This paper proposes a new sketch method for plant modeling, which combines parametric L-System, and Ball B-Spline Curves, which are objects derived from a parametric solid representation method. By taking the automatic property of L-system and the freedom property of sketching, the users can create realistic plants conveniently according to their willing.
This paper proposes a parametric solid representation of freeform tubular objects - Ball B-Spline Curves (BBSCs), which are skeleton based parametric solid model. Their fundamental properties, algorithms and modeling methods are investigated. BBSC directly defines objects in B-Spline function form (not a procedure method, like sweeping), that uses control ball instead of control point in B-Spline...
In this paper, we present an interactive system for quickly and easily modeling 3D trees with ball B- spline curves(BBSCs). As BBSCs are flexible for modifying, deforming and editing, these methods provide intuitive interaction and more freedom for users to model trees interactively. These interactive methods can also be used in conjunction with other methods like generating tree models through L-...
