They are usually flat, without information about the light's direction, whilst some game engines use multiple lightmaps to provide approximate directional information to combine with normal-maps. Lightmaps may also store separate precalculated components of lighting information for semi-dynamic lighting with shaders, such as ambient-occlusion ...
Mesopic levels range approximately from 0.01 to 3.0 cd/m 2 in luminance. Most nighttime outdoor and street lighting conditions are in the mesopic range. [2] Human eyes respond to certain light levels differently. This is because under high light levels typical during daytime (photopic vision), the eye uses cones to process light.

There are two luminous efficiency functions in common use. For everyday light levels, the photopic luminosity function best approximates the response of the human eye. For low light levels, the response of the human eye changes, and the scotopic curve applies. The photopic curve is the CIE standard curve used in the CIE 1931 color space.
A tea light-type candle, imaged with a luminance camera; false colors indicate luminance levels per the bar on the right (cd/m 2). Luminance is a photometric measure of the luminous intensity per unit area of light travelling in a given direction. [1]
F3 is commonly used to activate a search function in applications, often cycling through results on successive presses of the key. ⇧ Shift+ F3 is often used to search backwards. Some applications such as Visual Studio support Control+ F3 as a means of searching for the currently highlighted text elsewhere in a document.
A form of level of detail management has been applied to texture maps for years, under the name of mipmapping, also providing higher rendering quality. It is commonplace to say that "an object has been LOD-ed " when the object is simplified by the underlying LOD-ing algorithm as well as a 3D modeler manually creating LOD models.
Photopic vision is the vision of the eye under well-lit conditions (luminance levels from 10 to 10 8 cd/m 2). In humans and many other animals, photopic vision allows color perception , mediated by cone cells , and a significantly higher visual acuity and temporal resolution than available with scotopic vision .
