back face culling
Back Face Culling means the removal of back faces. It is a technique used in 3D graphics that eliminates parts of the image that are not visible.
In back face culling, polygons that are not visible from the viewer are not rendered and displayed. This saves computing power, reduces the number of polygons and data volume, and increases performance and rendering speed.
In addition to the back face culling technique, there are other culling methods: view frustum culling, in which only the objects that lie within the viewing cone are calculated, detail culling, and occlusion culling, in which hidden objects are not included in the graphical calculation.
