SUMMARY:S3 Imagery: Specular Shading from Scratch-Anisotropy
DESCRIPTION:Pengfei Shen, Feifan Qu, and Li Liao (University of Hong Kong)
 ; Ruizhen Hu (Shenzhen University (SZU)); and Yifan Peng (University of Ho
 ng Kong)\n\nScratch-represented 3D visual arts can create compelling visua
 l effects by manipulating light reflections across surfaces. Established w
 orks, such as those involving scratch holograms, have realized impressive 
 multi-view imagery effects of reflection arts. However, creating a continu
 ous view of 3D virtual objects with shading effects, especially view-depen
 dent shading remains a challenge. Yet, most reported works are demonstrate
 d on planar surfaces, leaving exploring the potential benefits of leveragi
 ng curved surfaces for diverse imagery scenarios an interesting research a
 venue. This work explores the continuous view-dependent imagery with rich 
 shading\neffects via scratch-based reflection, whose design space has the 
 potential to be extended to arbitrary curved surfaces. This is achieved by
  solving the ordinary differential equations under constraints calculated 
 from established bidirectional reflectance distribution function models to
  optimize scratch distribution on substrate surfaces. Importantly, we crea
 te real-world examples\nby manufacturing optimized reflectors using off-th
 e-shelf carving machines, delivering state-of-the-art specular view-depend
 ent imagery that features continuous and realistic shading effects on both
  planar and curved surfaces.\n\nRegistration Category: Full Access, Full A
