Remote rendering using vtk and vic

摘要

This paper presents a remote rendering application that involves the extension ofthe Visualization Toolkit (vtk) and the Video Conferencing Tool (vie) for use in remote rendering complete with interaction from the remote site using the vie user interface. Vtk is an open source C++ library, with Tel, Python, and Java bindings for computer graphics, image processing, and visualization (3). Vtk provides a higher level of support, beyond the traditional low-level libraries, for creating visualization applications. Vtk includes algorithms to support the visualization of scalars, vectors, and tensors. Vic is a flexible tool built by Lawrence Berkeley National Laboratory for real-time video conferencing over the Internet (2). Vie's user interface is built as Tcl/Tk script embedded in the applications. This allows developers to prototype changes to the interface in a simple and straightforward manner.
