示例1: NewTwist
func NewTwist(w, q vec.Vectorer) Twister {
t := new(twist)
t.w = w // set the axis of motion of joint
t.q = q // set the position a point on the axis of joint
t.v = vec.Zeros(AxisLength)
t.v.Cross(q, w) // qxw
t.t = mesh.Gen(nil, TwistLength, 1)
tvec := t.t.Vec().Slice()
copy(tvec[3:], w.Slice())
copy(tvec[:3], t.v.Slice())
return t
