Continuing my pixel bending experiments, this shader converts an image/video into coloured dots, creating a 'retro' feeling (or whatever emotions are stirred in you by the presence of a dotted grid). I tried to get a video demo, but since I have no idea how to do that in Flash, all I got you is this image preview . This shader is compatible with Flash.

Parameters

radius

Dot radius (in actuality used as diameter )

padding

Fraction of the circle radius used as padding between the dots

snap_to_pixels (boolean)

Determines if dots are to be snapped to whole pixels. Use this when anti-alias is off to produce better-looking results.

anti_alias (boolean)

Makes dots look smoother. Turn this off to produce blockier, more pixelated dots, which look better with smaller radii.

Evil Rabbit!

To get an evil-looking rabbit, pull the padding to 0, reduce radius size to about a fifth of the whole slider, and check both options. Rawr!
