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.

C++ OpenGL mesh rendering

I know there are a lot of resources about this on the internet but they didn't quite seem to help me. What I want to achieve: I am baking a mesh from data which stores the vertices inside a vector. (Vector3 is a sctruct containg float x, y,…

How to compute locations of mesh points when resolution is increased?

Suppose we have some mesh (see the illustrating picture from CorelDraw, which uses the same technique in "Mesh fill" instrument). (source: sonic.net) Obviously this kind of mesh is represented by a set of points and lines between them are actually…

Mesh triangulation and simplification C++ library

I am looking for a C++ library to triangulate and simplify 3D mesh. My 3D meshes are potentially huge (around 3 millions vertices). It should ideally be open source. Any idea?

Algorithm for smoothing edges of an open 3D mesh

I have a 3D mesh which represents a surface with some rough boundaries which I would like to smooth: I am using a half edge data structure for storing the geometry so I can easily iterate over the boundary edges, vertices and faces. I can also…

Fastest triangulation algorithm with holes?

I'm working on path finding for an RTS game, where I am building a navigation mesh from the game's grid. I have written an algorithm similar to Marching Squares which creates and simplifies the borders between the walkable and unwalkable regions of…

What are appropriate starting points for converting video on canvas to a 3d mesh

Is there currently a library in JavaScript for converting a video stream in Canvas into a 3D mesh? An example situation is to point a camera at a cup and to capture the raw imagery, comparing previous data with new data to generate an edge outline…

Distribute points on mesh according to density

Given a (possibly open) mesh with a density texture and a number of points I need to distribute these points according to the density on the mesh. So far I have made up several solutions some of which worked and others did not. One of the algorithms…
