Multi-Scale Capture of Facial Geometry and Motion
(Association for Computing Machinery, 2007)
We present a novel multi-scale representation and acquisition method for the animation of high-resolution facial geometry and wrinkles. We first acquire a static scan of the face including reflectance data at the highest ...
Exploring Defocus Matting: Nonparametric Acceleration, Super-Resolution, and Off-Center Matting
(Institute of Electrical and Electronics Engineers, 2007)
Defocus matting is a fully automatic and passive method for pulling mattes from video captured with coaxial cameras that have different depths of field and planes of focus. Nonparametric sampling can accelerate the ...
Inverse Shade Trees for Non-Parametric Material Representation and Editing
(Association for Computing Machinery, 2006)
Recent progress in the measurement of surface reflectance has created a demand for non-parametric appearance representations that are accurate, compact, and easy to use for rendering. Another crucial goal, which has so far ...
Abstract Shade Trees
(Association for Computing Machinery, 2006)
As GPU-powered special effects become more sophisticated, it becomes harder to create and manage effect interaction using the fairly primitive shading languages. This difficulty also introduces a workflow problem: artists ...
Rendering Deformable Surface Reflectance Fields
(Institute of Electrical and Electronics Engineers, 2005)
Animation of photorealistic computer graphics models is an important goal for many applications. Image-based modeling has emerged as a promising approach to capture and visualize real-world objects. Animating image-based ...
Fast Re-Rendering of Volume and Surface Graphics by Depth, Color, and Opacity Buffering
(Elsevier, 2000)
A method for quickly re-rendering volume data consisting of several distinct materials and intermixed with moving geometry is presented. The technique works by storing depth, color and opacity information, to a given ...
A Parallel Pipeline Convolution for Perspective Projection in Real-Time Volume Rendering
(Dō Gakkai, 2000)
This paper describes a convolution with a systolic array structure for perspective projection in real-time volume graphics based on the shear-warp method. In the original method, the further the ray proceeds, the more ...
A Data-Driven Reflectance Model
(Association for Computing Machinery, 2003)
We present a generative model for isotropic bidirectional reflectance distribution functions (BRDFs) based on acquired reflectance data. Instead of using analytical reflectance models, we represent each BRDF as a dense set ...
Opacity Light Fields: Interactive Rendering of Surface Light Fields with View-Dependent Opacity
(Association for Computing Machinery, 2003)
We present new hardware-accelerated techniques for rendering surface light fields with opacity hulls that allow for interactive visualization of objects that have complex reflectance properties and elaborate geometrical ...
Acquisition and Rendering of Transparent and Refractive Objects
(Association for Computing Machinery, 2002)
This paper introduces a new image-based approach to capturing and modeling highly specular, transparent, or translucent objects. We have built a system for automatically acquiring high quality graphical models of objects ...
