Sculpting method

The sense of feeling can effectively be used to enforce virtual artistic activities like virtual sculpting or modeling. In this paper, we describe how a virtual sculpture system has been extended with haptical feedback. In practice, we use the scalar field defining the implicit surface being modeled to efficiently compute several type of force feedback. We present a method for combining these forces differently depending whether the user is just touching his artwork or editing it by adding virtual matter.

Apoptosis in the developing nervous system results in naturally occurring cell death (NOCD), a necessary and desirable process. NOCD effectively eliminates neurons that have made faulty synapses or have not reached appropriate targets. 1 In the rest of the organism, apoptosis is essential for organogenesis, sculpts digits and extremities, and plays a role in determining polarity of structures by contributing to directional growth of cell populations. 2 Failure of carefully orchestrated and effective apoptosis in the developing fetus can have serious and long-lasting effects in the adult.
