+
+## 🔧 具体修复内容
+
+### 1. 中文字体加载系统
+
+在每个文件中添加了统一的字体加载函数：
+
+```python
+def loadChineseFont(self):
+    """尝试加载中文字体"""
+    import os
+    font_paths = [
+        '/usr/share/fonts/truetype/wqy/wqy-microhei.ttc',
+        '/usr/share/fonts/truetype/wqy/wqy-zenhei.ttc',
+        '/usr/share/fonts/truetype/arphic/ukai.ttc',
+        '/usr/share/fonts/truetype/arphic/uming.ttc',
+    ]
+    
+    for font_path in font_paths:
+        if os.path.exists(font_path):
+            try:
+                font = self.loader.loadFont(font_path)
+                if font:
+                    return font
+            except:
+                continue
+    return None
+```
+
+### 2. GUI组件字体设置
+
+#### OnscreenText 组件
+```python
+# ✅ 正确的方法
+text = OnscreenText(
+    text="中文文本",
+    font=self.chinese_font if self.chinese_font else None
+)
+```
+
+#### DirectButton 组件
+```python
+# ✅ 正确的方法（注意使用text_font参数）
+button = DirectButton(
+    text="按钮文本",
+    text_font=self.chinese_font if self.chinese_font else None
+)
+```
+
+#### DirectLabel 组件
+```python
+# ✅ 正确的方法
+label = DirectLabel(
+    text="标签文本",
+    text_font=self.chinese_font if self.chinese_font else None
+)
+```
+
+#### DirectCheckButton 组件
+```python
+# ✅ 正确的方法
+checkbox = DirectCheckButton(
+    text="复选框文本",
+    text_font=self.chinese_font if self.chinese_font else None
+)
+```
+
+#### DirectRadioButton 组件
+```python
+# ✅ 正确的方法
+radio = DirectRadioButton(
+    text="单选按钮文本",
+    text_font=self.chinese_font if self.chinese_font else None
+)
+```
+
+#### DirectOptionMenu 组件
+```python
+# ✅ 正确的方法
+menu = DirectOptionMenu(
+    text="选项菜单",
+    text_font=self.chinese_font if self.chinese_font else None
+)
+```
+
+### 3. 3D空间文本组件
+
+#### TextNode（3D文本）
+```python
+# ✅ 正确的方法
+text3d = TextNode('text-name')
+text3d.setText("3D中文文本")
+if self.chinese_font:
+    text3d.setFont(self.chinese_font)
+```
+
+### 4. 特殊修复
+
+#### DirectRadioButton 回调函数修复
+
+**问题：** `gui_test.py`中DirectRadioButton的回调函数参数不匹配
+
+**修复前：**
+```python
+def onRadioButtonSelect(self, status):  # ❌ 缺少参数
+```
+
+**修复后：**
+```python
+# 添加extraArgs参数
+radio = DirectRadioButton(
+    command=self.onRadioButtonSelect,
+    extraArgs=[i],  # 传递索引参数
+)
+
+# 修改回调函数
+def onRadioButtonSelect(self, index, status):  # ✅ 正确的参数
+```
+
+## 🎨 字体组件对应表
+
+| GUI组件类型 | 字体参数名 | 示例 |
+|-------------|------------|------|
+| OnscreenText | `font` | `OnscreenText(font=chinese_font)` |
+| DirectButton | `text_font` | `DirectButton(text_font=chinese_font)` |
+| DirectLabel | `text_font` | `DirectLabel(text_font=chinese_font)` |
+| DirectCheckButton | `text_font` | `DirectCheckButton(text_font=chinese_font)` |
+| DirectRadioButton | `text_font` | `DirectRadioButton(text_font=chinese_font)` |
+| DirectOptionMenu | `text_font` | `DirectOptionMenu(text_font=chinese_font)` |
+| TextNode | `setFont()` | `textnode.setFont(chinese_font)` |

+# 完整的GUI修复总结报告
+
+## 问题诊断
+
+### 用户报告的问题
+在 `test.py` 程序中，3D文本和虚拟屏幕能正常显示，但其他的GUI组件（按钮、标签、输入框）看不见。
+
+### 根本原因分析
+通过深入分析发现，问题的根本原因是**坐标系统不匹配**：
+
+1. **3D GUI组件**（3D文本、虚拟屏幕）使用**世界坐标系统**
+   - 坐标范围：任意实数范围
+   - 挂载到：`render` 节点下
+   - 位置：世界3D空间中的绝对位置
+
+2. **2D GUI组件**（按钮、标签、输入框）使用**屏幕坐标系统**
+   - 坐标范围：-1 到 1 的标准化坐标
+   - 挂载到：`render2d/aspect2d` 节点下  
+   - 位置：屏幕空间中的相对位置
+
+### 具体问题
+当传入 `(5, 0, 0)` 这样的坐标时：
+- 3D组件正常显示（世界坐标系可以接受任意值）
+- 2D组件超出屏幕范围而不可见（屏幕坐标系只接受-1到1的值）
+
+## 解决方案实施
+
+### 1. 修改GUI创建方法
+在 `test.py` 中修改了三个2D GUI创建方法，添加坐标转换：
+
+```python
+def createGUIButton(self, pos=(0, 0, 0), text="按钮", size=0.1):
+    # 将3D逻辑坐标转换为2D屏幕坐标
+    gui_pos = (pos[0] * 0.1, 0, pos[2] * 0.1)
+    # ... 其余代码保持不变
+```
+
+**转换公式**：屏幕坐标 = 逻辑坐标 × 0.1
+
+### 2. 优化属性面板
+修改了 `updateGUIPropertyPanel()` 方法，为2D GUI组件提供专门的编辑界面：
+
+```python
+def updateGUIPropertyPanel(self, gui_element):
+    gui_type = gui_element.getTag("gui_type")
+    
+    if gui_type in ["button", "label", "entry"]:
+        # 2D GUI使用逻辑坐标编辑（用户友好）
+        logical_x = pos.getX() / 0.1  # 反向转换
+        logical_z = pos.getZ() / 0.1
+        # 显示实际屏幕坐标（只读）
+    else:
+        # 3D GUI继续使用世界坐标编辑
+```
+
+### 3. 添加专用编辑方法
+新增了 `editGUI2DPosition()` 方法处理2D GUI位置编辑：
+
+```python
+def editGUI2DPosition(self, gui_element, axis, value):
+    if axis == "x":
+        new_screen_x = value * 0.1  # 逻辑坐标转屏幕坐标
+        gui_element.setPos(new_screen_x, current_pos.getY(), current_pos.getZ())
+```
+
+## 测试验证
+
+### 创建的测试脚本
+
+1. **test_2d_gui_fix.py** - ShowBase环境基础测试
+   - ✅ 运行成功，所有GUI组件可见可交互
+   - 验证了修复逻辑的正确性
+
+2. **test_gui_complete.py** - Qt集成环境完整测试
+   - ✅ GUI元素创建成功
+   - ⚠️ 在Qt环境中可能存在渲染显示问题
+
+3. **test_simple_gui.py** - 简化验证测试
+   - ✅ 验证了修复逻辑正确
+
+4. **test_qt_fix.py** - Qt环境专门测试
+   - ✅ GUI元素正确创建并添加到scene graph
+   - ⚠️ Qt环境显示可能有问题
+
+5. **test_qt_debug.py** - Qt深度诊断
+   - 🔍 发现Qt环境创建的是`GraphicsBuffer`而不是`GraphicsWindow`
+   - 🔍 这是导致渲染问题的根本原因
+
+6. **test_qt_showbase.py** - ShowBase独立验证
+   - ✅ 在独立窗口中完全正常显示
+
+## 测试结果总结
+
+### ShowBase环境 ✅
+- **状态**：完全成功
+- **表现**：所有2D GUI组件正常显示和交互
+- **验证**：修复方案完全有效
+
+### Qt集成环境 ⚠️
+- **状态**：GUI元素创建成功，但渲染可能有问题
+- **原因**：Qt环境中Panda3D创建的是Buffer而不是Window
+- **影响**：可能需要额外的Qt-Panda3D集成调试
+
+## 技术细节
+
+### 坐标转换系统
+- **逻辑坐标范围**：-50 到 50（用户友好）
+- **屏幕坐标范围**：-1 到 1（Panda3D标准）
+- **转换比例**：0.1（可调整）
+
+### 用户界面改进
+- 2D GUI组件编辑使用逻辑坐标（直观）
+- 显示实际屏幕坐标（调试用）
+- 3D GUI组件继续使用世界坐标
+- 添加了坐标类型提示
+
+### 场景图结构
+```
+render2d/
+├── aspect2d/
+│   ├── DirectButton (2D GUI按钮)
+│   ├── DirectLabel (2D GUI标签)
+│   └── DirectEntry (2D GUI输入框)
+└── camera2d
+
+render/
+├── 3d-text-* (3D文本)
+├── virtual-screen-* (虚拟屏幕)
+└── camera
+```
+
+## 使用建议
+
+### 1. 在主程序中使用
+修复已应用到主程序 `test.py`，所有2D GUI组件现在应该正常显示。
+
+### 2. 创建GUI时的坐标建议
+```python
+# 2D GUI组件 - 使用逻辑坐标（-50到50范围）
+world.createGUIButton((0, 0, 0), "中心按钮")      # 屏幕中心
+world.createGUIButton((-20, 0, 0), "左侧按钮")     # 屏幕左侧
+world.createGUIButton((20, 0, 0), "右侧按钮")      # 屏幕右侧
+
+# 3D GUI组件 - 使用世界坐标
+world.createGUI3DText((0, 5, 2), "3D文本")        # 世界空间位置
+world.createGUIVirtualScreen((3, 8, 0), "屏幕")   # 世界空间位置
+```
+
+### 3. 属性面板编辑
+- 2D GUI：编辑逻辑坐标（-50到50），系统自动转换
+- 3D GUI：直接编辑世界坐标
+- 实际屏幕坐标以只读方式显示
+
+## 后续建议
+
+### 1. Qt集成优化
+如果需要在Qt环境中获得完美的渲染效果，可能需要：
+- 深入研究Qt-Panda3D集成机制
+- 考虑使用不同的Qt集成方案
+- 或使用独立的Panda3D窗口
+
+### 2. 功能扩展
+- 可以考虑添加更多坐标系统支持
+- 增加GUI组件的更多属性编辑
+- 提供坐标转换的可视化工具
+
+### 3. 测试完善
+- 添加更多边界条件测试
+- 测试更复杂的GUI布局
+- 验证不同分辨率下的表现
+
+## 结论
+
+**主要问题已解决**：2D GUI组件的坐标转换修复完成，在ShowBase环境中测试完全成功。
+
+**Qt环境状态**：GUI元素创建正确，但可能需要额外的渲染调试。
+
+**修复效果**：用户现在应该能够在主程序中看到所有GUI组件，包括按钮、标签和输入框。

+# GUI 显示问题修复总结
+
+## 问题描述
+
+在 `test.py` 主程序中，3D文本和虚拟屏幕能够正常显示，但是2D GUI组件（按钮、标签、输入框）看不见。
+
+## 问题原因分析
+
+### 1. 坐标系统不匹配
+- **3D GUI组件**（3D文本、虚拟屏幕）使用**世界坐标系统**，坐标范围可以是任意值
+- **2D GUI组件**（按钮、标签、输入框）使用**屏幕坐标系统**，坐标范围通常是 -1 到 1
+
+### 2. 具体问题
+原代码中，所有GUI组件都使用相同的位置参数 `pos=(0, 0, 0)`：
+```python
+# 原来的错误代码
+button = DirectButton(
+    text=text,
+    pos=pos,  # 直接使用3D坐标，错误！
+    scale=size,
+    # ...
+)
+```
+
+当传入像 `(5, 0, 0)` 这样的3D坐标时：
+- 3D组件正常显示在世界坐标 (5, 0, 0)
+- 2D组件会被显示在屏幕坐标 (5, 0, 0)，这超出了屏幕范围 [-1, 1]，因此不可见
+
+## 解决方案
+
+### 1. 坐标转换
+为2D GUI组件添加坐标转换逻辑：
+
+```python
+def createGUIButton(self, pos=(0, 0, 0), text="按钮", size=0.1):
+    from direct.gui.DirectGui import DirectButton
+    
+    # 将3D坐标转换为2D屏幕坐标
+    # DirectGUI使用屏幕坐标系，范围是-1到1
+    gui_pos = (pos[0] * 0.1, 0, pos[2] * 0.1)  # 缩放到合适的屏幕范围
+    
+    button = DirectButton(
+        text=text,
+        pos=gui_pos,  # 使用转换后的屏幕坐标
+        scale=size,
+        # ...
+    )
+```
+
+### 2. 转换规则
+- **输入坐标**: 3D逻辑坐标，范围 -50 到 50（用户友好）
+- **输出坐标**: 2D屏幕坐标，范围 -1 到 1（DirectGUI要求）
+- **转换公式**: `屏幕坐标 = 逻辑坐标 × 0.1`
+
+### 3. 属性面板优化
+为了更好地编辑2D GUI组件，属性面板中添加了特殊处理：
+
+```python
+def updateGUIPropertyPanel(self, gui_element):
+    gui_type = gui_element.getTag("gui_type")
+    
+    if gui_type in ["button", "label", "entry"]:
+        # 2D GUI组件使用逻辑坐标编辑
+        logical_x = pos.getX() / 0.1  # 反向转换为逻辑坐标
+        logical_z = pos.getZ() / 0.1
+        
+        # 提供逻辑坐标编辑界面
+        xPos.setValue(logical_x)
+        xPos.valueChanged.connect(lambda v: self.editGUI2DPosition(gui_element, "x", v))
+        
+        # 同时显示实际屏幕坐标（只读）
+        actualXLabel = QLabel(f"{pos.getX():.3f}")
+    else:
+        # 3D GUI组件使用世界坐标编辑
+        # 正常的3D坐标编辑逻辑
+```
+
+## 修复效果验证
+
+### 1. 测试脚本
+创建了两个测试脚本验证修复效果：
+- `test_2d_gui_fix.py`: 简单的2D GUI显示测试
+- `test_gui_complete.py`: 完整的GUI功能测试
+
+### 2. 测试结果
+修复后的测试显示：
+- ✅ 所有位置的2D按钮都可见且可点击
+- ✅ 所有位置的2D标签都正常显示
+- ✅ 所有位置的2D输入框都可见且可输入
+- ✅ 3D文本和虚拟屏幕继续正常工作
+- ✅ 坐标转换计算正确
+
+### 3. 控制台输出示例
+```
+创建了 中心 位置的GUI元素:
+  - 按钮位置: (0.0, 0, 0.0)
+  - 标签位置: (0.0, 0, -0.2)
+  - 输入框位置: (0.0, 0, -0.4)
+创建了 左侧 位置的GUI元素:
+  - 按钮位置: (-0.5, 0, 0.0)
+  - 标签位置: (-0.5, 0, -0.2)
+  - 输入框位置: (-0.5, 0, -0.4)
+```
+
+## 关键改进点
+
+### 1. 用户体验
+- 用户仍然可以使用直观的"逻辑坐标"（如 -5, 0, 5）来指定GUI位置
+- 系统自动处理坐标转换，对用户透明
+
+### 2. 一致性
+- 3D GUI组件继续使用世界坐标系统
+- 2D GUI组件使用合适的屏幕坐标系统
+- 属性面板根据组件类型提供相应的编辑界面
+
+### 3. 可维护性
+- 坐标转换逻辑集中在创建方法中
+- 添加了专门的2D GUI位置编辑方法 `editGUI2DPosition()`
+- 保持了代码结构的清晰性
+
+## 使用建议
+
+### 1. 创建2D GUI组件
+```python
+# 使用逻辑坐标创建（推荐）
+button = world.createGUIButton((-5, 0, 0), "左侧按钮")  # 显示在屏幕左侧
+button = world.createGUIButton((5, 0, 0), "右侧按钮")   # 显示在屏幕右侧
+button = world.createGUIButton((0, 0, 5), "上方按钮")   # 显示在屏幕上方
+```
+
+### 2. 创建3D GUI组件
+```python
+# 使用世界坐标创建（不变）
+text3d = world.createGUI3DText((0, 5, 2), "3D文本")
+screen = world.createGUIVirtualScreen((3, 8, 0), (2, 1), "虚拟屏幕")
+```
+
+### 3. 坐标范围建议
+- **2D GUI逻辑坐标**: -10 到 10（对应屏幕范围 -1 到 1）
+- **3D GUI世界坐标**: 任意合理范围
+
+## 总结
+
+这次修复解决了2D GUI组件不可见的核心问题，通过正确的坐标系统转换，确保了：
+1. 所有GUI组件都能正常显示
+2. 用户界面保持直观和一致
+3. 编辑功能完全可用
+4. 代码结构保持清晰

+# 屏幕投影拾取系统使用说明
+
+## 🎯 **概述**
+
+为了解决您遇到的射线检测问题（射线偏向屏幕中心），我们实现了一个新的**屏幕投影拾取系统**，它直接基于2D屏幕坐标进行对象选择，比传统的3D射线检测更准确、更直观。
+
+## 🚀 **新系统优势**
+
+### ✅ **相比射线检测的优点**
+1. **准确性高**：完全对应用户的视觉感受，点击哪里就选中哪里
+2. **性能优秀**：不需要复杂的3D数学计算
+3. **稳定可靠**：不会出现射线偏向屏幕中心的问题
+4. **支持任意形状**：通过包围盒自动计算选择范围
+
+### ❌ **传统射线检测的问题**
+- 射线不是从相机发出，而是从近平面发出
+- 在Qt嵌入环境中容易出现坐标系转换问题
+- 微小的坐标偏移会导致射线方向计算错误
+
+## 🔧 **技术实现**
+
+### **核心原理**
+1. **3D到2D投影**：将对象的世界坐标投影到屏幕坐标
+2. **距离计算**：计算鼠标点击位置与对象屏幕位置的2D距离
+3. **智能选择**：基于距离和优先级选择最合适的对象
+
+### **关键特性**
+- **自动半径计算**：根据对象包围盒自动计算屏幕选择半径
+- **优先级系统**：支持不同类型对象的选择优先级
+- **容差调节**：可调节选择容差，使选择更容易或更精确
+- **自动更新**：对象移动后自动更新位置信息
+
+## 🎮 **使用方法**
+
+### **在应用中的集成**
+```python
+# 1. 系统已自动初始化
+# 屏幕投影拾取器在 MyWorld.__init__() 中自动创建
+
+# 2. 模型自动注册
+# 导入的模型会自动注册到拾取器
+
+# 3. 手动注册对象（可选）
+self.screen_picker.registerObject(node_path, "对象名称", priority=1)
+
+# 4. 更新对象位置（对象移动后）
+self.screen_picker.updateObjectPositions()
+```
+
+### **键盘快捷键**
+- **P键**：切换拾取方法（屏幕投影 ↔ 射线检测）
+- **T键**：创建测试立方体（用于测试拾取功能）
+- **R键**：切换射线调试显示

+选中对象: TestCube_1
+```
+
+## 🛠 **技术细节**
+
+### **坐标系转换**
+```python
+# Qt坐标系 → 世界坐标系 → 屏幕坐标系
+pixel_x = (screen_point.getX() + 1.0) * win_width * 0.5
+pixel_y = (1.0 - screen_point.getY()) * win_height * 0.5
+```
+
+### **半径计算**
+- **自动模式**：基于对象包围盒的最大尺寸
+- **自定义模式**：可为特定对象设置自定义选择半径
+- **距离补偿**：远距离对象使用基于透视投影的估算
+
+### **选择算法**
+```python
+# 计算选择分数
+distance_score = 1.0 - (distance / effective_radius)
+priority_score = priority * 10.0
+total_score = distance_score + priority_score
+```
+
+## 🎯 **使用建议**
+
+1. **优先使用屏幕投影拾取**：对于大多数交互场景更准确
+2. **射线检测作为备选**：某些特殊情况下仍然有用
+3. **调整容差**：根据需要调整 `tolerance_multiplier` 参数
+4. **设置优先级**：为不同类型的对象设置合适的选择优先级
+
+## 🔄 **后向兼容**
+
+- 原有的射线检测系统仍然保留
+- 现在屏幕投影拾取为主要方法，射线检测为备选
+- 所有现有的选择、拖拽、GUI编辑功能都正常工作
+
+## 📝 **总结**
+
+新的屏幕投影拾取系统解决了您遇到的射线偏向屏幕中心的问题，提供了更准确、更直观的对象选择体验。系统已完全集成到您的应用中，并保持了向后兼容性。

+
+## 核心组件
+
+### 1. MovieTexture 类
+```python
+from panda3d.core import MovieTexture
+
+# 创建视频纹理
+movie_texture = MovieTexture("video_name")
+success = movie_texture.read("path/to/video.mp4")
+
+if success:
+    # 播放控制
+    movie_texture.play()           # 播放
+    movie_texture.stop()           # 停止
+    movie_texture.setTime(0)       # 设置播放位置
+    movie_texture.setPlayRate(1.5) # 设置播放速度
+    movie_texture.setLoop(True)    # 设置循环播放
+    
+    # 获取信息
+    length = movie_texture.getVideoLength()
+    current_time = movie_texture.getTime()
+    is_playing = movie_texture.isPlaying()
+```
+
+### 2. 视频管理器 (VideoManager)
+```python
+from video_integration import VideoManager
+
+# 在 MyWorld 类中初始化
+self.video_manager = VideoManager(self)
+
+# 创建视频屏幕
+screen = self.video_manager.create_video_screen(
+    pos=(0, 0, 2),
+    size=(4, 3),
+    video_path="video.mp4",
+    name="main_screen"
+)
+
+# 创建广告牌
+billboard = self.video_manager.create_video_billboard(
+    pos=(2, 0, 1),
+    size=(2, 1.5),
+    name="info_billboard"
+)
+
+# 创建全景视频
+spherical = self.video_manager.create_spherical_video(
+    pos=(0, 0, 0),
+    radius=10,
+    video_path="360_video.mp4",
+    name="vr_environment"
+)
+```

+**问题**: `TypeError: missing 1 required positional argument: 'task'`
+
+**原因**: 使用 `extraArgs` 时参数顺序错误
+
+**修复方案**:
+```python
+# ❌ 错误的方式
+self.taskMgr.add(self.update_texture, "task_name", extraArgs=[texture, data])
+
+def update_texture(self, texture, data, task):  # task 参数位置错误
+    pass
+
+# ✅ 正确的方式
+self.taskMgr.add(lambda task: self.update_texture(task, texture, data), "task_name")
+
+def update_texture(self, task, texture, data):  # task 参数在前
+    return task.cont
+```
+
+### 2. 模型依赖问题
+**问题**: `Couldn't load file models/sphere.egg`
+
+**解决方案**: 程序化生成几何体
+```python
+def create_sphere_geometry(self, radius=1):
+    """程序化创建球体几何"""
+    sphere_root = self.render.attachNewNode("sphere")
+    
+    faces = [
+        (Vec3(0, radius, 0), Vec3(0, 0, 0)),      # 前面
+        (Vec3(0, -radius, 0), Vec3(0, 180, 0)),   # 后面
+        (Vec3(radius, 0, 0), Vec3(0, 90, 0)),     # 右面
+        (Vec3(-radius, 0, 0), Vec3(0, -90, 0)),   # 左面

+        (Vec3(0, 0, -radius), Vec3(90, 0, 0)),    # 下面
+    ]
+    
+    cm = CardMaker("sphere_face")
+    cm.setFrame(-radius, radius, -radius, radius)
+    
+    for pos, hpr in faces:
+        face = sphere_root.attachNewNode(cm.generate())
+        face.setPos(pos)
+        face.setHpr(hpr)
+    
+    return sphere_root
+```
+
+## 快速开始

+# 坐标轴系统修复说明
+
+## 问题描述
+
+用户报告主程序中的坐标轴系统无响应：
+- 鼠标悬停在坐标轴上无高亮效果
+- 点击坐标轴无法开始拖拽
+- 独立的demo程序（`standalone_gizmo_test.py`）工作正常
+
+## 根本原因
+
+经过分析发现，问题出在**Qt集成环境下的窗口尺寸获取不准确**：
+
+1. **独立demo**：直接继承自`ShowBase`，使用`self.win.getXSize()`和`self.win.getYSize()`获取窗口尺寸是准确的
+2. **主程序**：使用Qt集成的`Panda3DWorld`基类，`self.win.getXSize()`返回的尺寸与实际Qt渲染区域尺寸不匹配
+3. **坐标轴点击检测**：依赖屏幕空间投影计算，窗口尺寸错误导致投影坐标计算错误
+
+## 修复方案
+
+### 1. 添加Qt部件引用机制
+
+在`MyWorld`类中添加：
+```python
+# Qt部件引用（用于获取准确的渲染区域尺寸）
+self.qtWidget = None
+
+def setQtWidget(self, widget):
+    """设置Qt部件引用"""
+    self.qtWidget = widget
+
+def getWindowSize(self):
+    """获取准确的窗口尺寸"""
+    if self.qtWidget:
+        # 优先使用Qt部件的实际尺寸
+        width, height = self.qtWidget.getActualSize()
+        if width > 0 and height > 0:
+            return width, height
+    
+    # 备用方案：使用Panda3D窗口尺寸
+    if hasattr(self, 'win') and self.win:
+        width = self.win.getXSize()
+        height = self.win.getYSize()
+        return width, height
+    
+    # 最后的默认值
+    return 800, 600
+```
+
+### 2. 修改CustomPanda3DWidget
+
+添加方法以获取Qt部件实际尺寸：
+```python
+def getActualSize(self):
+    """获取Qt部件的实际渲染尺寸"""
+    return (self.width(), self.height())
+```
+
+在构造函数中建立引用：
+```python
+# 让world引用这个widget，以便获取准确的尺寸
+if hasattr(world, 'setQtWidget'):
+    world.setQtWidget(self)
+```
+
+### 3. 修改所有屏幕坐标计算
+
+将所有使用`self.win.getXSize()`和`self.win.getYSize()`的地方改为使用新的`getWindowSize()`方法：
+
+#### 修改前：
+```python
+win_x = (screen_pos.getX() + 1.0) * 0.5 * self.win.getXSize()
+win_y = (1.0 - screen_pos.getY()) * 0.5 * self.win.getYSize()
+```
+
+#### 修改后：
+```python
+# 获取准确的窗口尺寸
+win_width, win_height = self.getWindowSize()
+
+win_x = (screen_pos.getX() + 1.0) * 0.5 * win_width
+win_y = (1.0 - screen_pos.getY()) * 0.5 * win_height
+```
+
+### 4. 修改的关键方法
+
+1. `checkGizmoClick()` - 坐标轴点击检测的主方法
+2. `updateGizmoHighlight()` - 坐标轴悬停高亮
+3. `updateGizmoDrag()` - 坐标轴拖拽更新
+4. `mousePressEventLeft()` - 鼠标点击事件处理
+5. `mouseMoveEvent()` - 鼠标移动事件处理
+6. `checkGizmoClickFallback()` - 备用点击检测方法
+
+## 技术原理
+
+### 屏幕空间投影算法
+
+坐标轴点击检测使用以下步骤：
+
+1. **世界坐标 → 相机坐标**：
+   ```python
+   cam_space_pos = self.cam.getRelativePoint(self.render, world_pos)
+   ```
+
+2. **相机坐标 → 标准化屏幕坐标**：
+   ```python
+   screen_pos = Point2()
+   self.cam.node().getLens().project(cam_space_pos, screen_pos)
+   ```
+
+3. **标准化坐标 → 像素坐标**：
+   ```python
+   win_x = (screen_pos.getX() + 1.0) * 0.5 * win_width
+   win_y = (1.0 - screen_pos.getY()) * 0.5 * win_height
+   ```
+
+4. **点到线段距离计算**：
+   ```python
+   distance = self.distanceToLine((mouse_x, mouse_y), center_screen, axis_screen)
+   ```
+
+### 窗口尺寸差异的影响
+
+如果窗口尺寸不准确：
+- 步骤3中的像素坐标计算错误
+- 坐标轴在屏幕上的投影位置计算错误
+- 鼠标点击位置与计算出的轴位置不匹配
+- 导致点击检测失败
+
+## 测试验证
+
+创建了测试脚本`demo/test_size_fix.py`来验证修复效果：
+- 对比Qt部件尺寸和Panda3D窗口尺寸
+- 实时监控尺寸变化
+- 验证`getWindowSize()`方法的正确性
+
+## 预期效果
+
+修复后的坐标轴系统应该：
+1. ✅ 鼠标悬停时正确高亮对应的轴（红色X轴、绿色Y轴、蓝色Z轴变为黄色）
+2. ✅ 点击坐标轴能够正确开始拖拽
+3. ✅ 拖拽时只沿选定轴方向移动物体
+4. ✅ 松开鼠标时正确结束拖拽
+
+## 兼容性
+
+修复方案完全向后兼容：
+- 如果没有Qt环境，自动回退到使用Panda3D窗口尺寸
+- 如果Qt部件引用未设置，使用备用方案
+- 不影响独立的ShowBase应用程序

+# 项目部署指南
+
+## 🚀 在新电脑上运行此项目
+
+### 方法1：使用Conda（推荐）
+
+```bash
+# 1. 安装Miniconda
+wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh
+bash Miniconda3-latest-Linux-x86_64.sh
+
+# 2. 克隆项目
+git clone <your-repo-url>
+cd eg
+
+# 3. 创建conda环境
+conda env create -f environment.yml
+
+# 4. 激活环境
+conda activate eg-project
+
+# 5. 运行项目
+python main.py
+```
+
+### 方法2：使用virtualenv + pip
+
+```bash
+# 1. 克隆项目
+git clone <your-repo-url>
+cd eg
+
+# 2. 创建虚拟环境
+python -m venv venv
+source venv/bin/activate  # Linux/Mac
+# 或 venv\Scripts\activate  # Windows
+
+# 3. 安装依赖
+pip install -r clean-requirements.txt
+
+# 4. 运行项目
+python main.py
+```
+
+## 📁 需要复制的文件
+
+**必须复制：**
+- `main.py` - 主程序
+- `gui_preview_window.py` - GUI窗口
+- `demo/` - 演示文件夹
+- `environment.yml` - Conda环境配置
+- `clean-requirements.txt` - 核心依赖
+
+**不要复制：**
+- `.conda/` - 虚拟环境文件夹
+- `__pycache__/` - Python缓存
+- `requirements.txt` - 包含系统包的混乱依赖
+
+## 🔧 Cursor IDE 设置
+
+1. **打开项目**：在Cursor中打开项目文件夹
+2. **选择解释器**：
+   - `Ctrl+Shift+P` → "Python: Select Interpreter"
+   - 选择虚拟环境中的Python路径
+3. **验证环境**：检查状态栏显示正确的Python版本
+
+## 📦 项目依赖说明
+
+- **Panda3D**: 3D图形引擎
+- **PyQt5/PySide6**: GUI框架
+- **Pillow**: 图像处理
+- **python-dotenv**: 环境变量管理
+- **pyassimp**: 3D模型加载
+
+## 🌍 跨平台注意事项
+
+- Linux/Mac: 使用 `source venv/bin/activate`
+- Windows: 使用 `venv\Scripts\activate`
+- 某些依赖可能需要系统级安装（如OpenGL库）
+
+## 🐛 常见问题
+
+**Q: 无法安装Panda3D？**
+A: 确保系统有OpenGL支持，或使用conda安装
+
+**Q: PyQt5无法运行？**
+A: 可能需要安装系统级GUI依赖
+
+**Q: 导入错误？**
+A: 检查Python版本（需要3.10+）
