Abstract
The invention relates to a method for estimating the quantity of light scattered by a heterogeneous participating media. In order to optimise the display while minimising the required calculation time, the method comprises steps for selecting at least one level of spatial subdivision of said media from among a plurality of hierarchic levels of spatial subdivision according to at least one item of error information representative of an attenuation difference in said media according to at least one direction between two consecutive hierarchic levels, and estimating the quantity of light scattered by sampling of said media along at least one scattering direction, the sampling being a function of at least one selected spatial subdivision level.
