Abstract:
In a technique for rendering non-linear BRDFs that are stable in both the temporal and spatial domains, without serious interruption to the content creation pipeline used in most games, non-linear content is linearized by rendering in texture space at a fixed resolution. A MIP-map chain is calculated from this texture. The complete MIP-map chain is used for rendering on a display device. Low resolution reflectance parameters are used to approximate the highest resolution reflectance parameters as the object becomes smaller on the display device. The low resolution reflectance parameters are calculated using non linear fitting techniques.
