The unknown vector constants K

, as well as the parameter ,
have to be determined. To do this, we initially impose four conditions on
Equation (11.1):
1. The spline passes through the point P
i
at the start of the curve. At this
point, = 0.
2. The spline passes through the point P
i+1
at the end of the curve. At
this point, = 1
3. The derivative of the spline at P
i
is given. That is P
i
.
4. The derivative of the spline at P
i+1
is given. That is P
i+1
.
The parameter
in the equations for the spline is related to the distance
traveled ...
