Directional tubular surfaces

Abstract: In this paper, we introduce a new version of tubular surfaces. We first define a new adapted frame along a space curve, and denote this the q-frame. We then reveal the relationship between the Frenet frame and the q-frame. We give a parametric representation of a directional tubular surface using the q-frame. Finally, some comparative examples are shown to confirm the effectiveness of the proposed method.Mathematics Subject Classification: 53A04, 53A05

“…In this paper, we give another approach to evolutions of the ruled surfaces depend on a timelike space curve by q-frame used in [7,8,10,14]. Using q-frame, we present two sets of quasi frame equations with respect to arc-length s and time t .…”
