Visualize the tetrahedra with infinite vertices in MeshLab
I use the sample code to compute the tetrahedra for 6 vertices. The returned faces contain not only the input vertices, but infinite ones as well. This creates a problem of visualisation in MeshLab. I was wondering how I can get around this?
The…

Finding faces around a vertex in CGAL?
Not sure if the question is already answered. I am working with tethedral mesh (medit mesh) file with CGAL. I need to find out the faces around the vertices in this mesh. So it will be a vertex-face iterator. Does anyone know if CGAL has this kind…

How to find the angles of the faces of a scalene tetrahedron given lengths of edges
I'm writing a program in C to determine the apex of a tetrahedron given the given the lengths of all its edges. The tetrahedron has an equilateral base and scalene sides. In order to complete the formula, I need a way of getting the angle between a…

Convert tetrahedral mesh file into face-based file (*.obj, *.ply, etc.) for visualization
In computer graphics, it's common to use *.node and *.ele files to store tetrahedral mesh, where the former one stores 3D coordinates (x,y,z) of all the vertices and the latter one stores the indices of every tetrahedron, such as

How do I calculate the fourth vertex of a tetrahedron given the other three?
I want to calculate the fourth vertex of a regular tetrahedron. I have the coordinates
{0, 0, Sqrt[2/3] - 1/(2 Sqrt[6])}, {-(1/(2 Sqrt[3])), -(1/2), -(1/(2
Sqrt[6]))} and {-(1/(2 Sqrt[3])), 1/2, -(1/(2 Sqrt[6]))}
Can anybody please help?
