I’m presently researching the distinction between Dice Mapping and Spherical Mapping.
Wikipedia says the next:
Within the majority of circumstances, dice mapping is most well-liked over the older technique of sphere mapping as a result of it eliminates lots of the issues which can be inherent in sphere mapping similar to picture distortion, viewpoint dependency, and computational inefficiency. Additionally, dice mapping offers a a lot bigger capability to assist real-time rendering of reflections relative to sphere mapping as a result of the mixture of inefficiency and viewpoint dependency severely limits the power of sphere mapping to be utilized when there’s a persistently altering viewpoint.
How are dice maps NOT viewpoint dependent?
And does this indicate that just about in each case Spherical Maps will be changed by Dice Maps? Or are there exceptions? (some examples can be good)

Relating to reflections:
Dice-maps are capturing the entire reflection area across the pivot on the dice, whatever the digicam’s going through route. Whereas spherical maps seize solely the area that’s going through the digicam (and therefore the map must be re-drawn for every viewing route)
