rosettes with glide reflection
For a rosette of pfold rotational symmetry you have an equivalent to the glide reflection symmetry of a fries. It is a rotation by an angle of π/p around its center together with a reflection or rather inversion at r=1. … Continue reading

Rosettes with another mirror symmetry
Symmetries are important for design because they determine the overall appearance of an image. Rotational symmetry without mirror symmetry makes a dynamical image, whereas additional mirror symmetries give a more static appearance. Generally, an image becomes more abstract if we … Continue reading

How to generate rosettes
A rosette is an image with rotational symmetry. For pfold symmetry we can use the methods of the last post “Anamorphosis and symmetries” with a simple power as a mapping function between output and input images: Here z=x+iy relates to … Continue reading

waves
I was looking at the waves resulting from stones thrown into a lake. This made me think of an anamorphosis, that simulates these troubled reflections. It is actually quite simple. The center of the coordinate system is in the middle. … Continue reading

Imitating Vasarely
The artist Vasarely is quite wellknown for his abstract geometrical designs. One of the favorites uses a square lattice with a simple design. The lattice is distorted and its cells enlarged at the center. The image then seems to bulge … Continue reading
Nautilus (2)
I can’t resist putting some of Muybridges “Animals in Motion” into the logarithmic spiral of the last post. I do similarly as in “Running in circles” and get:
Nautilus
I like Nautilus shells. They have the shape of a logarithmic spiral. This served me as a new inspiration for creating new pictures. First I found an anamorphosis that maps the logarithmic spiral onto a square lattice. I use polar … Continue reading
