 # 中国石化加油站项目
 
+## 🌼v1.1.0
+
+### 🌻 简介
+
+> 时间：2022、1、22 周六
+> 优化加载
+> 增加镜头限制、增加吸附功能
+
+### 🌻 详情
+
+> 前端部分
+
+- [🚩 重大变更]
+- [🌱 新增]
+- [🍀 完善]
+
+> 三维部分
+
+- [🚩 重大变更] 增加对关联复制模型的支持，可以大幅减少 bin 文件的大小，增加解析速度与渲染速度
+- [🚩 重大变更] 暂时停止 1+n 的模型加载模式（indexDB 问题以在另外的地方进行解决），充分利用并发加载
+- [🌱 新增] 摄像头旋转时设置限制，避免看到场景的底部
+- [🌱 新增] 增加建筑吸附、对齐到场景中的功能，确定对齐规则，使用“WAI”节点作为插槽
+- [🍀 完善]
+
 ## 🌼v1.0.9
