SilhouetteFX is named for the art form associated with Étienne de Silhouette (July 8, 1709 – 1767). The fundamental output of a rotoscoping program is a matte which when viewed appears as a silhouette of an object to be treated in isolation of the remainder of an image. The image density of the matte determines how a compositing operation ...
When lit from the front they appear as a solid piece of fabric. When lit from the rear they become semi transparent, creating a silhouette effect. Scrims can be semi-transparent or wholly transparent depending on the fabric used and the lighting. They can be painted or not. They only create a 'silhouette effect' when designed to do so.
In addition, transparency is often an "extra" for a graphics format, and some graphics programs will ignore the transparency. Animated PNG 8-bit transparency. Raster file formats that support transparency include GIF, PNG, BMP, TIFF, TGA and JPEG 2000, through either a transparent color or an alpha channel.
Barrier-grid animation or picket-fence animation is an animation effect created by moving a striped transparent overlay across an interlaced image. The barrier-grid technique originated in the late 1890s, overlapping with the development of parallax stereography (Relièphographie) for 3D autostereograms. The technique has also been used for ...
Order-independent transparency (OIT) is a class of techniques in rasterisational computer graphics for rendering transparency in a 3D scene, ...
The Pulfrich effect is the effect that covering one eye with transparent but darkened glass can cause purely lateral motion to appear to have a depth component even though in reality it doesn't; even a completely flat scene such as one shown on a television screen can appear to exhibit some three-dimensional motion, but this is an illusion ...
Overhead projector in operation, with a transparency being flashed. A transparency, also known variously as a viewfoil or foil (from the French word "feuille" or sheet), or viewgraph, is a thin sheet of transparent flexible material, typically polyester (historically cellulose acetate), onto which figures can be drawn.
The usual result is a negative shadow image that shows variations in tone that depends upon the transparency of the objects used. Areas of the paper that have received no light appear white; those exposed for a shorter time or through transparent or semi-transparent objects appear grey, [1] while fully-exposed areas are black in the final print.
