Computer cooling. A finned air cooled heatsink with fan clipped onto a CPU, with a smaller passive heatsink without fan in the background. A 3-fan heatsink mounted on a video card to maximize cooling efficiency of the GPU and surrounding components. Commodore 128DCR computer's switch-mode power supply, with a user-installed 60 mm cooling fan.
Gamma correction is a type of power law function whose exponent is the Greek letter gamma ( γ ). It should not be confused with the mathematical Gamma function. The lower case gamma, γ, is a parameter of the former; the upper case letter, Γ, is the name of (and symbol used for) the latter (as in Γ ( x )).
Thermal management (electronics) 60×60×10 mm straight-finned heat sink with a thermal profile and swirling animated forced convection flow trajectories from a tubeaxial fan, predicted using a CFD analysis package. Free convection thermoelectric cooler (Peltier cooler) with heat sink surface temperature contours, and rising warmer air and ...
Computer graphics lighting. Computer graphics lighting is the collection of techniques used to simulate light in computer graphics scenes. While lighting techniques offer flexibility in the level of detail and functionality available, they also operate at different levels of computational demand and complexity.
The ambient occlusion map (middle image) for this scene darkens only the innermost angles of corners. In 3D computer graphics, modeling, and animation, ambient occlusion is a shading and rendering technique used to calculate how exposed each point in a scene is to ambient lighting. For example, the interior of a tube is typically more occluded ...
Color temperature is conventionally expressed in kelvins, using the symbol K, a unit for absolute temperature. Color temperatures over 5000 K are called "cool colors" (bluish), while lower color temperatures (2700–3000 K) are called "warm colors" (yellowish). "Warm" in this context is with respect to a traditional categorization of colors ...
ASUS GeForce GTX 650 Ti, a PCI Express 3.0 ×16 graphics card, using two fans for cooling. Used to cool the heatsink of the graphics processing unit or the memory on graphics cards. These fans were not necessary on older cards because of their low power dissipation, but most modern graphics cards designed for 3D graphics and gaming need their ...
General-purpose computing on graphics processing units. General-purpose computing on graphics processing units ( GPGPU, or less often GPGP) is the use of a graphics processing unit (GPU), which typically handles computation only for computer graphics, to perform computation in applications traditionally handled by the central processing unit ...
