Extract of the doctorate of Hervé Huitric"Contribution aux techniques de production et de traitement par ordinateur d'images digitales colorées à des fins plastiques", 1980, chapitre II, pages 118-120
The Colorix1 system had 70 x 56 pixels, the pixel is thus very visible on the image, which is a photograph of the screen. It shows an iteration of triangles colored with a continuous variation of colors.The iteration allows to vary the parameters of the triangle which is repeated: its size, its colors, its orientation. The visibility of the repetition could be accentuated or masked. From there many experiments were possible, for which the language LISP lent itself very naturally.
Example of iterations of continuous series on our first screen: Colorix1 in 1975
