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.
}
}</lsl>
