# tetrahedron_grid

tetrahedron_grid, a MATLAB code which generates a grid of points over the interior of a tetrahedron in 3D.

Starting with any 4 points A, B, C and D that define a tetrahedron, we can divide each edge of the tetrahedron into N subintervals, and create a tetrahedral grid. This defines ((N+1)*(N+2)*(N+3))/6 points that lie on the intersections of grid lines.

The library includes a routine which allows the user to pick an arbitrary tetrahedron and an arbitrary number of subdivisions. It then returns the tetrahedral gridpoints defined by that choice.

### Languages:

tetrahedron_grid is available in a C version and a C++ version and a FORTRAN90 version and a MATLAB version and a Python version.
