JBOD (just a bunch of disks or just a bunch of drives) is an architecture using multiple hard drives exposed as individual devices.Hard drives may be treated independently or may be combined into one or more logical volumes using a volume manager like LVM or mdadm, or a device-spanning filesystem like btrfs; such volumes are usually called "spanned" or "linear | SPAN | BIG".
Along with support for simple, spanned and striped volumes, the Windows 2000 Server family also supports fault-tolerant volume types. The types supported are mirrored volumes and RAID-5 volumes: Mirrored volumes: the volume contains several disks, and when data is written to one it is also written to the other disks. This means that if one disk ...
In volumetric lighting, the light cone emitted by a light source is modeled as a transparent object and considered as a container of a "volume". As a result, light has the capability to give the effect of passing through an actual three-dimensional aerosol (e.g. fog, dust, smoke, or steam) that is inside its volume, just like in the real world.
Effective mode volume is proportional to the breadth of the relative distribution of power amongst the modes in a multimode fiber. It is not truly a spatial volume but rather an "optical volume" equal to the product of area and solid angle. The power divided by the effective mode volume is proportional to the radiance of the light emitted by ...
Geometric shapes are precise edged and mathematically consistent curves, [citation needed] they are pure forms and so consist of circles, squares, spirals, triangles, while geometric forms are simple volumes, such as cubes, cylinders, and pyramids. [3] They generally dominate architecture, technology, industry and crystalline structures.
An LED strip, tape, or ribbon light is a flexible circuit board populated by surface-mount light-emitting diodes (SMD LEDs) and other components that usually comes with an adhesive backing. Traditionally, strip lights had been used solely in accent lighting, backlighting, task lighting, and decorative lighting applications, such as cove lighting .
A structured-light 3D scanner is a device that measures the three-dimensional shape of an object by projecting light patterns—such as grids or stripes—onto it and capturing their deformation with cameras. [1]
An approximation to the light entering a region from a wide range of directions, used to avoid needing an exact solution to the rendering equation. Ambient occlusion (AO) Effect approximating, in an inexpensive way, one aspect of global illumination by taking into account how much ambient light is blocked by nearby geometry, adding visual clues ...
