Simple silhouettes for complex surfaces

TL;DR: Inspired by the comic-book production pipeline, a method is proposed for integrating visual aspects of the sketching process into 3D sketch-based modeling systems and new methods are described for computing silhouettes, suggestive contours, surface stippling, and surfel-based visibility culling.

TL;DR: In this article, a method for determining a likelihood that a viewpoint undergoes movement from a first view region to a second view region is presented. But the method does not specify a motion path.

TL;DR: In this article, a computer-implemented method was proposed to determine a set of mesh polygons or fragments of the mesh polygon visible from a navigation cell using the determined one or more intersections of the at least one wedge with the contained meshes.

TL;DR: In this article, a first visibility event packet from a server is received via processing circuitry of a client device, and the first visibility packet includes information representing 3D surface elements of an environmental model that are occluded from a first viewcell and not occlated from a second viewcell, representing spatial regions of a specified navigational route within a real environment modeled by the environmental model.

TL;DR: An efficient, deterministic algorithm for finding silhouettes based on geometric duality, and an algorithm for segmenting the silhouette curves into smooth parts with constant visibility can be used to find all silhouettes in real time in software.

TL;DR: A paradigm for the display of technical illustrations in a dynamic environment is presented that includes all of the benefits of computer generated technical illustrations, such as a clearer picture of shape, structure, and material composition than traditional computer graphics methods.

TL;DR: An algorithm for enhancing edges of real-time non-photorealistic renderings is proposed, based on the edge map, a 2D texture that encodes visually important edges of 3D scene objects, and includes silhouette edges, border edges, and crease edges.

TL;DR: Most applications of interest exhibit coherence in silhouettes between successive computations as viewpoints change slowly, and the video describes a technique for efficient tracking of perspective-accurate silhouettes by reducing the problem to point location queries.
