” the surface down?

If your function is always an elevation, what you ask is the same as clamping the Z coordinates at 10 and clipping is not necessary.

yes. but not below the plane. only points above the plane.

Yes we can do it manaully, But my prior function is in such a way that its return a normal and centroid of the plane. But if the plane normal is not in exact z direction,, In such cases I cannot find the clipping points separtely. but I can clip the surface with the plane with certain centroid and the normal.

I hope you understand the problem with clamping

I think I do and in my opinion, it looks close to topological simplification:
