ARAS Visualizer: Version 3

Redesigned to eliminate drift, stutter, and race conditions.

• • Migration to videoFrameCallback for deterministic sync.
• • Hybrid video-radar synchronization architecture.
• • Centralized offset handling logic and persistence.
• • Drift Cascade Lockdown: Prevents seek-loops on low-end hardware.

Complete modularization of the file processing pipeline.

• • Extraction of file handling into dedicated fileLoader.js.
• • Incremental JSON & video loading support.
• • Promise-based IndexedDB initialization (Race condition fixes).
• • Non-blocking "fire-and-forget" caching logic.

Rendering refactored for memory stability and frame-rate consistency.

• • Removed layout-thrashing innerHTML calls in draw loops.
• • Canvas optimization to avoid heap allocations and GC pressure.
• • 20% total performance gain via smart throttling and debouncing.
• • FPS counter stabilization with warmup and smoothing logic.

Intelligent data interpretation and professional UI interactions.

• • Smart Labeling: Greedy collision resolution for track markers.
• • Spectral Density: 95th-percentile normalized speed graph coloring.
• • Vehicle Dimensions: Real-world 2D bounding box visualization.
• • Dynamic range slider (20m–200m) with auto-scaling ROI.

• • Tracking: Exponential mouse smoothing (60Hz/144Hz agnostic).
• • Inverse zoom logic and boundary-aware tooltip constraints.
• • Shift-Key seeking: Integrated timeline scrubbing within radar canvas.
• • Relative distance square optimization to eliminate hover jitter.

• • Interactive Codebase Overview: Integrated 3D-styled navigation.
• • Color-coded architecture explorer (Core, Sync, UI, P5).
• • Local PrismJS integration for high-perf syntax highlighting.
• • Mini-map docking navigation system for architectural modules.

• • First-run detection with automated User Guide onboarding.
• • Standalone Keyboard Shortcut reference modal.
• • Refactored header navigation with theme-aware icons.
• • Internet-free operation (Removed Google Fonts dependency).

• • Draggable and resizable side-panel for granular inspection.
• • Bi-directional timeline synchronization.
• • Expanded metadata for tracked objects (Risk, State, Sign).
• • Throttled data updates to maintain rendering performance.
