Summary
Function: vector llRot2Up( rotation q );20 | Function ID |
0.0 | Forced Delay |
10.0 | Energy |
Computes the orientation of the local z-axis relative to the earth.
Returns a vector that is the up vector defined by q, i.e. a unit vector pointing in the positive Z direction
• rotation | q |
Can be useful to identify the orientation of the local horizontal-plane of the prim, since it's z-axis is always perpendicular to this local horizontal plane.
Specification
Mathematically equivalent to: <lsl>ret = llVecNorm(<0., 0., 1.> * q);</lsl> If q is known to be a unit quaternion then it can be simplified as: <lsl>ret = <0., 0., 1.> * q;</lsl>
