FAQ

What coordinate system does the "transform_train.json" use to represent camera location and their relative transformation?

We use the OpenGL/Blender (and original NeRF) coordinate convention for cameras. +X is right, +Y is up, and +Z is pointing back and away from the camera. -Z is the look-at direction. Please refer to this post for more information.
