TexRD is a useful application that allows animated random textures to be generated by means of algorithms based on reaction-diffusion principle.More specifically, complex chemical reactions between several fluidsare simulated and produce various patterns by self-organization.Similar morphogenesis phenomena (spontaneous build-up of shapes) areobserved in the real life and could account for the patterns observedon the skin on some animals, exotic fishes, shells, minerals...Even if it looks complicated to you, it is not necessary tounderstand how it exactly works to use TexRD ! You can take theadvantage of the software by simply starting the calculation of themanifold given examples. Progressively, you will learn how to changesimple parameters like the image size or its colors. Any texture generated by TexRD can be tiled, i.e. juxtaposingthe same basic texture so as to fill a given space. The texture willbe perfectly adjusted to each other, edge to edge without join. Webpages backgrounds can also use pattern tiling. TexRD is designed for graphic designers, cyber-artists, etc...Like a mathematical game, it showed also be of interest for sciencelovers as a powerful tool to create new original textures. The thrillof discovery is enhanced by the fact that reaction-diffusion patternscannot be predicted by the theory (except for the simplest models).They require multiple trials associating chance, observations andattempts to find the rules governing the effects of the variousparameters. You will discover completely novel textures, becausethere are so many combinations possible. With TexRD, you will be able to create all kinds of abstractimages for postal cards or front pages, bindings, paper bookmarks,windows wallpapers, as well as new ideas for decoration patterns.Computer graphics experts could also use such textures to covervirtual objects and make them look more realistic - real world isfull of random patterns!
