An opaque substance transmits no light, and therefore reflects, scatters, or absorbs all of it. Other categories of visual appearance, related to the perception of regular or diffuse reflection and transmission of light, have been organized under the concept of cesia in an order system with three variables, including opacity, transparency and ...
When infrared light of these frequencies strikes an object, the energy is reflected or transmitted. If the object is transparent, then the light waves are passed on to neighboring atoms through the bulk of the material and re-emitted on the opposite side of the object. Such frequencies of light waves are said to be transmitted. [10] [11]
The only thing that the client can do with an object of such a type is to take its memory address, to produce an opaque pointer. If the information provided by the interface is sufficient to determine the type's size, then clients can declare variables , fields , and arrays of that type, assign their values, and possibly compare them for equality.
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 or slides), and from the epidiascope , which is capable of projecting ...

For example, final red = ( R1 + R2 ) / 2. But it cannot be applied to all color models. For example, Lab color would produce results that were surprising. An alternative model is that at every point in each element to be combined for transparency there is an associated color and opacity between 0 and 1.
For example, Google Translate has a feature that allows the user to point the camera at a sign or writing in another language and it automatically displays the same view, but with the writing in the language of your choosing. This could be possible with see-through displays as well.
