| # Fuchsia UI services |
| |
| The Fuchsia tree does not provide a full-fledged end-user UI. Instead, it provides services that provide a foundation upon which to build secure, performant, multi-process UIs. |
| |
| These services include: |
| |
| ## Scenic, the Fuchsia graphics engine |
| |
| Scenic ([doc](scenic.md)) provides a retained-mode scene graph that allows graphical objects from multiple processes to be composed and rendered within a unified lighting environment. |
| |
| ## Input |
| |
| The input subsystem ([doc](input.md)) is responsible for discovering the available input devices, and allowing clients to register for events from these devices. |
