rosettes with glide reflection

Posted on February 20, 2017 by

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

Posted on February 14, 2017 by

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

Posted on February 6, 2017 by

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

Posted on May 1, 2013 by

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

Posted on April 21, 2013 by

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)

Posted on April 18, 2013 by

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

Posted on April 16, 2013 by

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 →
