AxisAngle2Rot

llAxisAngle2Rot

Summary

Function: rotation llAxisAngle2Rot( vector axis, float angle );

0.0	Forced Delay
10.0	Energy

Returns a rotation that is a generated angle about axis

• vector	axis
• float	angle	–	expressed in radians.

axis need not be normalized, only the direction is important.

Examples

<lsl>default {

   state_entry()
   {
       vector axis = <0.0, 0.0, 1.0>;
       float angle = 90.0 * DEG_TO_RAD;
       rotation rot = llAxisAngle2Rot(axis, angle);
       vector euler = llRot2Euler(rot) * RAD_TO_DEG;

       llOwnerSay((string) euler);
       //Says <0.0, 0.0, 90.0> since it is rotating 90 degrees on the Z axis caused by the 1.0 placed in the Z vector spot. 
   }

Deep Notes

<lsl>rotation llAxisAngle2Rot( vector axis, float angle ) {

   axis = llVecNorm( axis ) * llSin( angle/2 );
   return <axis.x, axis.y, axis.z, llCos( angle/2 )>;

}</lsl>
