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
<lsl>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.</lsl>
Examples
<lsl> rotation x = llRot2Euler(<0,0,30*DEG_TO_RAD>); rotation y = llRot2Euler(<0,0,90*DEG_TO_RAD>);
rotation z = rLin(x, y, 0.5); // z equivalent to euler rotation of 60 degrees on Z axis</lsl>
