An object may be not transparent either because it reflects the incoming light or because it absorbs the incoming light. Almost all solids reflect a part and absorb a part of the incoming light. When light falls onto a block of metal , it encounters atoms that are tightly packed in a regular lattice and a " sea of electrons " moving randomly ...
An opaque object is neither transparent (allowing all light to pass through) nor translucent (allowing some light to pass through). When light strikes an interface between two substances, in general, some may be reflected, some absorbed, some scattered, and the rest transmitted (also see refraction ).
A transparent object allows light to transmit or pass through. Conversely, an opaque object does not allow light to transmit through and instead reflecting or absorbing the light it receives. Most objects do not reflect or transmit light specularly and to some degree scatters the incoming light, which is called glossiness.
Magical objects such as rings, cloaks and amulets can be worn to grant the wearer permanent invisibility (or temporary invisibility until the object is taken off). Magical potions can be consumed to grant temporary or permanent invisibility. Magic spells can be cast on people or objects, usually giving temporary invisibility.
Transparency, transparence or transparent most often refer to: Transparency (optics) , transmitting light (Note: Many of the articles listed below use "transparency" metaphorically, meaning that everything is visible, nothing is hidden.)
The opaque projector, or episcope is a device which displays opaque materials by shining a bright lamp onto the object from above. The episcope must be distinguished from the diascope , which is a projector used for projecting images of transparent objects (such as films), and from the epidiascope , which is capable of projecting images of both ...
Depending on the object's distance to the paper and properties of light emitted by the light source, the object's shadows look harder (7) or softer (5). Areas of the paper that are in total shadow (6) stay white; they become grey (8) if the objects are transparent or translucent (9); areas that are fully exposed to the light (4) are blackened.
Translucent objects that are modelled using alpha-test textures will also be aliased due to alpha testing. This effect can be minimized by rendering objects with transparent textures multiple times, although this would result in a high performance reduction for scenes containing many transparent objects.
