cogl: cogl (3D graphics API) cogl: cogl: Cogl is a small open source library for using 3D graphics hardware for cogl: rendering. The API departs from the flat state machine style of OpenGL cogl: and is designed to make it easy to write orthogonal components that cogl: can render without stepping on each others toes. cogl: cogl: Having other backends, besides OpenGL, such as drm, Gallium or D3D are cogl: options we are interested in for the future. cogl: cogl: https://www.gnome.org/
