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:
“Commerce is unexpectedly confident and serene, alert, adventurous, and unwearied. It is very natural in its methods withal, far more so than many fantastic enterprises and sentimental experiments, and hence its singular success.”
—Henry David Thoreau (1817–1862)
