Questions tagged [mesh]

Do NOT use for questions about mesh-networks. Use [mesh-network] instead. A mesh is a collection of vertices, edges, and faces that defines the shape of a polyhedral object in 3D computer graphics and solid modeling.

From Wikipedia:
A polygon mesh is a collection of vertices, edges and faces that defines the shape of a polyhedral object in 3D computer graphics and solid modeling. The faces usually consist of triangles, quadrilaterals or other simple convex polygons, since this simplifies rendering, but may also be composed of more general concave polygons, or polygons with holes.

What algorithms exist for finding a bounding surface to a set of points?

Suppose you have a point cloud, and you want a surface that wraps those points to enclose them all, and wrap them fairly tightly so it intersects with the outer points in the cloud - how do you generate this wrapped surface? That is, where some or…

Triangular mesh topology

I've got a triangular mesh class which contains a list of nodes (2d in my case but that shouldn't matter) and a list of faces. Each face is a triangle and it only contains the indices into the node array. The mesh comes out of a Delaunay algorithm…

Check if a point is inside an arbitrary hexahedron

I am working on a 3D finite element code, where i face the following problem: If I take an arbitrary point (say x), how do I figure out, which element it is in? This can be simplified to: How do I check if an arbitrary point (x) lies inside or…

Blender - Why is my Mesh not moving with my rig?

I imported a .fbx model to blender and made a rig, which I want to attach to the mesh. The problem is, that, after parenting, when I rotate the bones, the mesh is not moving with it. The following links are a few screenshots to make it more clear,…

Broken Vertex Data in Mesh Class

I'm trying to implement model loading, but I'm stuck with one problem. When i try to draw a mesh (a single textured quad written by hand for test purposes) for some reason duplicated data associated with the first vertex is passed to the vertex…

Create triangular mesh from vertex coordinates

Given a set of 2d data points with coordinates x and y (left picture), is there an easy way to construct a triangular mesh on top of it (right picture)? i.e. return a list of tuples that indicates which vertices are connected. The solution is not…

Matlab: `mesh()` plot with less number of grid

Let's say data is a matrix of size 129 * 129. by using mesh(data, 'FaceColor', 'none', 'EdgeColor', 'black') we get something like We can find that the grid are quite intense. I would like to have the same figure but with less number of mesh…

How to select multiple layers in Meshlab

I have 20 layers of obj files. I want to set part of them visible while others invisible. It's not convenient to set it one by one. Is there a easy way to select multiple layers at the same time and change their visibility.
