These are all perl scripts that generate Geomview files. I have
provided links to the actual scripts. Because they must be run from
the command line (Unix prompt), you must save them to your own
directory and then execute them.
makemesh will create a 3D surface where z =
f(x,y). As with all the scripts, when it asks you to specify "number
of vertices", it is asking for the number of sampling points.
makecolor is an almost identical script. the difference is that the surface will have a z-based hue.
texturemesh is another similar script which will wrap a texture file around the surface.
makeparam will create a 3D surface that is
described parametrically. Make sure that you specify $i and $j as
textureparam also creates parametric surfaces, as well as wrapping a texture file around the surface.
lineartransform asks you to input a
2x2 matrix. This matrix is then used to transform a unit square. The
output will display both the transformed square and the outline of the
original. This script uses another texture
file to help illustrate the transformation.
cubetransform asks you to input a 3x3 matrix to perform a transformation on a unit cube. One corner of the cube lies on the origin and the axes are displayed in color on both the original and transformed cubes.
