ideal lamp simulation
Simulation of the light coming from a punctual source (imagine a microscopic star) and diffused by a surface that is a “perfect diffusor.” The lamp is at a distance of 1 unit of the center of the surface that measures 6 x 6 units. The luminance for black pixels is set at 5%, and at…

metamorphic spiral 1, black paint
CLICK ON THE PICTURE TO ZOOM! ° Visually constant perpetual geometric variation. Okay, let’s explain what I did here: the two “squares with ears” made of two regular series of parallel lines are used to precisely measure the amount of paper that a line of paint will cover. One is for the thin lines (inside,)…

B/W metamorphic spiral 1st part
CLICK TO ZOOM! I will be there for 10 days, this “spiral” will be continued later.

regular grid + random distribution (D65 #2, suite)
CLICK TO ZOOM The squared grid itself has a density of +- 0.1832 , the random distribution of black paint into its “holes” has a density of +- 0.2244 The amount of white surface not covered by the original grid being: (1 – 0.1832) removing: +- 0.2244 of white means adding again: +- 0.1832…

D65 n°2, third stage, work-in-progress
° Visual equivalences, from top to down: (1) – linear gradation between greys: Black lines, and Yellow/Violet lines – visually constant. (2) – 5 random distributions of colored lines following an increasing amount of colors (from 3 to 8) and a simulatneous increase of layers (2 pass to 7 pass), creating several geometric “patterns” (or…
