In computer graphics, a means of rendering a single three-dimensional object from multiple two-dimensional objects. There are two elements to this type of rendering: a "backbone", or a path along which the 3D object is to be created, and the 2D objects that form the outline of the rendered object. The 2D outlines are plotted along the path, the spaces betweeen them filled in with solid objects based on the 2D objects.
