Abstract : We present a multiscale surface appearance representation and a rendering model that accounts for the subpixel visibility distribution. Starting from this model, we propose a method for pre-filtering detailed surfaces and their attributes. Our representation of the filtered attributes takes the correlation with their visibility into account. The masking and shadowing effects lost in geometric filtering of the surface can thus be recovered at rendering. This grants high visual quality of subpixel effects while ensuring a nearly constant per pixel computation complexity. Besides, accounting for subpixel occlusion naturally anti-aliases geometry. The computational model we propose has low memory and computational time requirements, and is thus well-suited for real-time rendering.
