Dither Node

This proposed node would take the output of "ImgSample" node and process the z values into a boolean (1s & 0s) stream , so that the density of 1s in sequence would range from lowest values to highest values. (ie black would be repetitions of 0s, and white would be repetitions of 1s, while greys would be patterned sequences of various combinations of 1s and 0s)

The result would be the conversion of a greyscale image to a series points on the canvas similar to the arrangement of pixels from a photoshop greyscale conversion to bitmap with diffusion dither.



Alternatively, the node could have pointAeeay input and output, extracting the z-values internally.

There are a number of resources online about dithering algorithms, eg: http://www.tannerhelland.com/4660/dithering-eleven-algorithms-source-code/

& of course Codetrain:

I have been dithering in photoShop then importing into "ImgSampler" node to achieve a similar result, but I would be great if this process could be done directly in NE, giving ultimate control on end result.

Have a great weekend
