Barycentric Coordinates<br />
X<br />
can be expressed as<br />
!P 1 + "P 2 + #P 3<br />
where<br />
! + " + # = 1<br />
or, alternatively as<br />
X<br />
P 1<br />

We can use barycentric<br />
coordinates to interpolate<br />
any quantity (color,<br />
texture coordinates, etc)<br />
stored at vertices, not just<br />
positions.<br />
