ABSTRACT:
An image rendering method for a computer system includes identifying a point in space to be illuminated from at least one line light for the point, and determining an illumination direction of the line light. The method further includes generating a plane passing through the point, and projecting the line light onto the plane. The method further includes determining a brightness contribution for the point responsive to a function characterizing the brightness contribution.
