Sweep Line Visualiser

This visualisation uses AI Generated code, finetuned for the best visualisation, not code quality

sweepline.mov

Interactive Raylib visualiser for interval-overlap intuition using a sweep line, active-set tracking, and several page variants that show how overlap detection changes as the line moves.

What This Visualisation Shows

• How a sweep line turns interval overlap into ordered event processing
• How the active set changes as starts and ends are crossed
• How different page setups emphasize geometry, event order, and active overlaps
• Why sorting and event discipline matter more than brute-force pair checks
