GEOMETRIC // PHOTO FILTER / / /
Photo filter based on random lookup for neighbouring pixels with similar color and shading via drawing basic geometric primitives.
More About This Demo From The Author
Photo filter based on random lookup for neighbouring pixels with similar color property and applying found pixels' positions and color for shading via drawing basic geometric primitives.
Seek for the similar pixel is started from the center radially. You can set starting and ending seek distance as well range of the circle sector. Alpha is calculated according to the distance of found pixels. "Line Walk" is a special mode when line primitive repeats seek process multiple times for the same color starting again from the newly found pixel.
