Summary
Function: vector vCub( vector a, vector b, vector c, vector d, float t );
Cubic interpolation between four vectors.
Returns a vector
| • vector | a | |||
| • vector | b | |||
| • vector | c | |||
| • vector | d | |||
| • float | t |
Specification
<lsl>vector vCub(vector a, vector b, vector c, vector d, float t) {
float P = (d-c)-(a-b); return P*llPow(t,3) + ((a-b)-P)*llPow(t,2) + (c-a)*t + b;
