Hello. I have to rotate an object from <0,315,270> to <0,315,90> and back again. I used this to calc rotation:
vector eul = <0,0,180>; //180 degrees around the z-axis, in Euler form
eul *= DEG_TO_RAD; //convert to radians
rotation quat = llEuler2Rot(eul); //convert to quaternion
Result is <0.0, 0.0, 1.0, -0.0> But when I use this rotation (llSetRot=llGetRot()+quat) I get a very different rotation. What's wrong with my logic?? |
