glm::luminosity
GLM_FUNC_DECL T luminosity(vec< 3, T, Q > const &color)
Compute color luminosity associating ratios (0.33, 0.59, 0.11) to RGB canals.
glm::hsvColor
GLM_FUNC_DECL vec< 3, T, Q > hsvColor(vec< 3, T, Q > const &rgbValue)
Converts a color from RGB color space to its color in HSV color space.
glm::rgbColor
GLM_FUNC_DECL vec< 3, T, Q > rgbColor(vec< 3, T, Q > const &hsvValue)
Converts a color from HSV color space to its color in RGB color space.
glm::saturation
GLM_FUNC_DECL vec< 4, T, Q > saturation(T const s, vec< 4, T, Q > const &color)
Modify the saturation of a color.
