X3D is the ISO standard XML-based file format for representing 3D computer graphics, the successor to the Virtual Reality Modeling 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, or binary formatting, and enhanced application programming interfaces (APIs).

X3D extension supports multi-stage and multi-texture render, it also supports shader with lightmap and normalmap. In 2010 X3D supports deferred rendering architecture. Now X3D can import SSAO, CSM and Realtime Environment Reflection/Lighting, but doesn’t need care much about polygon counts. The user can also use optimizations like BSP/QuadTree/OctTree or culling in the X3D scene.

X3D also benefits from other open source standards like XML, DOM and XPath. The user can easily develop content tools like an exporter and editor which make content creation and optimization tasks easy.

X3D defines several profiles (sets of components) for various levels of capability including X3D Core, X3D Interchange, X3D Interactive, X3D CADInterchange, X3D Immersive, and X3D Full. Browser makers can define their own component extensions prior to submitting them for standardisation by the Web3D Consortium. Formal review and approval is then performed by the International Organization for Standardization (ISO).

Garry Kimovich Kasparov (Russian: Га́рри Ки́мович Каспа́ров, Russian pronunciation: [ˈɡarʲɪ ˈkʲiməvʲɪtɕ kɐˈsparəf]; born Garik Kimovich Weinstein, 13 April 1963) is a Russian (formerly Soviet) chess grandmaster, a former World Chess Champion, writer, political activist, considered by many to be the greatest chess player of all time.

Kasparov became the youngest ever undisputed World Chess Champion in 1985 at the age of 22 by defeating then-champion Anatoly Karpov. He held the official FIDE world title until 1993, when a dispute with FIDE led him to set up a rival organization, the Professional Chess Association. He continued to hold the "Classical" World Chess Championship until his defeat by Vladimir Kramnik in 2000. He was the first world champion to lose a match to a computer under standard time controls, when he lost to Deep Blue in 1997.

Kasparov's ratings achievements include being rated world No. 1 according to Elo rating almost continuously from 1986 until his retirement in 2005 and holding the all-time highest rating of 2851. He was the world No. 1 ranked player for 255 months, by far the most of all-time and nearly three times as long as his closest rival, Anatoly Karpov. Kasparov also holds records for consecutive tournament victories and Chess Oscars.
