1. A computer-implemented method for rendering one or more graphics images, the method comprising:
sampling a plurality of directions of light passing through a slab medium;
computing one or more parameters associated with one or more position distributions based on the plurality of directions of light;
computing a brightness in a direction at which the light exits a plurality of portions of a first surface of the slab medium based on the one or more parameters associated with the one or more position distributions and based on the direction at which the light exits the plurality of portions of the first surface of the slab medium; and
rendering the one or more graphics images based on the brightness in the direction at which the light exits the plurality of portions of the first surface of the slab medium.
