发明名称 Computer graphics method for adding specular reflections to images with shadow penumbrae.
摘要 <p>A computer graphics method adds shadowed specular highlights to computer generated images by modifying the specular reflection value (SRi) for each vertex (V) in the scene according to the value of a corresponding illumination coefficient (Ibi). The diffuse color value (RGB) for that vertex (V) is then modified according to the value of the modified specular reflection value (SRi) for the corresponding vertex. &lt;IMAGE&gt;</p>
