Undoing Homogenization<br />
we add<br />
! a i = 1 ! b i = 1<br />
i<br />
i<br />
now its solvable and the solution is:<br />
h 2 h 3 b 1<br />
a 1 =<br />
h 2 h 3 b 1 + h 1 h 3 b 2 + h 1 h 2 b 3<br />
similar formulas exist for<br />
and<br />

Bump/Displacement Mapping<br />
Texture mapping<br />
changes a surface’s<br />
reflectance, but<br />
that can’t give us a<br />
realistic orange<br />
For this we can<br />
use bump or<br />
displacement<br />
mapping<br />
