Glitter : spread

Glitter is a complex attribute determined by flakes specific to modern automotive finishes. It is described by such attributes as spread, sparkles (paint texture), intensity and hue.

Fig. 2.4. Spread of glitter i.e. size of glitter patch determines variation of flakes orientation in a coating material.

Fig. 2.5. Density of sparkles determines density of flakes (on the right image, the latter is ten times larger than in the left one: 5,000 and 50,000 mm³

Fig. 2.6. Size of sparkles determines the average size of flakes; it is determined by flake area and area variation) in composition model; some sparkles on the left image are not visible because they get too small.

Fig. 2.7. Intensity of glitter is determined by flakes density times their mean area (here intensity of right image is four times smaller than in the right one).
