The open source software package [[Chromium (computer graphics)|Chromium]] provides a parallel rendering mechanism for existing applications. It intercepts the [[OpenGL]] calls and processes them, typically to send them to multiple rendering units driving a [[video wall|display wall]].
Equalizer (http://www.equalizergraphics.com) is an open source rendering [[Software framework|framework]] and resource management system for multipipe applications. Equalizer provides an [[Application programming interface|API]] to write parallel, scalable visualization applications which are configured at run-time by a resource server.<ref>http://www.equalizergraphics.com</ref>
[[OpenSG]] (http://www.opensg.org) is an open source [[Scene graph|scenegraph]] system that provides parallel rendering capabilities, especially on clusters. It hides the complexity of parallel [[Thread (computer science)|multi-threaded]] and clustered applications and supports sort-first as well as sort-last rendering.<ref>http://www.opensg.org</ref>
Golem (https://golem.network) is an open source [[Decentralizeddecentralized application|dApp]] used for parallel computing that currently works with rendering in [[Blender_(software)|Blender]] and has plans to incorporate more uses.<ref>https://golem.network</ref>
