Abstract[English]
There is described a method of shading a group of pixels in a fragment shader in a raster graphics pipeline. At least one first pilot pixel of the group of pixels is shaded under a first precision. At least one second pilot pixel of the group of pixels is shaded under a second precision. An error value representing a difference between the first and second pilot pixels is calculated. At least one other pixel of the group of pixels is shaded under the first precision if the error value is greater than an error threshold. The at least one other pixel is shaded under the second precision if the error value is smaller than the error threshold.[French]
L'invention décrit un procédé d'ombrage d'un groupe de pixels dans un nuanceur de fragments dans un pipeline graphique de trame. Au moins un premier pixel pilote du groupe de pixels est ombré selon une première précision. Au moins un second pixel pilote du groupe de pixels est ombré selon une seconde précision. Une valeur d'erreur représentant une différence entre les premier et second pixels pilotes est calculée. Au moins un autre pixel du groupe de pixels est ombré selon la première précision si la valeur d'erreur est supérieure à un seuil d'erreur. Le ou les autres pixels sont ombrés selon la seconde précision si la valeur d'erreur est inférieure au seuil d'erreur.
