On January 1, 1998, Blender was released publicly online as SGI freeware.

Some design choices and experiences for Blender were carried over from an earlier software application, called Traces, that Roosendaal developed for NeoGeo on the Commodore Amiga platform during the 1987–1991 period. The name Blender was inspired by a song by the Swiss electronic band Yello, from the album Baby, which NeoGeo used in its showreel. Version 1.00 was released in January 1995, with the primary author being company co-owner and software developer Ton Roosendaal. The Dutch animation studio NeoGeo (not related to Neo Geo video game hardware) started to develop Blender as an in-house application, and based on the timestamps for the first source files, Januis considered to be Blender's birthday.

Please ensure that make clean is executed before requesting a pull request How to Port an Operation ¶ Please include the test results (correctness and timing), and name the pull request according to the operation you're working on and the vendor you're optimizing for, eg. After every discussion, if your kernel has the fastest speed for the vendor, you can create a pull request to have your changes merged. It is recommended that you fork this repository and create your branches there. Likewise, we have a slack channel for discussions pertaining to development and issues here, GEGL-OpenCL Slack Contributing ¶ However, there is still a lot of operations that need porting as listed in the Google Sheet below. There already exists OpenCL integration into GEGL and some operations have already been ported to run on OpenCL. The code for GEGL-OpenCL can be found at GEGL-OpenCL Github. Read the document above for more information, or refer to the links below for the respective platformsĮnsure that BABL is installed first before GEGL. A vocabulary to formulate new pixel formats from existing primitives is provided as well as the framework to add new color models and data types.įor a brief explanation on how GEGL works, read this document Index ¶ BABL allows converting between different methods of storing pixels known as pixel formats that have with different bitdepths and other data representations, color models and component permutations. GEGL also depends on BABL to translate pixel formats. GEGL provides such operations for loading and storing images, adjusting colors, filtering in different ways, transforming and compositing images.
With GEGL you chain together image processing operations represented by nodes into a graph. GEGL (Generic Graphics Library) is a graph based image processing framework. GEGL-OpenCL ¶ First official OPP (OpenCL Porting Project) of ¶
