6 CONCLUSION AND FUTURE
WORK
In this paper, we present a physical-based deforma-
tion method. When working with our deformation
method, the designer does not need to manipulate
some non-intuitive mathematical shape parameters,
such as control points and control vectors. Instead,
he/she can work with the point constraints and
spline-based constraints, therefore designers can
easily and intuitively control the resultant shape.
The potential function is centered at the con-
straint and it symmetrically distributes the so-called
force energy. Compared with other deformation
methods, this approach has the following advantages:
intuition, locality and simplification since this
method combines shape creation and deformation.
Finally, it is possible to use various intensities and
smoothing functions to enrich the quality and accu-
racy of the deformation.
Although our method is intuitive and less compu-
tationally challenging for free form surface modeling
and styling, it still needs some time to create sophis-
ticated models; and there is a limitation in our de-
formation technique when we want to change the
topology of the model, such as creating a hole.
In the future work, we will further investigate in-
telligent operations for shape editing and multi-
surfaces modeling based on 3D sketching; such as
surface splitting and stitching. We also plan to im-
prove the connectivity and continuity between dif-
ferent surfaces based on declarative constraints.
