Summary
Function: vector llRot2Fwd( rotation q );18 | Function ID |
0.0 | Forced Delay |
10.0 | Energy |
Computes the orientation of the local x-axis relative to the earth.
Returns a vector that is the forward vector defined by q, i.e. a unit vector pointing in the local positive X direction.
• rotation | q |
Can be useful to identify the orientation of the local frontal-plane of the prim, since it's x-axis is always perpendicular to this local frontal plane.
Specification
Mathematically equivalent to: <lsl>ret = llVecNorm(<1., 0., 0.> * q);</lsl> If q is known to be a unit quaternion then it can be simplified as: <lsl>ret = <1., 0., 0.> * q;</lsl>
