SVG |
Scalable Vector Graphics |
Describe two-dimensional graphics in XML |
Language for describing two-dimensional graphics in XML. SVG allows for three types of graphic objects: vector graphic shapes (e.g., paths consisting of straight lines and curves), images and text. Graphical objects can be grouped, styled, transformed and composited into previously rendered objects. Text can be in any XML namespace suitable to the application, which enhances searchability and accessibility of the SVG graphics. The feature set includes nested transformations, clipping paths, alpha masks, filter effects, template objects and extensibility. |

VRML |
Virtual Reality Modelling Language |
Standard file format for representing 3-dimensional (3D) interactive vector graphics, designed particularly with the World Wide Web in mind. |
Text file format where for example vertices and edges for a 3D polygon can be specified along with the surface colour, image-mapped textures, shininess, transparency, and so on. URLs can be associated with graphical components so that a web browser might fetch a web-page or a new VRML file from the Internet when the user clicks on the specific graphical component. Animations, sounds, lighting, and other aspects of the virtual world can interact with the user or may be triggered by external events such as timers. |

X3D |
X3D |
ISO standard for real time 3D graphics, successor to Virtual Reality Modelling Language (VRML). |
X3D features extensions to VRML (e.g. Humanoid Animation, Nurbs, GeoVRML etc.), the ability to encode the scene using an XML syntax as well as the Open Inventor-like syntax of VRML97, and enhanced application programmer interfaces (APIs). |

GML |
Geography Mark-up Language. |
XML grammar defined by the Open Geospatial Consortium (OGC) to express geographical features. |
GML serves as a modelling language for geographic systems as well as an open interchange format for geographic transactions on the Internet |
