Hello all,
During the holliday this summer I have rediscovered some of the works of Victor Vasarely (Victor Vasarely - Wikipedia) in a quite small exhibition and when I was back to work I tried to re-engineer one of them which is, among a buch of other ones, based on a deformation of a reference repetitive picture. In fact vasarely never published anything about the maths he used to compute the deformations of his pictures, hence I found it was an occasion to test a popular method of mesh editing to see if it could approach the original rendering with (see the details of the maths in https://doi.org/10.1145/1057432.1057456).
In the attached script you can play with the value of alpha on line 4. With alpha=0.001 you have the original, undeformed picture:
and with `alpha=100’ something which is very similar (but with a different number of circles) to one of the Vasarely’s “Vegal Fel” series:
Maybe Vasarely used a computer program and the first tracers which where already available in the seventies (see Plotter - Wikipedia), but Scilab allows to get close !
