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. .. figure:: ../_static/camera-conventions.png :width: 85% Camera coordinate conventions (`source `_)
