In computer graphics, it is not always guaranteed to generate user-desired shading effects by physically correct shading algorithms, due to the high computational cost and laborious work for parameter tuning. On the other hand, environmental map is a popular technique to create realistic shading images with low computational cost. Therefore, many methods have been proposed for editing shading effects obtained by environmental map. Since the methods edits the environmental map that represents only lights locating infinitely far away, these cannot edit local lighting effects, e.g., of spotlights. In this chapter, we propose an intuitive system that allows the user to produce the desired shading effects. Our system allows the user to specify desired-intensities at arbitrary positions on surfaces of objects, and design both local and global shading effects intuitively.
