Matrix Radiosity Revisited
•Compute
all form factors Fi j
•Make
initial approximation to radiosity
–Emitting
elements Bi = Ei
–Other
elements Bi = 0
•Apply
equation to get next approximation
•Iterate
with new approximation
•Intuitively
–Gather
incoming light for each element i
–Base
new estimate on previous estimate
