Multiresolution control of curves and surfaces with a self-similar model
Résumé
This paper presents two self-similar models that allow the control of curves and
surfaces. The first model is based on IFS (Iterated Function Systems) theory and
the second on subdivision curve and surface theory. Both of these methods employ
the detail concept as in the wavelet transform and allow the multiresolution control
of objects with control points at any resolution level.
In the first model, the detail is inserted independently of control points, requiring
it to be rotated when applying deformations. On the contrary, the second
method describes details relative to control points, allowing free control point deformations.
Modelling examples of curves and surfaces are presented, showing manipulation
facilities of the models.
