Real v.s. Rendered

  • A screenshot of Blender during the 3-D modeling process. (Zhang et al., 2016)
  • A screenshot of MaxwellRender during the rendering process. Here, a customised texture map is used to represent glittery material. (Zhang et al., 2016)
  • Real v.s. Rendered. (A) Photographed set in studio lighting. (B) Rendered image set in Debevec’s “Eucalyptus Grove” image-based lighting. (C) Rendered image set in Debevec’s “Grace Cathedral” image-based lighting. (Zhang et al., 2016)
  • The “bird” set rendered in the canonical material-lighting framework. (Zhang et al., 2019)
  • Three light maps vary in 15 orientations, and examples of the three shapes, rendered with the specular material and the Grace-new light map. (Zhang et al., 2020)
