    • Neural BRDF Representation and Importance Sampling 

      Sztrajman, Alejandro; Rainer, Gilles; Ritschel, Tobias; Weyrich, Tim (© 2021 Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd, 2021)
      Controlled capture of real‐world material appearance yields tabulated sets of highly realistic reflectance data. In practice, however, its high memory footprint requires compressing into a representation that can be used ...

    • Neural Precomputed Radiance Transfer 

      Rainer, Gilles; Bousseau, Adrien; Ritschel, Tobias; Drettakis, George (The Eurographics Association and John Wiley & Sons Ltd., 2022)
      Recent advances in neural rendering indicate immense promise for architectures that learn light transport, allowing efficient rendering of global illumination effects once such methods are trained. The training phase of ...

    • Neural Shading Fields for Efficient Facial Inverse Rendering 

      Rainer, Gilles; Bridgeman, Lewis; Ghosh, Abhijeet (The Eurographics Association and John Wiley & Sons Ltd., 2023)
      Given a set of unstructured photographs of a subject under unknown lighting, 3D geometry reconstruction is relatively easy, but reflectance estimation remains a challenge. This is because it requires disentangling lighting ...

    • Unified Neural Encoding of BTFs 

      Rainer, Gilles; Ghosh, Abhijeet; Jakob, Wenzel; Weyrich, Tim (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      Realistic rendering using discrete reflectance measurements is challenging, because arbitrary directions on the light and view hemispheres are queried at render time, incurring large memory requirements and the need for ...
