People from Points is a free project, which I created just for fun. It's a generative image algorithm, coded with processing. The algorithm transforms any photo into an abstract point drawing, inspired by natural structures.
The origin points are drawn according to the brightness values of the different image areas. Further points are drawn around the origin points. Their exact positions are mixtures of randomness and the perlin noise algorithm, who generates natural looking patterns. These patterns are based on natural structures such as clouds, rivers or leaf-veins. Manipulating values like accuracy, point spacing and so on, results in completely different styles.
