Short for volume pixel, the smallest distinguishable box-shaped part of a three-dimensional image.
Voxelization is the process of adding depth to an image using a set of cross-sectional images known as a volumetric dataset. These cross-sectional images (or slices) are made up of pixels. The space between any two pixels in one slice is referred to as interpixel distance, which represents a real-world distance. And, the distance between any two slices is referred to as interslice distance, which represents a real-world depth.
The dataset is processed when slices are stacked in computer memory based on interpixel and interslice distances to accurately reflect the real-world sampled volume.
Next, additional slices are created and inserted between the dataset’s actual slices so that the entire volume is represented as one solid block of data.
Now that the dataset exists as a solid block of data, the pixels in each slice have taken on volume and are now voxels.
For a true 3D image, voxels must undergo opacity transformation. Opacity transformation gives voxels different opacity values. This is important when it is crucial to expose interior details of an image that would otherwise be hidden by darker more opaque outside-layer voxels.
Voxel images are primarily used in the field of medicine and are applied to X-Rays, CAT (Computed Axial Tomography) Scans, and MRIs (Magnetic Resonance Imaging) so professionals can obtain accurate 3D models of the human body.
Voxel imaging is also being used to create computer games, so 3D acceleration is not necessary.
Introduced by DEC in August 1978, Video Terminal 100 was the first terminal to use a general-purpose processor for interpreting the newly published (1977) ANSI control codes (ANSI X3.64). Quickly, the vt100 become popular, and the ANSI control codes embodied in the vt100 became a de facto standard. Eventually, IBM adopted them for its line […]
- Vulnerability Scanning
The automated process of proactively identifying security vulnerabilities of computing systems in a network in order to determine if and where a system can be exploited and/or threatened. While public servers are important for communication and data transfer over the Internet, they open the door to potential security breaches by threat agents, such as malicious […]
Acronym for World Wide Web.
Short for World Wide Web Consortium, an international consortium of companies involved with the Internet and the Web. The W3C was founded in 1994 by Tim Berners-Lee, the original architect of the World Wide Web. The organization’s purpose is to develop open standards so that the Web evolves in a single direction rather than being […]
Pronounced way. Short for the Web Accessibility Initiative, an initiative of the World Wide Web Consortium launched in 1997 to ensure that as the Internet grows in usage Web sites are designed to accommodate people with disabilities. Web design can present barriers to people with disabilities, especially people with sensory or neurological disabilities. The WAI […]
