  2. Shadow mapping - Wikipedia

    en.wikipedia.org/wiki/Shadow_mapping

    The first step is to find the coordinates of the object as seen from the light, as a 3D object only uses 2D coordinates with axis X and Y to represent its geometric shape on screen, these vertex coordinates will match up with the corresponding edges of the shadow parts within the shadow map (depth map) itself. The second step is the depth test ...

  3. Template:Color temperature white points - Wikipedia

    en.wikipedia.org/wiki/Template:Color_temperature...

    A list of standardized illuminants, their CIE chromaticity coordinates (x,y) of a perfectly reflecting (or transmitting) diffuser, and their correlated color temperatures (CCTs) are given below. The CIE chromaticity coordinates are given for both the 2 degree field of view (1931) and the 10 degree field of view (1964). [1]

    en.wikipedia.org/wiki/Standard_illuminant

    A standard illuminant is a theoretical source of visible light with a spectral ... (109.85, 100.00, 35.58), and the chromaticity coordinates using the standard ...

  5. Ray tracing (graphics) - Wikipedia

    en.wikipedia.org/wiki/Ray_tracing_(graphics)

    Photon mapping is another method that uses both light-based and eye-based ray tracing; in an initial pass, energetic photons are traced along rays from the light source so as to compute an estimate of radiant flux as a function of 3-dimensional space (the eponymous photon map itself). In a subsequent pass, rays are traced from the eye into the ...

  6. List of nearest bright stars - Wikipedia

    en.wikipedia.org/wiki/List_of_nearest_bright_stars

    Prominent stars in the neighborhood of the Sun (center) This list of nearest bright stars is a table of stars found within 15 parsecs (48.9 light-years) of the nearest star, the Sun, that have an absolute magnitude of +8.5 or brighter, which is approximately comparable to a listing of stars more luminous than a red dwarf.

  7. Parallax mapping - Wikipedia

    en.wikipedia.org/wiki/Parallax_mapping

    The idea is to walk along a ray that has entered the heightfield's volume, finding the intersection point of the ray with the heightfield. This closest intersection is what part of the heightfield is truly visible. Relief mapping and parallax occlusion mapping are other common names for these techniques.

  8. Normal mapping - Wikipedia

    en.wikipedia.org/wiki/Normal_mapping

    Each channel in the bitmap corresponds to a spatial dimension (X, Y and Z). These spatial dimensions are relative to a constant coordinate system for object-space normal maps, or to a smoothly varying coordinate system (based on the derivatives of position with respect to texture coordinates) in the case of tangent-space normal maps.

  9. Messier 106 - Wikipedia

    en.wikipedia.org/wiki/Messier_106

    Messier 106 (also known as NGC 4258) is an intermediate spiral galaxy in the constellation Canes Venatici.It was discovered by Pierre Méchain in 1781. M106 is at a distance of about 22 to 25 million light-years away from Earth.
