Cubic projection type 3 – Cruciform

In cubic projection, the image is mapped onto the inside of a cube.  Straight lines remain straight except where they cross from one cube face to another.  The curciform cubic format arranges the 6 cube faces in a cross shape as though the cube was simply unfolded.

·         The Panorama Factory can convert to and from this format.

·         Suitable for full circle panoramas but can give surprising results for partial panoramas between 270 and 360 degrees..

·         Poor for image processing because of discontinuous faces.

·         Exports to cubic QTVR format.

·         Does not export to PTViewer format.

·         Makes more intuitive sense than the other cubic format.

·         Can be suitable for printing as a special effect.
