“…The framework extends our earlier work on distributed virtual environment [1], [2] to support collaborative sculpting. To do this, we adapt our real-time techniques for rendering deformable NURBS surfaces [16], [17] and for virtual sculpting [18] into the new framework. We have introduced the NURBS streams for transmitting deforming objects through the network.…”

“…In order for the user to be able to sculpt the object in an intuitive manner, we adapt our virtual sculpting technique here [18] to allow direct object modification with the user's own hands. Each user participate in the collaborative sculpting will wear one or a pair of CyberGloves.…”

It encourages international collaboration at a minimal cost. However, in order for the system to be useful, two factors need to be addressed: intuitiveness and real-time interaction. Although a lot of effort has been put into developing virtual sculpting environments, only limited work addresses collaborative virtual sculpting. This is because in order to support real-time collaborative virtual sculpting, many challenging issues need to be addressed. In this paper, we propose a collaborative virtual sculpting framework, called VSculpt. Through adapting some techniques we developed earlier and integrating them with some techniques developed here, the proposed framework provides a real-time intuitive environment for collaborative design. In particular, it addresses issues on efficient rendering and transmission of deformable objects, intuitive object deformation using the CyberGlove and concurrent object deformation by multiple clients. We demonstrate and evaluate the performance of the proposed framework through a number of experiments.

“…Most existing methods manipulate shape on triangle meshes or parametric surfaces by predicting displacement for influenced mesh vertices or parametric subdomains. Fowler [1992] and Wong et al [2000] proposed a method for direct manipulation of the surface using a B-spline tensor product representation. Terzopoulos and Qin [1994] developed a dynamic generalization of the NURBS model for physically intuitive surface manipulation.…”
