Animated drawings rendered by genetic programming

Abstract

We describe an approach to generating animations of drawings that start as a random collection of strokes and gradually resolve into a recognizable subject. The strokes are represented as tree based genetic programs. An animation is generated by rendering the best individual in a generation as a frame of a movie. The resulting animations have an engaging characteristic in which the target slowly emerges from a random set of strokes. We have generated two qualitatively different kinds of animations, ones that use grey level straight line strokes and ones that use binary Bezier curve stokes. Around 100,000 generations are needed to generate engaging animations. Population sizes of 2 and 4 give the best convergence behaviour. Convergence can be accelerated by using information from the target in drawing a stroke. Our approach provides a large range of creative opportunities for artists. Artists have control over choice of target and the various stroke parameters.

An artist's experience in using an evolutionary algorithm to produce an animated artwork

“…This can range from several hundred to several hundred thousand. More details of explorations of genetic representations for this problem can be found in Barile et al (2009). There are a number of parameters which control the evolutionary and drawing processes.…”

“…This paper describes the construction of an artwork using a software system for evolutionary art (Barile et al, 2009) based on genetic programming (Koza, 1992;Langdon et al, 2008). The artwork, 'Can't see the forest', consists of a grid of animated drawings of trees created by using a software program we call 'The Shroud' (after the Shroud of Turin), for its capacity to produce a sort of ghost-like rendering or trace of a target image.…”

Image-Guided Voronoi Aesthetic Patterns with an Uncertainty Algorithm Based on Cloud Model

“…Computational aesthetics is a major unsolved problem in computer science and engineering [1,2]. Over the last decade, there has been increasing interest in using computational intelligence approaches to solve this problem [3][4][5][6][7][8]. Of those, tessellation-based Voronoi art is an important technique and can be widely applied in various fields, that is, architecture, jewellery design, fashion design, and so forth, and Voronoi diagram plays a key role in its preprocessing [9].…”

Animations rendered by braitenberg vehicles

“…One of the goals of non-photorealistic rendering [1,8,10] has been to create abstract pictorial styles. Our motivation is to provide artists with opportunities to generate visual art in a manner that is engaging, yet beyond the scope of their traditional drawing tools.…”

“…Images are generated as aggregations of simple line strokes [1,7,9]. End users can pause the system at any time and adjust agent character-Copyright is held by the author/owner(s).…”
