Rendering

(Information Science Master) Lecture on Computer Graphics by Professor Kenji Igarashi.

• Takes a 3D representation (such as a 3D model) as input and outputs a realistic image.

• Distribution functions: Simulates reflection and other phenomena.

  • Takes incoming light as input and outputs outgoing light.

• If we calculate the movement of all light using distribution functions, we can obtain a realistic image.

  • However, the computational complexity is high.
  • So, we strive to find simpler methods (sampling).
    • Metropolis Light Transport
    • Precomputed Radiance Transfer (real-time rendering)
      • Rendering mainly takes time for integration, so we speed it up through precomputation (spherical harmonics).
