Power Gamerz heeft een paar vragen gesteld aan Nick Triantos van nVidia. Hieronder vast een klein gedeelte, hier staat de rest.
PG: Dealing with Cube Environment Mapping, could this be considered a more advanced version of the environmental bump mapping seen in the latest Matrox offerings? Will it create the same type of visuals, albeit better than standard Environment Mapping?Nick: No, actually, cube environment mapping is a really cool way of making reflections. There are some software renderers I've seen that do spherical environment mapping, but the problem with that is that you get "singularities", or points on the sphere where the image looks kind of pinched. It would be like taking a nice flat picture of the Earth and trying to wrap it onto a sphere. At the North Pole and South Pole, you'd have a bunch of extra paper. Cube environment mapping solves that problem nicely, by placing the reflected object inside a cube instead of a sphere. The visual difference is really noticeable. Cube environment mapping kicks booty over spherical env mapping.
