The idea is that the macro fill in the unspecified T values for you using
linear interpolation.
The macro will convert this:
array[7*2] {
0.0*y, <0,1,2>,
x, <1,5,0>,
x, <4,1,0>,
0.9*y, <0,2,1>,
1.0*y, <0,0,1>,
x, <6,5,4>,
2.0*y, <4,3,2>,
}
Into this:
0.0, <0,1,2>,
0.3, <1,5,0>,
0.6, <4,1,0>,
0.9, <0,2,1>,
1.0, <0,0,1>,
1.5, <6,5,4>,
2.0, <4,3,2>,
You're only required to specify the first and last T value; the rest are
optional. In some cases that can make it easier to work with splines.
