how can I rotate a vector using a quaternion to get new vector?

[Anonymous]

Hello,

How do I rotate this vector x= 1262.443471 y= -1548.873281 z= 2729.985187

using quaterion

myquaternion = (quat -0.29571 -0.11778 -0.41487 0.85239)

to get a new vector in maxscript?

thank you

Multiply the vector by that quaternion.
