rotaion about 3 axis

Is it possible to rotate about all three axis simultaneously or is it necessary to do three separate rotations?

I ask because this...

llRezObject( name, pos, ZERO_VECTOR, llEuler2Rot( <rx,ry,rz>, 0);

...gives nonsensical results, while this...

llRezObject( name, pos, ZERO_VECTOR, llEuler2Rot( <rx,0,0> * llEuler2Rot( <0,ry,0> * llEuler2Rot( <0,0,rz>, 0);

...works sometimes.

All the examples in the wiki work on one axis at a time. Is that because it's not possible to do otherwise?

rotations work in radians, not degress.. try this

vector MyVector = <1,2,3>;
MyVector *= DEG_TO_RAD;
rotation MyRotation = llEuler2Rot(MyVector);
llSetRot (MyRotation);

that' should solve your 'nonsensical' rotations

It doesn't. My calculations are in radians, not degrees.

By nonsensical I mean that the z-axis rotation seems to be calculated based on local coordinates, whereas x & y are global. That is, it looks like the rezzed object was rotated about global x and y, and then around its own local z axis. Unless I do each degree of freedom separately. My source object is aligned to the grid such that its local and global coordinate systems are aligned, so multiplying by llGetRot has no effect.

I think maybe the problem is in thinking that a Euler rotation is a simple 3-axis rotation as in Pitch/Roll/Yaw. But it is not. I would suggest that the mathematics wiki on Euler rotations be consulted as they have a great little graphical representation of a full Euler rotation and formulae for the conversion to/from quaternians.

Might help a little I hope.

If eulers in SL really are eulers, then both the LL and rpgstats wikis are wrong. Will consider this next time I do battle with rotations. Thanks, Lordly.
