Bruit de Perlin
Image générée par bruit de Perlin
Le bruit de Perlin est une texture procédurale utilisée comme effet visuel pour augmenter le réalisme apparent dans la synthèse d'image. La fonction a une apparence pseudo-aléatoire, et pourtant tous ses détails visuels sont de taille égale (voir image). Cette propriété permet à cette texture d'être facilement contrôlable. De multiples copies zoomées de bruit de Perlin peuvent être insérées dans des expressions mathématiques pour créer une grand variété de textures procédurales.
