Recent extensions to the standard difference-of-Gaussians (DoG) edge detection operator have rendered it less susceptible to noise and increased its aesthetic appeal. Despite these advances, the technical subtleties and stylistic potential of the DoG operator are often overlooked. This paper offers a detailed review of the DoG operator and its extensions, highlighting useful relationships to other image processing techniques. It also presents many new results spanning a variety of styles, including pencil-shading, pastel, hatching, and woodcut. Additionally, we demonstrate a range of subtle artistic effects, such as ghosting, speed-lines, negative edges, indication, and abstraction, all of which are obtained using an extended DoG formulation, or slight modifications thereof. In all cases, the visual quality achieved by the extended DoG operator is comparable to or better than those of systems dedicated to a single style.

“…They used the SPH approximation method to determine the density of the fluid on the surface of the mesh and placed hatching textures that follow the directions of the fluid. Praun et al, [7] developed a tonal art map for hatching a 3D mesh in real time. They overlapped a simple hatching stroke with various densities to create a series of textures and applied these to a mesh.…”

“…Artists often convey various tones with strokes of different densities or by varying the pressure of the pencil point. Unlike most of the NPR techniques which use strokes or precomputed textures to display different tones [24,19,12], we use a point-based shading algorithm to avoid sending the triangular meshes over the network.…”

We present a non-photorealistic rendering technique for interactive exploration of isosurfaces generated from remote volumetric data. Instead of relying on the conventional smooth shading technique to render the isosurfaces, a point-based technique is used to represent and render the isosurfaces in a remote client-server environment. The non-photorealistic nature of the proposed rendering method enables the server to transmit only the essential surface features, which substantially reduces the network traffic. The algorithm also utilizes frame coherence and efficiently encodes the isosurface configuration inside each voxel cell to further minimize the network overhead. Finally, our algorithm can adjust the point distributions using different illumination settings to adapt to different network speeds.
