Path drawing for 3D walkthrough

Abstract: This paper presents an interaction technique for walkthrough in virtual 3D spaces, where the user draws the intended path directly on the scene, and the avatar automatically moves along the path. The system calculates the path by projecting the stroke drawn on the screen to the walking surface in the 3D world. Using this technique, the user can specify not only the goal position, but also the route to take and the camera direction at the goal with a single stroke. A prototype system is tested using a displayin… Show more

“…In (Igarashi et al, 1998) the 2D line is specified using the mouse. The Marking Points metaphor requires the placement of markers along a path of the VE: the system is responsible for creating a continuous path through this sequence of points.…”

“…Recognizing the limitations of these existing tools, researchers have been working on tools for sketching and refining curves in a more direct manner [2,4,5,8,9,11,[15][16][17]. While sketching is a very useful paradigm for creating and refining curves, another paradigm that has not received as much attention is the use of high degree-of-freedom input devices to directly manipulate virtual curves.…”
