'''OpenVG''' is an [[application programming interface|API]] designed for [[Hardware acceleration|hardware-accelerated]] [[2D computer graphics|2D]] [[vector graphics]]. Its primary [[computing platform|platforms]] are mobile phones, gaming & media consoles and consumer electronic devices. It was designed to help manufacturers create more attractive [[user interface]]s by offloading computationally intensive graphics processing from the [[central processing unit|CPU]] onto a [[GPU]] to save energy. The OpenGL ES library provides similar functionality for 3D graphics. OpenVG is managed by the [[Non-profit organization|non-profit]] technology [[consortium]] [[Khronos Group]].

== History ==
The OpenVG group was formed on July 6, 2004 by a selection of major firms including [[3Dlabs]], [[Bitboys]], [[Ericsson]], [[Hybrid Graphics]], [[Imagination Technologies]], [[Motorola]], [[Nokia]], [[PalmSource, Inc.|PalmSource]], [[Symbian]], and [[Sun Microsystems]]. Other firms including chip manufacturers [[ATI Technologies|ATI]], [[LG Electronics]], [[Mitsubishi Electric]], [[NVIDIA]], and [[Texas Instruments]] and software- and/or IP vendors DMP, [[Esmertec]], ETRI, [[Falanx Microsystems]], Futuremark, HI Corporation, [[Ikivo]], HUONE (formerly MTIS), Superscape, and Wow4M have also participated in the working group. The first draft specification from the group was made available at the end of 2004, and the 1.0 version of the specification was released on August 1, 2005.

On January 16, 2007, Zack Rusin from Tungsten Graphics announced the start of an independent [[open-source software|open-source]] implementation of OpenVG built on top of [[Qt (toolkit)#Modules|QtOpenGL]].

Shortly after, Ivan Leben started [[ShivaVG]], another open-source project to implement an ANSI C implementation of the specification on top of [[OpenGL]].

Since February 27, 2007 the OpenVG Sample Reference Implementation is available from the Khronos Website under MIT open source license.

On December 9, 2008, the Khronos Group publicly released the OpenVG 1.1 Specification.  This latest revision includes glyph rendering for accelerated text, improved anti-aliasing, and Flash support.  An updated reference implementation is also provided, as well as a conformance test suite.

On May 1, 2009 Rusin added OpenVG state tracker to [[Mesa (computer graphics)|Mesa]], which enables SVG vector graphics to be hardware accelerated by any [[Gallium3D]]-based driver. It was removed again in Mesa 10.6 on June 15, 2015.

In September 2011 OpenVG working group decided not to make any regular meeting for further standardization. However, working group decided to continue maintenance and promotion of OpenVG 1.1 specification.
