>>10404833A technique where you take borderline (clothed) nudity and censor the clothes using circles, your brain fills in the empty areas to become similar to proper nudity. Naturally the closer to nudity the better it works, and poses which would not hide the important bits of unclothed also work best.
The 3D version of it would be using props, which are obviously not part of the figure, to cover the clothed areas.
