MESH2D_HAND
MESH2D Applied to Hand Outline


MESH2D_HAND is a MATLAB program which reads in a set of 59 points which outline a human hand, and calls MESH2D, which is able to create a fine triangular mesh of the region outlined by the points.

The original proposer of the hand data exercise was Cleve Moler, in the textbook Numerical Computing with MATLAB.

MESH2D is a powerful and easy-to-use program, by Darren Engwirda, for creating a good quality mesh of a region when the polygonal outline of its boundary is given.

The point of this exercise is simply to emphasize that a fairly general shape region can easily be triangulated, requiring little work from the user.
