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, 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 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. On 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.
Implementations
In hardware
Renesas SuperH SH2A based SH7269 solution. Developed for low system-cost embedded GUIs, with up to 2.5MB of embedded SRAM for picture-buffer.
AMD/ATI Z160 and Z180 OpenVG 1.x Graphics core. Implemented in the Freescale i.MX35, i.MX51 and i.MX53. IP sold to Qualcomm and rebranded "Adreno" for Snapdragon cores.
Vivante GC400 and above are 3D graphics cores supporting OpenGL ES 2.0 and OpenVG 1.1
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. OpenVG has been removed from Mesa in version 10.6.
For media accelerators
HuOne 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.
HuOne 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.”
MonkVG – open source, only "OpenVG like"
ShivaVG – open source
In software
Khronos OpenVG Reference implementation
HuOne AlexVG – First released in Sep/2005
Mazatech AmanithVG – OpenVG crossplatform library with pure software and OpenGL rendering backends
