A Natural Image Pointillism with Controlled Ellipse Dots

This paper presents an image-based artistic rendering algorithm for the automatic Pointillism style. At first, ellipse dot locations are randomly generated based on a source image; then dot orientations are precalculated with help of a direction map; a saliency map of the source image decides long and short radius of the ellipse dot. At last, the rendering runs layer-by-layer from large size dots to small size dots so as to reserve the detailed parts of the image. Although only ellipse dot shape is adopted, the final Pointillism style performs well because of variable characteristics of the dot

Real-Time Stylized Rendering for Large-Scale 3D Scenes

While modern digital entertainment has seen a major shift toward photorealism in animation, there is still significant demand 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 unique manner. One application of interest involves recreating 2D hand-drawn art styles in a 3D-modeled environment. This task poses challenges in the form of spatial coherence, feature extraction, and stroke line rendering. Previous research on this topic has also struggled to overcome specific performance bottlenecks, which have limited use of this technology in real-time applications. Specifically, many stylized rendering techniques have difficulty operating on large-scale scenes, such as open-world terrain environments. In this paper, we describe various novel rendering techniques for mimicking hand-drawn art styles in a large-scale 3D environment, including modifications to existing methods for stroke rendering and hatch-line texturing. Our system focuses on providing various complex styles while maintaining real-time performance, to maximize user-interactability. Our results demonstrate improved performance over existing real-time methods, and offer a few unique style options for users, though the system still suffers from some visual inconsistencies

No foto realismo con esgrafiado

Cuando se crea una imagen para comunicar una idea, se está utilizando un lenguaje visual. Podemos “visualizar” nuestro pensamiento de la misma manera en que lo verbalizamos. Un diagrama, un mapa, una pintura son ejemplos del uso del lenguaje visual. Sus unidades estructurales son la línea, la forma, el color, el movimiento, la textura, entre otros. El arte pictórico ha demostrado que el uso de dichas unidades permite transmitir significados sin utilizar palabras. El área de No Foto realismo estudia la generación de imágenes que permitan la transmisión de mensajes visuales con expresión y estilo. En este trabajo, se presenta un prototipo de herramienta para la simulación de la técnica artística del Esgrafiado. La misma reúne elementos provenientes del área de la computación gráfica, el procesamiento de imágenes, el arte y la psicología cognitiva experimental, intentando brindar un medio para el desarrollo de habilidades de comunicación visual en un usuario observador así como también lo habilita al uso de los conceptos con otras herramientas para propósitos específicos a ámbitos no artísticos.A visual language is used when creating an image to communicate a subject. We can visualize our thinking as we can verbalize it. A diagram, a map, a painting are different examples of our visual language use. Line, shape, color, movement, texture, among others are their structural units, and pictorial art have shown their power for communicating messages without words. The Non Foto realism area studies the use of expresion and style in the creation of images for communicating visual messages. At this work, we present a prototype tool for the simulation of the artistic technique called Esgrafiado. The technique gathers elements from computer graphics, image processing, art and and experimental cognitive psychology trying to give a means for the development of visual communication skills to a user-observer. The technique enables the given concepts could be applied by the user into non artistic fields with specific subjects tools.V Workshop de Computación Gráfica, Imágenes Y VisualizaciónRed de Universidades con Carreras en Informática (RedUNCI
