| The JAVA Applet |
MatHSoliD is a freeware program for exploring and constructing platonic and archimedean polyhedra. You can use MatHSoliD to manipulate polyhedral solids on the computer in a variety of ways: flattened versions of polyhedra may be printed and then cut out, folded, and taped, to produce three-dimensional models. MatHSoliD was developed with the graphical library JavaView as part of an undergraduate project sponsored by FAPESB (Santa Cruz State University, BA, Brazil).
You may use the applet offline downloading the file mathsolid.zip. The source code of the program is also available in this file. MatHSoliD supports the following languages portuguese, french, german and spanish.
