The radiance estimate derived in the previous chapter allows us to begin rendering images. The first step is building a photon map using photon tracing as described in Chapter 5. This photon map can ...

The photon map is a representation (a map) of all the stored photons in the model. A fundamental aspect of the photon map is that it is decoupled from the geometry in the model. This means that we do ...

The detection of light at the single-photon level is important for tasks ranging from fluorescence imaging to quantum information processing, reports Neil Savage. High-sensitivity detectors that ...
