The Math You Need to Pan and Tilt 360° Images

Panning and tilting 360-degree spherical images requires a specific mathematical approach, particularly for the equirectangular format. Modifying the camera pose is achieved by applying rotation matrices based on spherical coordinates to define the desired angular shift. The core technique involves calculating a reverse transform, which maps pixels from the target (output) image back to the source (input) image. This remapping process ensures that the new image is correctly populated by interpolating pixel values, preventing holes or distortions.
