2D Diagrams

Through my study to better understand moires (in order to deconstruction them) I discovered that moires are what occur on the computer screen when we zoom in or out.  An interference occurs between the two sets of fine grid patterns of the scanning grid and the halftone print grid of the image being scanned.  I sought to mimic this property to see if I could develop a moire that does not exhibit the basic properties of its input.  My original moire diagram created from a series of grids of circles formed a moire with a overall circle-based pattern.  I am trying to break that output.

These diagrams were developed starting from a grid of circles made of dashed lines.  The print of this grid was scanned then printed.  I repeated this cycle 7 times until the resulting diagram started to breakdown (figure A.)


figure A

This did not give me the results I expected.  I was expecting a more distinct pattern to emerge in the form of a herringbone or grid.  The pattern that resulted in this series of diagram actually derived from the deterioration rather than the relationship between two interfering grids.  I believe this is because the original image and the resulting images were not printed through a halftone process.  The halftone printing process (used in magazines, newspapers, etc) it what would result in a more traditional moire.  I would like to try and re-do this exploration using halftone.  I will have to mimic that printing process digitally or find a way to print similar to halftone as the printers I have access to do not print this way. 

This was successful in breaking from the circles in = circles out pattern that has emerged in the other moire diagrams.

Another attempt of deconstructing the moire was to create a grid of circles and loft them diagonally.  I then cut the resulting tubes by planes similar to the plates in the 3D model.  Resulting diagram:

 

This diagram still has the problem of lack of asymmetry.  This is due to its lack of systematic inputs.
