indentation, as in Python and Haskell s-expressions with a syntactic keyword such as prog or let (as in the Lisp family) In 1968 (with ALGOL 68 ), then in Edsger W. Dijkstra 's 1974 Guarded Command Language the conditional and iterative code block are alternatively terminated with the block reserved word reversed : e.g. if ~ then ~ elif ~ else ...
The visual hull of a three-dimensional object, with respect to a set of viewpoints, consists of the points such that every ray from a viewpoint through intersects the object. Equivalently it is the intersection of the (non-convex) cones generated by the outline of the object with respect to each viewpoint.
Many PDF viewers are provided free of charge from a variety of sources. Programs to manipulate and edit PDF files are available, usually for purchase. There are many software options for creating PDFs, including the PDF printing capabilities built into macOS, iOS, [72] and most Linux distributions.
Boxing is the operation of converting a value-type object into a value of a corresponding reference type. [108] Boxing in C# is implicit. Unboxing is the operation of converting a value of a reference type (previously boxed) into a value of a value type. [108] Unboxing in C# requires an explicit type cast. A boxed object of type T can only be ...
Most implementations of the ray casting algorithm consecutively check intersections of a ray with all sides of the polygon in turn. In this case the following problem must be addressed. If the ray passes exactly through a vertex of a polygon, then it will intersect 2 segments at their endpoints. While it is OK for the case of the topmost vertex ...
Irrlicht (pronounced [ˈɪʁlɪçt] in German) is an open-source game engine written in C++.It is cross-platform, officially running on Windows, macOS, Linux and Windows CE and due to its open nature ports to other systems are available, including FreeBSD, Xbox (up to Irrlicht version 1.8.1), PlayStation Portable, [1] Symbian, [2] iPhone, [3] AmigaOS 4, [4] Sailfish OS via a Qt/QML wrapper, [5 ...
A fixed-point representation of a fractional number is essentially an integer that is to be implicitly multiplied by a fixed scaling factor. For example, the value 1.23 can be stored in a variable as the integer value 1230 with implicit scaling factor of 1/1000 (meaning that the last 3 decimal digits are implicitly assumed to be a decimal fraction), and the value 1 230 000 can be represented ...
