A chalk outline, which was drawn around a person laying on the ground. A chalk outline is a temporary outline, usually of a person, drawn on the ground, usually outlining evidence at a crime scene. The outline provides context for photographs of the crime scene, and assists investigators in preserving the evidence.
Another technique similar to contour drawing is outline drawing; a division between form and the space a subject occupies. [4] All three types of drawing are considered to be gesture drawings; [4] the practice of drawing a series of bodies in still form. An outline drawing does not include the visual amusement of human sight, while a contour ...
Furthermore, camouflage traits must be both adaptable (provide a fitness gain in a given environment) and heritable (in other words, the trait must undergo positive selection). [21] Thus, studying the evolution of camouflage strategies requires an understanding of the genetic components and various ecological pressures that drive crypsis.
The word "silhouette", because it implies the outline of a form, has been used in both fashion and fitness to describe the outline shape of the body from a particular angle, as altered by clothing in fashion usage, and clothed or unclothed where fitness is concerned, (e.g. a usage applied here by the Powerhouse Museum).

In other words, the shape of a set of points is all the geometrical information that is invariant to translations, rotations, and size changes. Having the same shape is an equivalence relation , and accordingly a precise mathematical definition of the notion of shape can be given as being an equivalence class of subsets of a Euclidean space ...
