Caustic Graphics
Caustic Graphics was a computer graphics and fabless semiconductor company that developed technologies to bring real-time ray-traced computer graphics to the mass market. The company name derived from an optical effect caused by the concentration of light on to a surface resulting from focusing through reflection or refraction phenomena. Caustic was founded on the premise that realistic 3D graphics would be easier to create if GPU hardware were as efficient at processing a ray as processing a vertex or fragment using existing rasterisation methods. History Caustic was founded in 2006 by three ex-Apple engineers, one of which had developed graphics technologies for the 5th Generation iPod and 1st Generation iPhone. The founding business plan was to build a complete real-time ray traced graphics system to initially accelerate professional 3D visualisation and later for entertainment applications on PCs and gaming consoles. In 2008, Caustic Graphics acquired Splutterfish, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Privately Held Company
A privately held company (or simply a private company) is a company whose shares and related rights or obligations are not offered for public subscription or publicly negotiated in the respective listed markets, but rather the company's stock is offered, owned, traded, exchanged privately, or Over-the-counter (finance), over-the-counter. In the case of a closed corporation, there are a relatively small number of shareholders or company members. Related terms are closely-held corporation, unquoted company, and unlisted company. Though less visible than their public company, publicly traded counterparts, private companies have major importance in the world's economy. In 2008, the 441 list of largest private non-governmental companies by revenue, largest private companies in the United States accounted for ($1.8 trillion) in revenues and employed 6.2 million people, according to ''Forbes''. In 2005, using a substantially smaller pool size (22.7%) for comparison, the 339 companies on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PC Game
A personal computer game, also known as a PC game or computer game, is a type of video game played on a personal computer (PC) rather than a video game console or arcade machine. Its defining characteristics include: more diverse and user-determined gaming hardware and software; and generally greater capacity in input, processing, video and audio output. The uncoordinated nature of the PC game market, and now its lack of physical media, make precisely assessing its size difficult. In 2018, the global PC games market was valued at about $27.7 billion. Home computer games became popular following the video game crash of 1983, leading to the era of the "bedroom coder". In the 1990s, PC games lost mass-market traction to console games, before enjoying a resurgence in the mid-2000s through digital distribution on services such as Steam and GOG.com. Newzoo reports that the ''PC gaming sector'' is the third-largest category (and estimated in decline) across all platforms , with the ' ...

Bounding Volume Hierarchy
A bounding volume hierarchy (BVH) is a tree structure on a set of geometric objects. All geometric objects, that form the leaf nodes of the tree, are wrapped in bounding volumes. These nodes are then grouped as small sets and enclosed within larger bounding volumes. These, in turn, are also grouped and enclosed within other larger bounding volumes in a recursive fashion, eventually resulting in a tree structure with a single bounding volume at the top of the tree. Bounding volume hierarchies are used to support several operations on sets of geometric objects efficiently, such as in collision detection and ray tracing. Although wrapping objects in bounding volumes and performing collision tests on them before testing the object geometry itself simplifies the tests and can result in significant performance improvements, the same number of pairwise tests between bounding volumes are still being performed. By arranging the bounding volumes into a bounding volume hierarchy, the time ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Directed Acyclic Graph
In mathematics, particularly graph theory, and computer science, a directed acyclic graph (DAG) is a directed graph with no directed cycles. That is, it consists of vertices and edges (also called ''arcs''), with each edge directed from one vertex to another, such that following those directions will never form a closed loop. A directed graph is a DAG if and only if it can be topologically ordered, by arranging the vertices as a linear ordering that is consistent with all edge directions. DAGs have numerous scientific and computational applications, ranging from biology (evolution, family trees, epidemiology) to information science (citation networks) to computation (scheduling). Directed acyclic graphs are sometimes instead called acyclic directed graphs or acyclic digraphs. Definitions A graph is formed by vertices and by edges connecting pairs of vertices, where the vertices can be any kind of object that is connected in pairs by edges. In the case of a directed graph, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minimum Bounding Box
In geometry, the minimum or smallest bounding or enclosing box for a point set in dimensions is the box with the smallest measure (area, volume, or hypervolume in higher dimensions) within which all the points lie. When other kinds of measure are used, the minimum box is usually called accordingly, e.g., "minimum-perimeter bounding box". The minimum bounding box of a point set is the same as the minimum bounding box of its convex hull, a fact which may be used heuristically to speed up computation. The terms "box" and "hyperrectangle" come from their usage in the Cartesian coordinate system, where they are indeed visualized as a rectangle (two-dimensional case), rectangular parallelepiped (three-dimensional case), etc. In the two-dimensional case it is called the minimum bounding rectangle. Axis-aligned minimum bounding box The axis-aligned minimum bounding box (or AABB) for a given point set is its minimum bounding box subject to the constraint that the edges of the box are ...

Ray-tracing Hardware
Ray-tracing hardware is special-purpose computer hardware designed for accelerating ray tracing calculations. Introduction: Ray tracing and rasterization The problem of rendering 3D graphics can be conceptually presented as finding all intersections between a set of " primitives" (typically triangles or polygons) and a set of "rays" (typically one or more per pixel). Up to 2010, all typical graphic acceleration boards, called graphics processing units (GPUs), used rasterization algorithms. The ray tracing algorithm solves the rendering problem in a different way. In each step, it finds all intersections of a ray with a set of relevant primitives of the scene. Both approaches have their own benefits and drawbacks. Rasterization can be performed using devices based on a stream computing model, one triangle at the time, and access to the complete scene is needed only once. The drawback of rasterization is that non-local effects, required for an accurate simulation of a scene, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apple Insider
The Apple community is a group of people interested in Apple Inc. and its products, who report information in various media. Generally this has evolved into a proliferation of websites, but latterly has also expanded into podcasts (both audio and video), either speculating on rumors about future product releases, simply report Apple-related news stories, or have discussions about Apple's products and how to use them. Such stories and discussions may include topics related to physical products like the Macintosh and iOS devices (e.g., the iPhone, iPod, and iPad); software and operating systems, like Final Cut Pro, Logic Pro X, iWork, iOS, and macOS; or even services Apple offers like iCloud, iTunes Store, or Apple Music. Apple enjoys a cult-like following for its platforms, especially following the massive increase in popularity for the brand brought about by the huge increase in sales for all its products that started around the time the company introduced the original iPod in l ...
