In 2010, "SuperTuxKart" switched away from using SDL and PLIB libraries (used through version 0.6.2) for graphics and started using the Irrlicht Engine. This change was released in version 0.7. In 2013 and 2014, the game participated in Google Summer of Code as a mentoring organization. The migration of the code repository from Sourceforge to GitHub was officially announced on 17 January 2014, though the assets repository and downloads remain on Sourceforge. On April 21, 2015, version 0.9 was released which used a highly modified version of Irrlicht, including an entirely new graphics renderer dubbed Antarctica. This enabled much better graphics with features such as dynamic lighting, ambient occlusion, depth of field, real-time shadow mapping, and more. In early 2018, Antarctica switched to using PBR in the git version of the game. Antarctica Rendering Engine uses OpenGL 3.3+ (or OpenGL ES on suitable platforms) and GLSL for most of the graphical work.
