Photon Tracing - Shading Methods

Shading Methods

Because the rendering method differs from both ray tracing and scan line rendering, photon tracing needs its own set of shaders.

  • Surface shader - dictates how the photon rays reflect or refract.
  • Absorption shader - tells the ray if the photon should be absorbed or not.
  • Emission shader - when called it emits a photon ray

Famous quotes containing the word methods:

    How can you tell if you discipline effectively? Ask yourself if your disciplinary methods generally produce lasting results in a manner you find acceptable. Whether your philosophy is democratic or autocratic, whatever techniques you use—reasoning, a “star” chart, time-outs, or spanking—if it doesn’t work, it’s not effective.
    Stanley Turecki (20th century)
