Summary
Function: rotation rCub( rotation a, rotation b, rotation c, rotation d, float t );
Spherical-Cubic interpolation between four rotations.
Returns a rotation
| • rotation | a | – | Start | |
| • rotation | b | – | End | |
| • rotation | c | – | Affects path curve | |
| • rotation | d | – | Affects path curve | |
| • float | t |
Specification
rotation rCub(rotation a, rotation b, rotation c, rotation d, float t){
return rLin( rLin(a,b,t), rLin(c,d,t), 2*t*(1-t) );
}
rotation rLin(rotation x, rotation y, float t) {
float ang = llAngleBetween(x, y);
if(ang > PI) ang -= TWO_PI;
return x * llAxisAngle2Rot(llRot2Axis(y/x)*x, ang*t);
