  2. Dichroism - Wikipedia

    en.wikipedia.org/wiki/Dichroism

    The second meaning of dichroic refers to the property of a material, in which light in different polarization states traveling through it experiences a different absorption coefficient; this is also known as diattenuation.

  3. Dichromacy - Wikipedia

    en.wikipedia.org/wiki/Dichromacy

    The three determining elements of a dichromatic opponent-color space are the missing color, the null-luminance plane, and the null-chrominance plane. [3] The description of the phenomena itself does not indicate the color that is impaired to the dichromat, however, it does provide enough information to identify the fundamental color space, the ...

  4. Dichromatic - Wikipedia

    en.wikipedia.org/wiki/Dichromatic

    Dichromatic may refer to: Dichromacy , a form of color-blindness in which only two light wavelengths are distinguished rather than the usual three Dichromatic, describing an optical device which splits light into two parts according to its wavelength: a form of dichroism

  5. Interference filter - Wikipedia

    en.wikipedia.org/wiki/Interference_filter

    The color transmitted by the filter exhibits a blue shift with increasing angle of incidence, see Dielectric mirror. In a dichroic mirror or filter, instead of using an oil film to produce the interference, alternating layers of optical coatings with different refractive indices are built up upon a glass substrate. The interfaces between the ...

  6. Texture mapping - Wikipedia

    en.wikipedia.org/wiki/Texture_mapping

    A texture map [5] [6] is an image applied (mapped) to the surface of a shape or polygon. [7] This may be a bitmap image or a procedural texture.They may be stored in common image file formats, referenced by 3D model formats or material definitions, and assembled into resource bundles.

  7. Dichromatism - Wikipedia

    en.wikipedia.org/wiki/Dichromatism

    The extent of dichromatism of material can be quantified by the Kreft's dichromaticity index (DI). It is defined as the difference in hue angle (Δh ab) between the colour of the sample at the dilution, where the chroma (colour saturation) is maximal and the colour of four times more diluted (or thinner) and four times more concentrated (or thicker) sample.

  9. Dichromatic symmetry - Wikipedia

    en.wikipedia.org/wiki/Dichromatic_symmetry

    There are no mirror reflection (m) operations for the dichromatic triangle, as there would be if all the smaller component triangles were coloured white. However, by introducing the anti-mirror reflection (m') operation the full dihedral D3 symmetry is restored. The six operations making up the dichromatic D3 (3m') point group are: identity (e)
