The logical data model of vector graphics is based on the mathematics of coordinate geometry, in which shapes are defined as a set of points in a two- or three-dimensional cartesian coordinate system, as p = (x, y) or p = (x, y, z).
The related OGR library (OGR Simple Features Library [2]), which is part of the GDAL source tree, provides a similar ability for simple features vector graphics data. GDAL was developed mainly by Frank Warmerdam until the release of version 1.3.2, when maintenance was officially transferred to the GDAL/OGR Project Management Committee under the ...
First a mask is created, which includes one or more vector primitives or forms, i.e., circles, squares, TrueType fonts, Bézier curves, etc. Then source must be defined, which may be a color, a color gradient, a bitmap or some vector graphics, and from the painted parts of this source a die cut is made with the help of the above defined mask.
Architecture of OpenSceneGraph, an open-source 3D graphics API supporting feature-rich and widely adopted scene graph implementation.. A scene graph is a general data structure commonly used by vector-based graphics editing applications and modern computer games, which arranges the logical and often spatial representation of a graphical scene.
The files store vector graphics data, embed or reference external bitmap images, and also a revision history of the project. Synfig can render to video formats such as AVI, Theora and MPEG, as well as animated graphics formats such as MNG and GIF. It can also render to a sequence of numbered image files, using formats such as PNG, BMP, PPM and ...
Vector graphics consists of geometrical primitives.. In vector computer graphics, CAD systems, and geographic information systems, geometric primitive (or prim) is the simplest (i.e. 'atomic' or irreducible) geometric shape that the system can handle (draw, store).
A commercial library for 3D Boolean operations: sgCore C++/C# library. The comp.graphics.algorithms FAQ, solutions to mathematical problems with 2D and 3D Polygons. Matthias Kramm's gfxpoly, a free C library for 2D polygons (BSD license). Klaas Holwerda's Boolean, a C++ library for 2D polygons.
In computer graphics, swizzles are a class of operations that transform vectors by rearranging components. [1] Swizzles can also project from a vector of one dimensionality to a vector of another dimensionality, such as taking a three-dimensional vector and creating a two-dimensional or five-dimensional vector using components from the original vector.
