示例：

3dmm. python 2_3dmm.py

left: random example generated by 3dmm

right: fitting face with 3dmm using 68 key points

transform. python 3_transform.py
left:

fix camera position & use orthographic projection. (often used in reconstruction)

then transform face object: scale, change pitch angle, change yaw angle, change roll angle

right:

fix obj position & use perspective projection(fovy=30). (simulating real views)

then move camera position and rotate camera: from far to near, down & up, left & right, ro
