Camera and World Coordinate in Blender Dataset #120

Hi,

I am trying to generate my own viewing points on blender dataset, but I can't find any reference of how to generate the transformation matrix. I tried several possible ways, but it seems the [x,y,z] coordinate directions are different in World and Camera frames. Can you tell me how to generate my own transformation matrix of new viewing points?

Sincerely thanks!

I'm struggling with camera transformation matrices too. You may find this python-blender script by the authors useful to generate your poses: https://github.com/bmild/nerf/issues/78#issuecomment-710179139
