At every point in a 3D scene, light is coming in and light
is going out. Each point of space is a little computer that takes
as input the incoming spectrum from a set of spherical directions
and delivers as output another spherical distribution of spectral
intensities.
This course is concerned with algorithms for creating
realistic 3D images by simulating the transport of light.
Topics include ray-casting, sampling,
reflectance, and transmittance.
