Texture for Appearance Models in Computer Vision and Graphics
Appearance modeling is fundamental to the goals of computer vision and computer graphics. Traditionally, appearance was modeled with simple shading models (e.g. Lambertian or specular) applied to known or estimated surface geometry. However, real world surfaces such as hair, skin, fur, gravel, scratched or weathered surfaces, are difficult to model with this approach for a variety of reasons. I...
متن کاملModern Texture Mapping in Computer Graphics
Textures have a variety of applications in computer graphics. While the original idea of texture mapping was just to cover the surface of an object with an image to avoid having to model every detail geometrically, in time a lot of other uses have been proposed. In this paper, the most important applications of texture mapping (except the original approach) will be explained.
متن کاملSparse Reconstruction of Visual Appearance for Computer Graphics and Vision
A broad range of problems in computer graphics rendering, appearance acquisition for graphics and vision, and imaging, involve sampling, reconstruction, and integration of high-dimensional (4D-8D) signals. For example, precomputationbased real-time rendering of glossy materials and intricate lighting effects like caustics, can involve (pre)-computing the response of the scene to different light...
متن کاملApproximating the Appearance of Human Skin in Computer Graphics
The simulation of realistic lighting and shading for the reproduction of human skin in computer graphics is a subject of great depth. This paper deals with a method for implementing an approximation of the appearance of human skin in a RenderMan shading network, and using Pixar’s ‘prman’ scan-line native renderer.
متن کاملA Generalized Surface Appearance Representation for Computer Graphics
(Under the direction of Anselmo Lastra) For image synthesis in computer graphics, two major approaches for representing a surface's appearance are texture mapping, which provides spatial detail, such as wallpaper, or wood grain; and the 4D bi-directional reflectance distribution function (BRDF) which provides angular detail, telling how light reflects off surfaces. I combine these two modes of ...
