Data Conventions¶
Coordinate Conventions¶
The camera poses stored in transforms.json files follow Blender/OpenGL/NeRF camera conventions where +X is right, +Y is up, and +Z is pointing back and away from the camera, making the camera’s viewing direction -Z. Another common convention is the OpenCV/COLMAP convention, which uses the same X axis, with +Y going down and +Z going into the scene.
