Description: The non-linear color space is a fundamental concept in 3D rendering that refers to a model of color representation where the relationship between color values does not follow a linear progression. In this type of space, colors are represented in such a way that changes in input values do not translate into proportional changes in visual perception. This is especially relevant in the context of lighting and visualization, where human perception of light and color is not linear. For example, the human eye is more sensitive to changes in shadows and low lights than to changes in bright lights. Therefore, using a non-linear color space allows for a more accurate and realistic representation of scenes, enhancing the visual quality of generated images. This approach is crucial in computer graphics applications, where a faithful representation of reality is sought. Non-linear color spaces, such as sRGB or gamma color space, are widely used in image and video production, as they allow for better dynamic range management and a richer representation of colors compared to linear spaces.
