Item GPU Texture Level of Abstraction in 3D Scenes(The Eurographics Association, 2012) Suarez, Jordane; Belhadj, Farès; Boyer, Vincent; Andrea Fusiello and Michael WimmerWe present a method to dynamically control the texture level of abstraction in 3D scene. Level of abstraction consists in visualizing the necessary and sufficient information in an image. Texture generation is generally realized by a designer in a high resolutions with a low level of abstraction. Our model provides automatically texture level of abstraction through offline and online segmentation and lets the designer define the number of colors in the object texture.Item Consistent Media Model for Real-Time Scene Rendering(The Eurographics Association, 2012) Belhadj, Farès; Suarez, Jordane; Boyer, Vincent; Andrea Fusiello and Michael WimmerWe present a consistent model for artistic media reproduction in 3D scene renderings and animations. Artistic media reproduction can be defined as a media model (such as brush, pencil, ink) and a support (such as canvas and papers). We create a surface grain according to the object geometry and apply it as additional material properties. Furthermore, we propose to use the abstraction of obtained results as an entry of a fractal surface reconstruction process that provides additional effects of traditional media such as brush stroke effects. Our model is fully implemented on GPU and the rendering process is strongly real-time.
