Historical Paintings Get a Pixelated Update [www.thisiscolossal.com]



Intrigued by an information visualisation method called ‘treemapping’, I created an algorithm in Houdini that would do the subdivisions. The algorithm takes the original image, calculates the density of information and then subdivides it, based on a few user-controllable parameters.

The result is a mosaic of rectangles that highlight the subtle changes in the colour palette of the original. The more information there is the on the original, the more it is subdivided and thus the smaller the rectangle elements. The less information, the larger the rectangle area. You could say there is a similarity to the painters’ approach of using broader and finer strokes.

what I like in the original is that it features rectangular shapes, instead of the squares.
