The square step: For each diamond in the array, set the midpoint of that diamond to be the average of the four corner points plus a random value. Each random value is multiplied by a scale constant, which decreases with each iteration by a factor of 2 −h , where h is a value between 0.0 and 1.0 (lower values produce rougher terrain).
The axes of the original frame are denoted as x, y, z and the axes of the rotated frame as X, Y, Z.The geometrical definition (sometimes referred to as static) begins by defining the line of nodes (N) as the intersection of the planes xy and XY (it can also be defined as the common perpendicular to the axes z and Z and then written as the vector product N = z × Z).
The hook or "beard", i.e. the lower portion of the axe bit extending the cutting edge below the width of the butt, provides a wide cutting surface while keeping the overall mass of the axe low. This design allows the user to grip the haft directly behind the head for planing or shaving wood and variations of this design are still in use by ...
The tabar (also called tabarzin, which means "saddle axe" [in persian], Persian: تبر) is a type of battle axe. The term tabar is used for axes originating from the Ottoman Empire, Persia, India and surrounding countries and cultures. the word tabar is also used in most Slavic languages as the word for axe [1] (e.g. Russian: топор).
Diamond's RI is responsible for its brilliance—the amount of incident light reflected back to the viewer. Also important is a diamond's dispersive power—the ability of the material to split white light into its component spectral colors—which is also relatively high, at 0.044 (as measured from the B-G interval). The flashes of spectral ...
The Honest Woodcutter, also known as Mercury and the Woodman and The Golden Axe, is one of Aesop's Fables, numbered 173 in the Perry Index. It serves as a cautionary tale on the need for cultivating honesty, even at the price of self-interest. It is also classified as Aarne-Thompson 729: The Axe falls into the Stream. [2]
Crevasse rescue (or crevasse-extraction) is a set of techniques in mountaineering where climbers use their equipment to pull a climber, who has just fallen into a crevasse, to safety. [1]
