Det \u00e4r en process d\u00e4r man tar bort de ytor i ett 3D-objekt som inte \u00e4r synliga f\u00f6r betraktaren. Tekniken bygger p\u00e5 principen att ett ansikte bara \u00e4r synligt om dess normalvektor pekar mot betraktaren.<\/p>\n<p>N\u00e4r ett 3D-objekt renderas kontrolleras varje yta p\u00e5 objektet f\u00f6r att se om den \u00e4r v\u00e4nd mot betraktaren eller bort fr\u00e5n betraktaren. Om en yta \u00e4r v\u00e4nd bort fr\u00e5n betraktaren kasseras den och renderingsmotorn g\u00e5r vidare till n\u00e4sta yta. Den h\u00e4r processen kallas back face culling.<\/p>\n<p>Back face culling \u00e4r en viktig teknik som anv\u00e4nds inom 3D-grafik eftersom den avsev\u00e4rt kan f\u00f6rb\u00e4ttra prestandan i renderingsprocessen. Genom att ta bort de ansikten som inte \u00e4r synliga kan renderingsmotorn fokusera p\u00e5 att bara rendera de synliga ansiktena, vilket minskar antalet ber\u00e4kningar som kr\u00e4vs f\u00f6r att rendera en scen. Detta minskar i sin tur den tid det tar att rendera en scen, vilket g\u00f6r renderingsprocessen mer effektiv.<\/p>\n<p>Back face culling anv\u00e4nds i m\u00e5nga 3D-grafikapplikationer, inklusive videospel, virtual reality och datorst\u00f6dd design (<a href=\"https:\/\/thecodest.co\/sv\/dictionary\/computer-aided-design-cad\/\">CAD<\/a>) programvara.
