triangle_interpolate, a Fortran90 code which demonstrates some simple techniques for interpolating data on a triangle.
In the most common case, the value of a quantity is known at the vertices of a triangle, and a reasonable interpolated value is desired at some point p in the interior of that triangle. This can be done by linear interpolation.

triangle_interpolate is available in a C version and a C++ version and a Fortran90 version and a MATLAB version and an Octave version and a Python version.
fem_basis, a Fortran90 code which can define basis functions for the finite element method (FEM) for any degree in an M-dimensional simplex (1D interval, 2D triangle, 3D tetrahedron, and higher dimensional generalizations.)
geometry, a Fortran90 code which performs geometric calculations in 2, 3 and N dimensional space.
triangle, a Fortran90 code which can compute properties, including angles, area, centroid, circumcircle, edge lengths, incircle, orientation, orthocenter, and quality, of a triangle in 2D.
triangle_analyze, a Fortran90 code which reads a triangle defined in a file, and uses the triangle() library to compute angles, area, centroid, circumcircle, edge lengths, incircle, orientation, orthocenter, and quality.
triangle_fekete_rule, a Fortran90 code which defines a Fekete rule for quadrature or interpolation over the interior of a triangle in 2D.
triangle_grid, a Fortran90 code which computes a grid of points over the interior of a triangle in 2D.
triangle_histogram, a Fortran90 code which computes histograms of data on the unit triangle in 2D.
