Viewpoints issue

[achichichi]

Dear @peteanderson80 ,
Thank you for your excellent contribution!
Reading your code (utils.py), I have some confuse about the viewpoint position. I found that the information about the position of all nodes in the scan is " ['pose'][3],['pose'][7],['pose'][11]. Could you explain about how to get the coordinate of all nodes in the scan ? Thanks so much!

I have the same confusion about variable pose. According to file Readme.md, ``pose: 4x4 matrix in row major order that transforms matterport skyboxes to global coordinates (z-up). Pose matrices are based on the assumption that the camera is facing skybox image 3. It seems only ` ['pose'][3],['pose'][7],['pose'][11]` was used in the code. Does this means ` ['pose'][3],['pose'][7],['pose'][11]` is the x-axis,y-axis,z-axis of the three-dimensions ? If it is,what is others in the `pose`?
