Checking of Delaunay triangulation in 3D

One of the easy ways of checking Delaunay triangulation in 2D is to see if all the angles are acute or right angles. Do we have some kind of easy checking in 3D as well?

From a triangulation of a sphere to a 4-regular planar graph in the minimum number of topological changes?

Given a triangulation of a sphere (coming from the convex hull of some points on that sphere), I need to get to a graph with these points as the vertices, where each vertex is connected by edges to ...

Generating a Quadrilateral Finite Element Mesh Over a Solid Circular Domain

Consider a solid circular domain defined by the set $$\text{Circle}=\{(r \cos\theta, r \sin\theta)|r\in[0,1],\theta\in[0,2\pi]\}.$$ I want a simple algorithm for producing a quadrilateral finite ...

Plane clipping by cubic limits

I have a plane equation given by a point and a normal vector, for example. This plane has to lay between $xyz$ limits, $300<x<2700$, $150<y<1350$, $130<z<1370$. I want to know the ...

how to calculate wall thickness of a mesh?

based on similar questions on mesh volume, volume of a mesh can be calculated by following equation: volume = ((vec1 x vec2) . vec3) /6 where vec1, vec2, and vec3 are the vectors from origin to a ...
Suppose we have a mesh $M$ with a vertex set $V$, a facet set $F$, and an edge set $E$. For simplicity we may assume all facets are triangular. $M$ is viewed as an approximation of a parametric ...
