My ancestors did not evolve in the presence of computers. They left me
ill prepared for the revolution of the late 20th century and the
relentless pace of change resulting from its invention. To keep
abreast the technology I modelled geometry in one digital form or
another since '73. The computer was both opportunity and impediment
for a brain like mine that wallowed in the obvious. Practise
Grasshopper. With new tech 2 years ago I SAW the kaleidoscopic like
movement on my model when I modified an obscure parameter detailing a
texture map. Today you get to experience what I see when I close my
eyes. But why does the apparent motion of 1 cross section appear
radiative while 2 are convergent?
My artwork is an animation available on YouTube. It visualizes
octahedral symmetry using my Rotating Texture Transform. 4 red
spherical octahedra are constructed from 24 pairs of rotated &
mirrored simplexes, ABCO. One simplex contains 1 spherical
surface, ABC and three triangular segments: AOB, AOC, BOC. The
four octahedra are arranged with viewpoints oriented to the 3 axes
of symmetry of the octahedron and to the polar mid edge two-fold
symmetry of a rhombic dodecahedron. Selected surface groups are
dynamically painted with a rotating transparency field resulting
in a kaleidoscopic effect pleasing to the eye. A modified JPG:
Mandelbrot_Set-13-JULIA_ISLANDS by W. Beyer is the basis of the
transparency.
