Classical Radiosity Method
•Divide
surfaces into patches
•Model
light transfer between patches as system of linear equations
•Important
assumptions (so far):
–Reflection
and emission are diffuse
–No
participating media (no fog)
–No
transmission (only opaque surfaces)
–Radiosity
is constant across each patch
–Solve
for R, G, B separately
