// |
|

// Def: let w[i] = (w[i](x), w[i](y), w[i](z)) be the direction and speed we have to be flying at Point P[i] |
|
| 36 |
// |
|
| 37 |
// time it takes to fly though one segment v[i] --> v[i+1] : 0.0 --> 1.0 |
|
| 38 |
// w[i] should be parallel to v[i+1] - v[i-1] (cyclic notation) |
|
| 39 |
// |w[i]| proportional to | P[i]-P[i+1] | |
|
| 40 |
// |
|
| 41 |
// Given that the flight route (X(t), Y(t), Z(t)) from P(i) to P(i+1) (0<=t<=1) has to satisfy |
|
| 42 |
// X(0) = P[i ](x), Y(0)=P[i ](y), Z(0)=P[i ](z), X'(0) = w[i ](x), Y'(0) = w[i ](y), Z'(0) = w[i ](z) |

// X(1) = P[i+1](x), Y(1)=P[i+1](y), Z(1)=P[i+1](z), X'(1) = w[i+1](x), Y'(1) = w[i+1](y), Z'(1) = w[i+1](z) |
|
| 44 |
// |
|
| 45 |
// we have the solution: X(t) = at^3 + bt^2 + ct + d where |
|

// a = 2*P[i](x) + w[i](x) - 2*P[i+1](x) + w[i+1](x) |
