二、知识基础：3D翻转效果的核心原理与实现逻辑

在展示完整代码之前，我们需要深入理解3D翻转效果的核心原理和实现逻辑。掌握这些基础知识后，你将能够举一反三应对各种3D翻转效果相关的开发需求。

1. 3D翻转效果的基本原理

3D翻转效果通过使用CSS 3D变换，实现元素在三维空间中的翻转：

// 3D翻转效果核心原理
// 1. 使用 transform 属性实现3D变换
// 2. 使用 rotateX/rotateY 实现旋转
// 3. 使用 perspective 设置透视距离
// 4. 使用 backfaceVisibility 控制背面可见性

// 基础3D翻转实现
const FlipBase = () => {
  const [isFlipped, setIsFlipped] = useState(false);

  return (
    <View style={styles.flipContainer}>
      <View
        style={[
          styles.flipCard,
          { transform: [{ rotateY: isFlipped ? '180deg' : '0deg' }] },
        ]}
      >
        <View style={styles.flipFront}>
          <Text>正面</Text>
        </View>
        <View style={styles.flipBack}>
          <Text>背面</Text>
        </View>
      </View>
      <TouchableOpacity onPress={() => setIsFlipped(!isFlipped)}>
        <Text>点击翻转</Text>
      </TouchableOpacity>
    </View>
  );
};

核心要点：

• 使用 transform 实现变换
• rotateX/rotateY 控制旋转
• perspective 设置透视
• backfaceVisibility 控制背面

2. 水平翻转效果

实现水平方向的翻转效果：

const HorizontalFlip = () => {
  const [isFlipped, setIsFlipped] = useState(false);

  return (
    <View style={styles.flipContainer}>
      <View
        style={[
          styles.flipCard,
          { transform: [{ rotateY: isFlipped ? '180deg' : '0deg' }] },
        ]}
      >
        <View style={styles.flipFront}>
          <Text>正面内容</Text>
        </View>
        <View style={styles.flipBack}>
          <Text>背面内容</Text>
        </View>
      </View>
      <TouchableOpacity onPress={() => setIsFlipped(!isFlipped)}>
        <Text>水平翻转</Text>
      </TouchableOpacity>
    </View>
  );
};

核心要点：

• 使用 rotateY 实现水平翻转
• 正面和背面分别渲染
• 通过状态控制翻转
• 适用于卡片设计

3. 垂直翻转效果

实现垂直方向的翻转效果：

const VerticalFlip = () => {
  const [isFlipped, setIsFlipped] = useState(false);

  return (
    <View style={styles.flipContainer}>
      <View
        style={[
          styles.flipCard,
          { transform: [{ rotateX: isFlipped ? '180deg' : '0deg' }] },
        ]}
      >
        <View style={styles.flipFront}>
          <Text>正面内容</Text>
        </View>
        <View style={styles.flipBack}>
          <Text>背面内容</Text>
        </View>
      </View>
      <TouchableOpacity onPress={() => setIsFlipped(!isFlipped)}>
        <Text>垂直翻转</Text>
      </TouchableOpacity>
    </View>
  );
};

核心要点：

• 使用 rotateX 实现垂直翻转
• 正面和背面分别渲染
• 通过状态控制翻转
• 适用于上下翻页效果

4. 卡片翻转效果

实现类似卡片的翻转效果：

const CardFlip = () => {
  const [isFlipped, setIsFlipped] = useState(false);

  return (
    <View style={styles.cardFlipContainer}>
      <View
        style={[
          styles.cardFlip,
          { transform: [{ rotateY: isFlipped ? '180deg' : '0deg' }] },
        ]}
      >
        <View style={styles.cardFlipFront}>
          <Text style={styles.cardFlipTitle}>卡片正面</Text>
          <Text style={styles.cardFlipDescription}>这是卡片的正面内容</Text>
        </View>
        <View style={styles.cardFlipBack}>
          <Text style={styles.cardFlipTitle}>卡片背面</Text>
          <Text style={styles.cardFlipDescription}>这是卡片的背面内容</Text>
        </View>
      </View>
      <TouchableOpacity
        style={styles.cardFlipButton}
        onPress={() => setIsFlipped(!isFlipped)}
      >
        <Text style={styles.cardFlipButtonText}>翻转卡片</Text>
      </TouchableOpacity>
    </View>
  );
};

核心要点：

• 使用 rotateY 实现翻转
• 正面和背面有完整内容
• 添加阴影增加立体感
• 适用于信息展示

5. 循环翻转效果

实现自动循环的翻转效果：

const LoopFlip = () => {
  const [rotation, setRotation] = useState(0);

  useEffect(() => {
    const animate = () => {
      setRotation(prev => prev + 1);
      requestAnimationFrame(animate);
    };
    animate();
  }, []);

  return (
    <View style={styles.loopFlipContainer}>
      <View
        style={[
          styles.loopFlipCard,
          { transform: [{ rotateY: `${rotation}deg` }] },
        ]}
      >
        <Text>循环翻转</Text>
      </View>
    </View>
  );
};

核心要点：

• 持续增加旋转角度
• 使用 requestAnimationFrame
• 无限循环播放
• 适用于加载动画
