Exploring entities in text with descriptive non-photorealistic rendering
… to text visualization called descriptive non-photorealistic rendering which exploits the inherent spatial and abstract dimensions in text documents to integrate 3D non-photorealistic rendering with information visualization. The visualization encodes text data onto 3D models, emphasizing …

Design and implementation of non-photorealistic rendering techniques for 3D geospatial data
… detail to provide realistic imagery. However, a photorealistic rendering does not automatically lead to high image quality, with respect to an effective information transfer, which requires important or prioritized information to be interactively highlighted in a context-dependent manner. …

The Comic Artist’s Tools Suite: Centralized and Intuitive Non-Photorealistic Computer Graphics Renderings
… in Computer Generated Imagery (CGI) software and Non-Photorealistic Rendering (NPR) techniques, modern comic artists have reaped the benefits of technology-aided workflows by creating 3D CGI environments for their comic backgrounds. However, while several NPR techniques exist, there remains a high …

Image and Color Stylization through Region-based Abstraction
In Non-Photorealistic Rendering (NPR), abstraction methods simplify images. The NPR techniques produce stylized imagery by emphasizing the main structures through stroke elements, colors and removing unessential image information. However, the difficulty of abstraction lies in deciding what is …

Videorealistic facial animation for speech-based interfaces
… research with videorealistic animations, both photorealistic and non-photorealistic, has reached the point where there is little discernible difference between the mouth movements of videorealistic animations and the mouth movements of actual humans. Because of the minute differences between …

Afterimage Toon Blur : procedural generation of cartoon blur for 3D models in real time
… history of 3D models to, in real time, construct non-photorealistic motion blur effects in the vein of 2D traditional animation. With these procedural techniques, designers can maximize the convenience of 3D models while still retaining an aesthetic normally constrained to 2D animation.

Stylized Hatching for 3D Animation
Much research has been done in creating non-photorealistic renderings of objects that mimic the look of hand-made drawings by traditional artists. This thesis extends work in this area by presenting an NPR hatching method that can be applied to 3D animated films to help them feel more hand drawn. …

Apparent ridges for line drawing
Non-photorealistic line drawing depicts 3D shapes through the rendering of feature lines. A number of characterizations of relevant lines have been proposed but none of these definitions alone seem to capture all visually-relevant lines. We introduce a new definition of feature lines based on two …

Real-Time Stylized Rendering for Large-Scale 3D Scenes
… for stylized rendering tools. Stylized, or non-photorealistic rendering (NPR), applications generally sacrifice physical accuracy for artistic or functional visual output. Oftentimes, NPR applications focus on extracting specific features from a 3D environment and highlighting them in a …

A projective approach to computer-aided drawing
… shading of primitives using either realistic or non-photorealistic styles. My system supports drawing and shading of extrusion surfaces with automatic hidden surface removal and emphasized silhouettes. Casting shadows from an infinite light source is also possible with minimal user intervention. …

Structure adaptive stylization of images and video
… create realistic synthetic imagery. By contrast, non-photorealistic computer graphics, established as its own branch of computer graphics in the early 1990s, is mainly motivated by concepts and principles found in traditional art forms, such as painting, illustration, and graphic design, and it …

Colour videos with depth : acquisition, processing and evaluation
… results. In addition, I demonstrate enhanced non-photorealistic rendering techniques and the ability to synthesise stereoscopic videos, which allows these effects to be applied stereoscopically. These stereoscopic renderings inspired me to study stereoscopic viewing discomfort. The result of …

Emotive implications of rendering in conceptual design
… styles that cover a spectrum of existing photorealistic rendering (PR) and non-photorealistic rendering (NPR) styles in conceptual design. The study involved a sample of sixty-one respondents, which included academics, fourth year and fifth year undergraduate and postgraduate students. The …

Marco de Trabajo de Rendering no Fotorrealista.
… Fotorrealista, o NPR por sus siglas en inglés (Non Photorealistic Rendering). El NPR integra conceptos de Computación Gráfica y de Geometría Diferencial, y puede aplicarse en visualización científica e ilustración técnica, con el fin de destacar áreas o contornos de los objetos que son de …

Accurate and discernible photocollages
There currently exist several techniques for selecting and combining images from a digital image library into a single image so that the result meets certain prespecified visual criteria. Image mosaic methods, first explored by Connors and Trivedi[18], arrange library images according to some …

Image Vectorization
We present a new technique for creating an editable vector graphic from an object in a raster image. Object selection is performed interactively in subsecond time by calling graph cut with each mouse movement. A renderable mesh is then computed automatically for the selected object and each of its …

Machine Learning Algorithms for Geometry Processing by Example
This thesis proposes machine learning algorithms for processing geometry by example. Each algorithm takes as input a collection of shapes along with exemplar values of target properties related to shape processing tasks. The goal of the algorithms is to output a function that maps from the shape …
