Coordinate relation of input image plane and generated glb

[yosun]

If one uses a plane to display the input image, which coordinate position would that fit in, in the final generated glb?

Hi! The glb follows the convention of OpenGL identity camera coordinate system, +x right, +y up, +z backward. (The raw output point map follows the OpenCV convention, +x right, +y down, +z forward. It is converted to OpenGL convention when exported as glb files.) The image plane in the OpenGL coordinate system is z=-1 plane.
