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.
MESH2D_HAND is available in a MATLAB version.
CONVEX_HULL, a MATLAB program which demonstrates the computation of the convex hull of a set of 2D points.
HAND_DATA, MATLAB programs which carry out some numerical exercises based on data that came from tracing several points on a person's hand.
MAPLE_AREA, a MATLAB library which takes the list of pixels that form the boundary of the image of a maple leaf within a picture, and uses grid, Monte Carlo, and Quasi Monte Carlo sampling to estimate the area of the leaf.
MAPLE_BOUNDARY, a MATLAB library which reads an image of a maple leaf and extracts the list of pixels that form the boundary.
MESH2D, a MATLAB library which can automatically create a triangular mesh for a given polygonal region, by Darren Engwirda.
MESH2D_WRITE, a MATLAB program which demonstrates how MESH2D node and element data can be written to files.
POLYGON, a dataset directory which contains examples of polygons.
TRIANGULATE, a MATLAB program which triangulates a polygonal region.
