noun
normalized projection coordinates; NPC
Technical term in computer graphics; refers to the coordinate system after perspective division, where coordinates are normalized to a standard range (e.g., [-1,1] or [0,1]).
正規化投影座標系では、クリッピング空間の座標がwで除算された後、正規化された範囲にマッピングされる。
In normalized projection coordinates, the coordinates in clip space are divided by w and then mapped to a normalized range.
Clipping coordinates are the coordinates before perspective division; normalized projection coordinates are obtained after dividing by w.
Screen coordinates are the final pixel coordinates after viewport transformation, while normalized projection coordinates are an intermediate normalized space.
Compound of 正規化 (normalization), 投影 (projection), and 座標系 (coordinate system). A direct translation of the English term 'normalized projection coordinates'.
