I saw in the other discussion a breakdown of the frame durations we can use for 18k cubemaps in the new OrbX player. It was mentioned that the duration limitation had to do with RAM usage. It stands to reason that if we don't show the full 360 degrees we would be able to have a longer duration for our animations. However what if we don't want to limit ourselves to selecting which faces of the cubemap to render... if we pick just the front faces we don't have enough FOV, and if we pick everything but the back face we're not saving much space. If we use an alpha to cut out wherever we decide to limit the FOV will that give us gains in duration?
I'm thinking maybe figure out something at about 200 degrees where you have a full view wherever you turn your head, but if you actually turn your body you would see the edge of the matte. The downfall would be if the alpha actually adds more size per frame than it gains. On that note does adding black to the animation have the same effect as alpha since we're cutting down the number of pixels?
Let me know if anyone has tested this.
