Title
(EN) METHOD AND SYSTEM FOR RENDERING
(FR) PROCÉDÉ ET SYSTÈME DE RENDU
Abstract
(EN) A computer-implemented method for rendering is provided. The method comprises: receiving a first set of tristimulus values representing a first colour in a colour space; determining a first approximation of the first colour based on at least one first reflectance coefficient representing a second colour; determining a second approximation of the first colour based on at least one second reflectance coefficient and at least one fluorescent coefficient representing the second colour; and storing either the first approximation of the first colour or the second approximation of the first colour as the first colour in a renderer.
(FR) L'invention concerne un procédé mis en œuvre par ordinateur destiné à la réalisation d'un rendu. Le procédé consiste : à recevoir un premier ensemble de valeurs trichromatiques représentant une première couleur dans un espace de couleurs; à déterminer une première approximation de la première couleur en fonction d'au moins un premier coefficient de réflectance représentant une seconde couleur; à déterminer une seconde approximation de la première couleur en fonction d'au moins un second coefficient de réflectance et d'au moins un coefficient de fluorescence représentant la seconde couleur; et à stocker soit la première approximation de la première couleur, soit la seconde approximation de la première couleur en tant que première couleur dans un moteur de rendu.
