* Data format.
* Each scene consists of 3 splits: train/test/validation.
* Intrinsics and poses are stored as flattened 4x4 matrices (row-major).
* Pixel coordinate of an image's upper-left corner is (column, row)=(0, 0).
* Pixel coordinate of an image's upper-left corner is (column, row)=(0, 0), lower-right corner is (width-1, height-1).
* Poses are camera-to-world, not world-to-camera transformations.
* Opencv camera coordinate system is adopted, i.e., x--->right, y--->down, z--->scene.
* To convert camera poses between Opencv and Opengl conventions, the following code snippet can be used for both Opengl2Opencv and Opencv2Opengl.
