With a total of 2 patents to his name, Bavoil's work has influenced the way light and shadows are rendered in digital images.

Latest Patents

One of Bavoil's latest patents is focused on "Cone-culled soft shadows." This innovation addresses the creation of soft shadows in computer graphics images by rendering scenes from both the camera viewpoint and at least one light viewpoint. The method involves storing the positions of scene fragments and light fragments within the scene. For each scene fragment, a frustum is defined between the position of the scene fragment and the light source. Light fragments are then evaluated concerning the frustum to identify those that block light between the light source and the scene fragment. A shading value, either color or monochromatic, is determined for each scene fragment, indicating the amount of light blocked or transmitted by the light fragments. These shading values are subsequently used to modify the scene fragments accordingly. This technique allows for the creation of computer graphics images with soft shadows, utilizing either a graphics processing subsystem alone or in conjunction with a central processing unit through a pipelined, deferred shading approach.
