ray tracing
In computer graphics, an advanced technique for adding realism to an image by including variations in shade, color intensity, and shadows that would be produced by having one or more light sources. Ray tracing software works by simulating the path of a single light ray as it would be absorbed or reflected by various objects in the image. To work properly, the artist must specify parameters of the light source (intensity, color, etc.) as well as all the objects (how reflective or absorbent the materials are).
Ray tracing requires enormous computational resources, and is supported by only the most advanced graphics systems.

- read
(v.) To copy data to a place where it can be used by a program. The term is commonly used to describe copying data from a storage medium, such as a disk, to main memory. (n.) The act of reading. For example, a fast disk drive performs 100 reads per second.
- read-only
Capable of being displayed, but not modified or deleted. All operating systems allow you to protect objects (disks, files, directories) with a read-only attribute that prevents other users from modifying the object.
- read/write
(rēd/rīt) (adj.) Capable of being displayed (read) and modified (written to). Most objects (disks, files, directories) are read/write, but operating systems also allow you to protect objects with a read-only attribute that prevents other users from modifying the object.
- readme file
A small text file that comes with many software packages and contains information not included in the official documentation. Typically, readme files contain late-breaking information that could not be included in the printed documentation.
- real mode
An execution mode supported by the Intel 80286 and later processors. In real mode, these processors imitate the Intel 8088 and 8086 microprocessors, although they run much faster. The other mode available is called protected mode. In protected mode, programs can access extended memory and virtual memory. Protected mode also supports multitasking. The 80386 and […]
