facet culling
Technical term in computer graphics: a rendering optimization that skips drawing polygons facing away from the camera.
In 3D games, facet culling reduces the rendering load.
Synonymous loanword from English 'back-face culling', more common in some technical contexts.
Compound of 小面 (small face/polygon) and 除去 (removal), directly describing the removal of small or back-facing polygons.
