# Questions tagged [meshing]

A mesh is, by definition, a set of points and cells, when connected to form a network. This network can have many forms of geometry and topology, as will be discussed later. Often, meshes are also called grids, and that is generally related to the intrinsic organization of the mesh and/or when those meshes are related to Finite Differences problems.

### Euler's mesh characteristic and watertightness properety of a 3d STL surface mesh [SOLVED}

I need to determine if a 3D volume triangular surface mesh (STL) represents a watertight volume or not. If I use python trimesh module it tells me if it is or it is not, but it does not tell why. It ...

### How to morph enclosed mesh according to the enclosing mesh?

I am quite new to meshing and mesh manipulation. I am working on a problem consiting of meshes $A$, $B$, and $C$. The mesh $C$ completely encloses the meshes $A$ and $B$ as shown in the attached ...

### Novel Approach to Normal Estimation in Surface Reconstruction

Not sure where to post this exactly but I am hoping to find out if my approach is in any way a novel method for estimating normals in a point cloud when performing surface reconstruction (in e.g. ball-...

### Calculate Point$3$D weights used in weighted Point$3$D average for mesh morphing

I'm trying to build a script with which i can do mesh morphing. My idea is to use a mesh and markerpoints on this mesh. Then by moving the markerpoints to deform the mesh. I've tried to this by using ...

### How to approximate a curve passing through the surface of a mesh to a curve passing through the edges of the mesh (not passing any face of the mesh)?

I have a 3D triangle mesh. A curve is found by some algorithm. The curve does not pass through the edges of the mesh. The curve intersects the edges of the mesh, the locations of which are given (P0, ...

### How to optimize a 2D triangle mesh for number of triangles?

I am currently writing a program where I have a set of points within a 2D plane that I would like to convert to a triangle mesh in such a way, that the mesh has the least number of triangles possible. ...
