/// 陶艺制作器 - PotteryMaker.cs
/// ============================================================================
/// 
/// 【功能概述】
/// 专业的3D陶器建模工具，支持实时交互式陶器制作和编辑
/// 
/// 【主要特性】
/// ✅ 智能网格生成 - 自动创建底部、外壁、顶部、内壁和内底网格
/// ✅ 双模式操作   - 左键扩大陶器，右键缩小陶器
/// ✅ 高度补偿系统 - 壁扩大时自动变矮，壁缩小时自动变高
/// ✅ 实时碰撞器   - 动态更新网格碰撞器，支持触发器模式
/// ✅ 调试可视化   - 显示影响范围和操作目标点
/// ✅ 多输入支持   - 同时支持鼠标和触控输入
/// 
/// 【操作指南】
/// 1. 左键拖拽：扩大陶器形状
/// 2. 右键拖拽：缩小陶器形状  
/// 3. 垂直拖拽：调整整体高度
/// 4. 参数调整：在Inspector中修改模型参数
/// 
/// 【快捷键】
/// • 左键 + 水平拖拽：半径调整
/// • 右键 + 水平拖拽：反向半径调整
/// • 任何键 + 垂直拖拽：高度调整
/// 
/// 【注意事项】
/// • 确保已分配陶艺材质
/// • 碰撞器默认启用，可根据需要调整
/// • 调试信息可在编辑器中查看操作效果
