摘要
Shadow images, which are formed on a light-receiving surface by occluding light emitted from a light source with at least one occluding surface, are drawn by the generating data representative of brightness discontinuity edges that partition the light-receiving surface into loop areas that are completely occluded by the occluding surface and loop areas that are partially or totally irradiated by the light source. An irradiation state is assigned to each loop area. The loop areas are then divided into meshes according to the irradiation state assigned to the loop area. Pixel data is generated for each element of the mesh and output for display on a display device.
