Use generic terms (geometry, mesh, camera, viewport) rather than application-specific terminology (map, terrain, navigation) + +### Library Interface Boundaries +QuickViz is designed as a toolkit of building blocks for robotics visualization applications. The interface design clearly distinguishes between different levels of user interaction: + +**Direct Use Components** (Ready-to-use, minimal configuration): +- Core rendering primitives (points, lines, meshes, textures) +- Standard UI widgets (buttons, sliders, text inputs) +- Camera controllers and viewport management +- File I/O utilities (image, mesh formats) + +**Configurable Components** (Parameters and settings exposed): +- Rendering passes and shaders (lighting models, post-processing) +- Layout managers and containers +- Event handling and input mapping +- Color schemes and visual styling + +**Extensible Components** (Virtual interfaces for inheritance): +- `Renderable`, `InputHandler`, `SceneObject` interfaces +- Custom drawing and interaction tools +- Specialized data visualization widgets +- Custom file format adapters + +**Build-Upon Components** (Library hooks apps compose into bigger frameworks): +- Scene composition (`SceneManager` + `OpenGlObject` registration) +- Tool registration (`InteractionTool` interface + `ToolManager`) +- Threading and job hand-off boundaries +- Custom data adapters (e.g., `pcl_bridge` pattern) + +> Editor-shaped frameworks — command/undo stacks, scene graphs with parent/child +> hierarchies, project-file persistence, history panels — are **not** part of the +> library. They live in consuming apps (see `sample/editor/` for a reference +> implementation) and are built on top of the hooks above. + +> **Design Rule**: Generic robotics and graphics terminology should be preferred over domain-specific names. For example, use "Mesh", "PointCloud", "Camera" rather than "Map", "Scan", "Observer". This ensures the library remains broadly applicable across different robotics applications. + +### When to Create or Split Modules +Create (or split) a module when: +- **Two or more** other modules depend on a concept +- The code has **distinct lifecycles** (e.g., GPU resources vs. CPU parsing) +- You need to **swap implementations** behind an interface +- You want **separate testability** (unit tests without GL context) + +**Do not** create a module if it only wraps 1-2 functions without clear benefit. + +## Architecture & Dependencies + +### Module Structure +``` +src/ +├── core/ # Event system, buffers, utilities (depends on nothing) +├── imview/ # GLFW window management, ImGui integration +├── widget/ # Cairo drawing, image widgets, plotting +├── gldraw/ # OpenGL 3D rendering, point clouds, textures +├── pcl_bridge/ # Optional PCL adapter (file loading, conversions) +├── cvdraw/ # OpenCV-based drawing utilities (optional bridge) +└── third_party/ # imgui, implot, stb, yoga, googletest + +sample/ # Reference applications built ON TOP of the library +``` + +### Dependency Rules +- **Core** (math, logging, utilities) depends on nothing else +- **Model** (scene/data types, transforms, selection) may depend on Core +- **Graphics** (GL wrappers, passes, shaders) may depend on Core and Model +- **Tools/Interaction** (picking, gizmos, measure) may depend on Graphics + Model +- **UI** (ImGui panels, docking) can depend on everything but is never depended on +- **Bridges/Adapters** (OpenCV/PCL/etc.) depend outward; nothing core depends on them + +> **Rule**: Lower layers never include headers from higher layers + +### Library Boundary: `src/` is visualization-only +QuickViz is a visualization library.

new unified EventDispatcher implementation. + +## ⚠️ **BREAKING CHANGES NOTICE** ⚠️ + +**Legacy compatibility has been completely removed.** All existing code using the old EventDispatcher APIs will need to be updated to use the modern interface. + +## Overview + +The EventDispatcher has been completely redesigned with modern C++ features and a clean API. The old legacy compatibility layer has been removed to ensure a maintainable, high-performance codebase. + +## Key Improvements + +### New Features +- **Priority-based handler ordering**: Handlers are processed by priority (higher values first) +- **Event consumption mechanism**: Handlers can consume events to stop further propagation +- **Thread-safe operations**: All operations are protected by mutex +- **Type-safe event handling**: Template-based handlers for specific event types +- **Clean modern API**: Function-based handlers with lambda support +- **Enable/disable support**: Per-handler and global enable/disable functionality + +### Architectural Changes +- **Header-only implementation**: No separate .cpp file needed +- **Modern InputDispatcher**: Clean interface specialized for InputEvents +- **No legacy compatibility**: All code must be updated to the new API + +## Breaking Changes + +### 1.
