Because data within a single tile is stored contiguously in memory, it aligns perfectly with modern CPU cache lines. When the processor fetches data to draw a tile, it implicitly loads adjacent visual data, minimizing costly RAM access delays.
In the Oberon programming language, the implementation of the tiling logic is elegantly sparse. The system defines a generic display manager often anchored around modules like Viewers and Display . Oberon Object Tiler
The tiler organizes objects into a tree structure. A top-level viewer contains tracks, which contain frames, which may contain sub-gadgets. Efficiency and UX Benefits Because data within a single tile is stored
Viewer = RECORD next, prev: Viewer; (* linked list *) frame: Rectangle; (* absolute screen coordinates *) obj: Object; (* typed object to display *) menu: MenuProc; (* right-click menu handler *) handle: HandleProc; (* resize/move handler *) END The system defines a generic display manager often
The Oberon screen was treated as a single, cohesive "display file" or raster. The Object Tiler is the mechanism responsible for breaking this abstract display file into visual pieces and mapping them onto the physical screen.
Allow the tiler to apply incremental changes to objects as they are duplicated across the grid.
In essence, the Oberon Object Tiler answers three questions simultaneously:
