概要	Recent works in Non-Photorealistic Rendering (NPR) are capable of stylizing global appearance to fit shading designs by artists. Meanwhile, local appearance control is still required for the artists to depict geometric and emotional features. We propose a simple region control algorithm for an existing light-based texture projection technique. Since the shading effects of the texture projection cannot be overlayed, we consider to deform the original projection result by modifying texture coordinates. To enable artists to use familiar interface, we incorporate multiple lighting effects and painting control with the original light-based texture projection process. Our shading pipeline is implemented on GPU, which enables a real-time preview for the shading design at interactive rates. We also conducted user studies to evaluate the usability of our system.
