mvs一镜到底

一、Use smart-unwrap to create uv coordinates and store your mesh as .obj file.

1. smart-unwrap

删除所有对象，包括灯光和相机，导入.obj。
Tab+A+U

2. store your mesh as .obj file.

3. 关闭blender

二、grayscales rendering and viepoints’ rotation and tranlation matrices.

1. 添加运动轨迹

2. 添加相机约束

按Alt+G

3. 调整相机视角至合适位置，并修改焦距

4. 修改帧范围，默认100帧转一圈

5. 添加材质

6. 设置渲染引擎

7. 修改对象名称，输出路径，输出格式
