Matrix in wrangle SOP

[mirHadi]

trying to shorten the code more and more.... like this:

matrix3 m = set(v@tangentv, v@tangentu ,@N);

float angle = @Time;

vector axis = @N;

 

rotate(m, angle, axis);

@orient = quaternion(m);

 

and even more shorter like:

 

float angle = @Time;

vector axis = @N;

@orient = quaternion(angle, axis);

 

 

this should work right?

but @orient strangely shifts when the geometry deforms.

don't know why!
