Summary
Function: rotation rLin( rotation x, rotation y, float t );
Interpolates between two rotation values in a linear fashion.
Returns a rotation
| • rotation | x | |||
| • rotation | y | |||
| • float | t |
Specification
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);
}
// Released into public domain. By Nexii Malthus.
Examples
rotation x = llEuler2Rot(<0,0,30*DEG_TO_RAD>);
rotation y = llEuler2Rot(<0,0,90*DEG_TO_RAD>);
rotation z = rLin(x, y, 0.5); // z equivalent to euler rotation of 60 degrees on Z axis
llOwnerSay((string)(llRot2Euler(z)*RAD_TO_DEG)); // <0.00000, 0.00000, 60.00001>
