  2. Photometry (optics) - Wikipedia

    en.wikipedia.org/wiki/Photometry_(optics)

    Luminous intensity (photometric) and radiant intensity (radiometric) In photometric quantities every wavelength is weighted according to how sensitive the human eye is to it, while radiometric quantities use unweighted absolute power. For example, the eye responds much more strongly to green light than to red, so a green source will have ...

  3. Radiometry - Wikipedia

    en.wikipedia.org/wiki/Radiometry

    Comparison of photometric and radiometric quantities. Radiometry is a set of techniques for measuring electromagnetic radiation, including visible light.Radiometric techniques in optics characterize the distribution of the radiation's power in space, as opposed to photometric techniques, which characterize the light's interaction with the human eye.

    The operating systems on which the editors can run natively (without emulation or compatibility layers), meaning which operating systems have which editors specifically coded for them (not, for example, Wings 3D for Windows running on Linux with Wine).

  6. Photometric system - Wikipedia

    en.wikipedia.org/wiki/Photometric_system

    For each photometric system a set of primary standard stars is provided. A commonly adopted standardized photometric system is the Johnson-Morgan or UBV photometric system (1953). At present, there are more than 200 photometric systems. [citation needed] Photometric systems are usually characterized according to the widths of their passbands:

  9. 3D reconstruction - Wikipedia

    en.wikipedia.org/wiki/3D_reconstruction

    3D reconstruction of the general anatomy of the right side view of a small marine slug Pseudunela viatoris. In computer vision and computer graphics, 3D reconstruction is the process of capturing the shape and appearance of real objects. This process can be accomplished either by active or passive methods.
