rosettes with glide reflection

For a rosette of p-fold 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 p-fold 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 well-known 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
