Wood grain is the longitudinal arrangement of wood fibers [1] or the pattern resulting from such an arrangement. [2] R. Bruce Hoadley wrote that grain is a "confusingly versatile term" with numerous different uses, including the direction of the wood cells (e.g., straight grain, spiral grain), surface appearance or figure, growth-ring placement (e.g., vertical grain), plane of the cut (e.g ...
Adobe Photoshop generates a pseudo-random noise dither pattern on startup, with each pixel location in a 2D raster array assigned a gray value (R=G=B) and an alpha value of 1 ("on"). As the opacity of the top layer is reduced, the alpha value of some of the gray pixels is switched from 1 to 0 ("off"), with the result that image pixels ...
Bird's eye is a type of figure that occurs within several kinds of wood, most notably hard maple. It has a distinctive pattern that resembles tiny, swirling eyes disrupting the smooth lines of grain. It is somewhat reminiscent of a burl, but it is quite different: the small knots that make the burl are missing.
Graining is the art of imitating the different types of natural wood grain. It ranges from simple Clair Bois to intricate English Walnut. The panelling of the great chamber of Theobalds House in England, used by James VI and I, was decorated in "walnut tree colour" in 1618 with highlighted mouldings in black and gold. [1]
The stain accentuates the alternating flat and end grain of the wood. When the wood is sawn flat, effectively cutting off the "tops" of the "waves", the result is an alternating pattern of end grain and flat grain. As end grain naturally absorbs more stain than flat grain, staining the sawn wood accentuates the striped pattern.
In addition to the grain, quartersawn wood (particularly oak) will also often display a pattern of medullary rays, seen as subtle wavy ribbon-like patterns across the straight grain. [6] Medullary rays grow in a radial fashion in the living tree, so while flat-sawing would cut across the rays, quarter-sawing puts them on the face of the board.
Mokume-gane (木目金) is a Japanese metalworking procedure which produces a mixed-metal laminate with distinctive layered patterns; the term is also used to refer to the resulting laminate itself. The term mokume-gane translates closely to 'wood grain metal' or 'wood eye metal' and describes the way metal takes on the appearance of natural ...
The final effect varies with the figure of the wood chosen [4] and can range from extremely subtle (so that the two surfaces almost appear to be a single piece of wood), to dramatic effects with wavy grain showcased, as in high-end guitars. [5] Bookmatching is also possible with marble or other patterned stone. [6] [7]
