OpenVG is an API designed for hardware-accelerated 2D vector graphics. Its primary platforms are mobile phones, gaming & media consoles and consumer electronic devices. It was designed to help manufacturers create more attractive user interfaces by offloading computationally intensive graphics processing from the CPU onto a GPU to save energy. The OpenGL ES library provides similar functionality for 3D graphics. OpenVG is managed by the 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, Symbian, and Sun Microsystems. Other firms including chip manufacturers 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 implementation of OpenVG built on top of 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, 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.

Adreno GPUs support OpenVG 1.1. Qualcomm provides an SDK for Android.

For GPUs

Mesa Gallium3D – VMware/Tungsten Graphics provides an OpenVG implementations for cards with Gallium drivers (Gallium drivers for nVidia, AMD/ATI, and VMware are available). OpenVG has been removed from Mesa in version 10.6.

For media accelerators

Hanwha Systems AlexVG-forma – Accelerating Vector Graphics API on Media acceleration hardware. Using horse power of Multimedia or 2D bitmap graphics hardware.

On OpenGL, OpenGL ES

Hooked Wireless OpenVG – complete implementation of both OpenVG 1.01 and OpenVG 1.1, implemented on top of OpenGL ES, and is fully conformant. Claim “It leverages proprietary technology from Hooked in the areas of tessellation and triangulation for shapes and curve.” First released in Feb/2008.
Hanwha Systems AlexVG-forge – An OpenVG engine which is 2D vector graphic standard by using the graphic chip that supports OpenGL/OpenGL ES.
Mazatech AmanithVG GLE – commercial. Built on top of OpenGL 1.1+ and OpenGL ES 1.x. Claim “achieving better performance than software rasterizers in terms of high resolution animations and complex special effects (transparencies, fading, realtime rotoscaling and many others).”
MonkVG – open source (BSD), only "OpenVG like"
ShivaVG – open source (LGPL)
ShaderVG – based on ShivaVG but implements draw calls GLSL shaders
