Changelog v3.0

+

A comprehensive overview of architectural overhauls, performance optimizations, and new features introduced in the latest release.

+
+ +
+ +
+

+ + Major Changes +

+ +
+ +
+

Hybrid Sync & Playback Engine

+

The synchronization architecture between video and radar data was completely rewritten to eliminate stutter and ensure 100% solid logic.

+
    +
  • Moved updateFrame directly into the videoframecallback for display refresh rate synchronization.
    • +
  • Implemented a "Resync Drift Cascade Lockdown" (circuit breaker) to prevent infinite loop freezes on low-end hardware or when multiple tabs are open.
    • +
  • Added frame-rate independent smoothing for UI and sketches.
    • +
  • Centralized timeline slider, manual offset, and play/stop/pause logic into a dedicated sync.js module.
    • +
+
+ +
+

Modular File Loading & Offline Support

+

Monolithic application files were broken down, and the software was adapted to work entirely offline.

+
    +
  • Extracted file handling into src/fileLoader.js, supporting incremental loading (replacing individual files without breaking app state).
    • +
  • Resolved IndexedDB race conditions and startup crashes by ensuring metadata is extracted before parsing visualization data.
    • +
  • Removed Google Fonts dependency and implemented robust fallback logic for local JS libraries, enabling full offline capability.
    • +
  • Corrected caching key usage to ensure auto-reloading from IndexedDB works seamlessly.
    • +
+
+ +
+

Performance & Memory Optimizations

+

Significant improvements to the rendering pipeline to reduce memory allocation and boost framerates.

+
    +
  • Resolved major heap memory issues by iterating through data and drawing rectangles directly to the canvas, changing ctx.fillStyle only once per column.
    • +
  • Improved FPS counter stability with a warmup period to prevent erroneous spikes during new file loads.
    • +
  • Removed unnecessary animation loop calls (e.g., drawing axes every frame) and reduced text content updates for a 20%+ performance boost.
    • +
  • Throttled the MATLAB-style Data Explorer updates to prevent unnecessary function calls when closed.
    • +
+
+ +
+

Living Documentation & Analytical Tools

+

Introduced powerful new ways to explore both the application data and the codebase itself.

+
    +
  • Living Documentation: Added an interactive codebase overview with a visual 3D-styled navigation map and PrismJS syntax highlighting.
    • +
  • Data Explorer: Added a draggable, resizable MATLAB-style data explorer with timeline sync and track information (launched via 'i' key).
    • +
  • Speed Graph: Implemented drag-to-seek, click-to-seek, and hover tooltips for CAN/Ego speeds.
    • +
  • Added an Inter-Frame Timing (IFT) graph with dynamic scaling animations.
    • +
+
+ +
+
+ +
+

+ + Minor Changes & UX Polish +

+ +
+
+ +
+

User Interface

+
    +
  • Added vertical range slider (20m-200m) to adjust RADAR_Y_MAX dynamically.
    • +
  • Double-click reset functionality added to range sliders.
    • +
  • Implemented an auto-loading Quick Start Guide modal on the first session launch.
    • +
  • Refined radar-info-overlay to match plot width and center text.
    • +
  • Added theme-aware color logic for raw point clouds in dark mode.
    • +
  • Removed redundant 'scale' and 'absolute time' metrics from persistent overlays.
    • +
+
+ +
+

Zoom & God Mode

+
    +
  • Implemented smooth mouse tracking for the zoom tooltip.
    • +
  • Added Inverse Zoom Logic.
    • +
  • Constrained God Mode tooltips to remain inside the bounding sketch box.
    • +
  • Fixed hover detection bugs during scroll-zoom interactions.
    • +
  • Switched to relative distance squares to reduce computational overhead and initial hover jitter.
    • +
+
+ +
+

Visuals & Inputs

+
    +
  • Added vehicle dimensions visualization and enhanced track risk coloring.
    • +
  • Added state identifiers directly beside TTC markers.
    • +
  • Fixed visibility toggle for "Confirmed ONLY" tracks.
    • +
  • New keyboard shortcuts: Arrow keys (navigation), Shift key (God Mode activation).
    • +
  • Isolated keyboard shortcut logic to prevent input conflicts.
    • +
  • Video player mute defaults removed; standard controls option added.

Version 3 – Comprehensive Changelog

+

Release Scope: Major architectural overhaul, performance optimization, synchronization stability, enhanced visualization intelligence, and UX refinement.

+ + +

1. Sync Engine Rearchitecture (Major)

+
+

The playback and synchronization system was completely redesigned to eliminate drift, stutter, and race conditions.

+ +

Key Enhancements:

+
    +
  • Migration of update logic to videoFrameCallback for deterministic frame synchronization.
    • +
  • Hybrid video-radar synchronization architecture.
    • +
  • Centralized offset handling logic.
    • +
  • Drift cascade lockdown mechanism.
    • +
  • Manual offset persistence and improved workflow.
    • +
+ +

Impact: Playback engine is now deterministic, stable under low-end hardware, and resilient against multi-tab load conditions.

+
+ + +

2. File Loading & Caching Overhaul (Major)

+
+

Complete modularization of file loading pipeline.

+ +

Improvements:

+
    +
  • Extraction of file handling into fileLoader.js.
    • +
  • Incremental JSON & video loading.
    • +
  • Race condition fixes using Promise-based DB initialization.
    • +
  • Non-blocking IndexedDB caching (fire-and-forget).
    • +
  • fromCache optimization flag.
    • +
  • Unit tests added for loading pipeline.
    • +
+ +

Impact: Eliminated startup crashes, resolved NaN timestamp errors, improved reload time, and increased system robustness.

+
+ + +

3. Performance Optimization Initiative (Major)

+
+

Large-scale performance refactoring across rendering and DOM layers.

+ +

Optimizations:

+
    +
  • Removed unnecessary DOM updates and innerHTML usage.
    • +
  • Canvas rendering optimized to avoid heap allocations.
    • +
  • Reduced redundant draw calls (axes, explorer updates).
    • +
  • 20% performance gain via throttling.
    • +
  • FPS counter stabilization with warmup logic.
    • +
+ +

Impact: Significant memory stability improvement and smoother animation loops.

+
+ + +

4. Advanced Visualization & UX Enhancements (Major)

+
+

Visualization layer significantly upgraded.

+ +

Enhancements:

+
    +
  • Interactive seeking & scrubbing in speed graph.
    • +
  • Smart labeling with density-based speed coloring.
    • +
  • Vehicle dimension visualization.
    • +
  • Risk & state indicators integrated into track markers.
    • +
  • Dynamic vertical range slider (20m–200m).
    • +
  • ROI auto-scaling with dynamic plot boundaries.
    • +
  • Frame-rate independent smoothing for UI interactions.
    • +
+ +

Impact: Visualization now supports intelligent data interpretation and professional-grade interaction behavior.

+
+ + +

5. Zoom & God Mode Enhancements (Major)

+
+
    +
  • Advanced zoom control architecture.
    • +
  • Inverse zoom logic implementation.
    • +
  • Smooth mouse tracking for tooltip precision.
    • +
  • Tooltip bounding constraints.
    • +
  • Shift-key God Mode activation.
    • +
  • Hover jitter reduction via relative distance square optimization.
    • +
+ +

Impact: Enhanced inspection capability for dense radar scenes with stable UX behavior.

+
+ + +

6. In-App Documentation & Architectural Map (Major)

+
+
    +
  • Interactive codebase overview with 3D-styled navigation.
    • +
  • Living documentation integration.
    • +
  • Color-coded architecture explorer (Core, Sync, UI).
    • +
  • PrismJS integration for syntax highlighting.
    • +
  • Mini-map docking navigation system.
    • +
+ +

Impact: Application now self-documents architecture, accelerating onboarding and internal knowledge transfer.

+
+ + +

7. User Guide & Modal System (Major)

+
+
    +
  • First-run detection with sessionStorage.
    • +
  • Auto-launch user guide modal.
    • +
  • Shortcut reference modal.
    • +
  • Standalone shortcuts.html reference page.
    • +
  • Header navigation refactor.
    • +
+
+ + +

8. Data Explorer Enhancements (Major)

+
+
    +
  • Draggable and resizable explorer.
    • +
  • Timeline synchronization.
    • +
  • Additional track metadata display.
    • +
  • Performance throttling.
    • +
+
+ + +

9. Stability & Bug Fixes (Minor)

+
+
    +
  • Fixed smoothing and mapping edge cases.
    • +
  • Corrected hover detection bug during scroll-zoom.
    • +
  • Division-by-zero prevention safeguards.
    • +
  • Fixed handleCloseUpDisplay mouseY bug.
    • +

  • Removed Google Fonts dependency for offline support.
    • +
  • Theme-aware coloring improvements.
    • +
  • Various HTML & margin refinements.
