These models<br /> di er in their choice of potential functions but agree upon the use of underlying modelling primitives,<br /> namely, points. In this paper a method is described for modelling and rendering implicit surfaces built<br /> upon an expanded set of skeletal primitives: points, line segments, polygons, arcs and planes. An algo-<br /> rithm for ray-tracing the surfaces formed through convolution of any combination of these primitives<br /> is also presented. The algorithm employs analytical methods only, which makes it computationally<br /> e ective.<br /> <br /> == Extended Abstract ==<br /> <br /> == Bibtex == <br /> <br /> == Used References ==<br /> 1.
