+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Overview
+
+This is a Python-based 3D engine editor built with Panda3D and PyQt5. It integrates a comprehensive render pipeline (RenderPipelineFile) and provides VR support through ALVR streaming. The application follows a modular architecture with separate systems for world management, GUI, VR, scripting, and project management.
+
+## Development Commands
+
+This project is a Python application without npm/package.json build commands. Key development commands:
+
+```bash
+# Run the main application
+python3 main.py
+
+# Run specific demo/test files
+python3 demo/basic_gui_demo.py
+python3 demo/script_system_demo.py
+python3 vr_test.py
+
+# Install dependencies
+pip install -r requirements/requirements.txt
+```
+
+## Core Architecture
+
+### Main Application Structure
+- **main.py**: Entry point - initializes MyWorld class which extends CoreWorld
+- **MyWorld class**: Central coordinator that initializes all major systems:
+  - SelectionSystem, EventHandler, ToolManager, ScriptManager
+  - GUIManager, SceneManager, ProjectManager, PropertyPanelManager
+  - InterfaceManager, VRManager, VRInputHandler, ALVRStreamer
+
+### Key Modules
+
+1. **core/**: Core engine functionality
+   - `world.py`: CoreWorld base class extending Panda3DWorld
+   - `selection.py`: Object selection and transformation system
+   - `event_handler.py`: Event processing and input handling
+   - `tool_manager.py`: Tool system management
+   - `script_system.py`: Dynamic script loading and execution
+   - `vr_manager.py`, `vr_input_handler.py`, `alvr_streamer.py`: VR support
+
+2. **ui/**: User interface components
+   - `main_window.py`: MainWindow class using PyQt5
+   - `widgets.py`: Custom PyQt5/Panda3D integration widgets
+   - `property_panel.py`: Object property editing interface
+   - `interface_manager.py`: UI state management
+
+3. **QPanda3D/**: Custom Panda3D-Qt integration
+   - `QPanda3DWidget.py`: Core Qt widget for embedding Panda3D
+   - `Panda3DWorld.py`: Base world class
+   - Translation modules for Qt/Panda3D event mapping
+
+4. **RenderPipelineFile/**: Advanced rendering pipeline
+   - Complete PBR rendering system with plugins
+   - Shader management, lighting, post-processing effects
+   - Material system and environment probes
+
+5. **scripts/**: User scripts directory
+   - Contains example scripts like BouncerScript.py, RotatorScript.py
+   - Scripts are dynamically loaded by the script system
+
+### VR Integration
+- ALVR streaming support for wireless VR
+- VR input handling with hand tracking
+- VR-specific UI and interaction systems
+
+### Demo and Testing
+- **demo/**: Extensive collection of test files and examples
+  - GUI testing examples (basic_gui_demo.py, etc.)
+  - VR testing and integration demos
+  - Picking and selection system tests
+  - Script system demonstrations
+
+## Key Dependencies
+- **Panda3D 1.10.15**: Core 3D engine
+- **PyQt5**: GUI framework
+- **QPanda3D 0.2.10**: Qt-Panda3D integration library
+- Various supporting libraries for VR, rendering, and utilities
+
+## Development Notes
+
+### Camera Controls
+- Default camera speed: 20.0 units
+- Default rotation speed: 10.0 degrees
+- Mouse right-click for camera rotation
+
+### Coordinate System
+The engine uses Panda3D's coordinate system with specific camera and world setups defined in CoreWorld.
+
+### Script System
+Scripts in the `scripts/` directory are automatically discovered and can be loaded dynamically. The script system supports hot-reloading and provides a management interface.
+
+### Render Pipeline Integration
+The project integrates a sophisticated render pipeline with:
+- PBR materials and lighting
+- Post-processing effects (bloom, SSAO, motion blur, FXAA, etc.)
+- Environment mapping and IBL
+- Shadow mapping (PSSM)
+- Day/night cycle simulation
