The list of methods on the top left corresponds one-to-one to the rows in Table 1 in the OmniPhotos
paper.
The images and proxy renderings are created by rendering cubemap faces at 512×512 resolution, and
converting the cubemap to an equirectangular image at 1536×768 resolution using skylibs.
The proxy renderings visualise the world-space positions of the proxy geometry. The red/green/blue lines
indicate where the geometry intersects the planes {x, y, z} = k × 40 cm (for
integer k). For example, green lines indicate horizontal planes (perpendicular to the y-axis)
that are spaced 40 cm apart.
The Parallax360 rendering is not continuous across cubemap faces and thus shows stitching errors.
