plottools[homothety] - scale PLOT and PLOT3D data structures with the same ratio
Calling Sequence
homothety(p, a, pt_2d)
homothety(q, a, pt_3d)
Parameters
p
-
plot data structure
q
plot3d data structure
a
real number
pt_2d
(optional) list of two real numbers specifying the center of the homothety (for the 2-D case)
pt_3d
(optional) list of three real numbers specifying the center of the homothety (for the 3-D case)
Description
The homothety command is a special case of the plottools[scale] command where the ratios of the scaling with respect to the axis are the same.
There are several other commands in the plottools package that transform plots, and these are listed in the plottools help page. The plots[changecoords] and plots[display] commands can also be used to transform plots.
Examples
Homothety of a stellated icosahedron
