# Map geometric object to the surface of a mesh

## General

The tool MapGeometryToMeshSurface adjusts the z-coordinates of geometric points from a given geometry file my_geometry.gml such that they are located on the surface of a given mesh my_mesh.vtu and returns an updated geometry file my_mapped_geometry.gml.

MW: does the tool add points if necessary?

MW: what happens, if the geometry is spreading above the boundary of the mesh or not even close to the mesh?

## Usage

MapGeometryToMeshSurface -m [my_mesh.vtu] -i [my_geometry.gml] -o [my_mapped_geometry.gml]

## Simple application example

Often, the mesh resolution and the resolution of the geometric objects like polylines are different.

MW: so, what happens then?

In the first figure such a situation is depicted. In the second figure the result of the application of the algorithm is shown.

Usage for the example:

MapGeometryToMeshSurface -m SubsurfaceMesh.vtu -i TestPolyline.gml -o TestMappedPolyline.gml
