Abstract

A method for calculating a lighting function for an object to be rendered using a basis function is provided. The method includes calculating a transfer function approximation of the lighting function through a stream processor. A method for presenting lighting characteristics associated with a display object in real-time and a method for determining secondary illumination features for an object to be displayed are also provided. A computer readable medium and a computing device having a graphics processing unit capable of determining lighting characteristics for an object in real time are also included.
