Making Radiance and Irradiance Caching Practical: Adaptive Caching and Neighbor Clamping
(The Eurographics Association, 2006)
Radiance and irradiance caching are efficient global illumination algorithms based on interpolating indirect illumination from a sparse set of cached values. In this paper we propose an adaptive algorithm for guiding spatial ...
Sparse Lumigraph Relighting by Illumination and Reflectance Estimation from Multi-View Images
(The Eurographics Association, 2006)
We present a novel relighting approach that does not assume that the illumination is known or controllable. Instead, we estimate the illumination and texture from given multi-view images captured under a single illumination ...
Real-time Soft Shadow Mapping by Backprojection
(The Eurographics Association, 2006)
We present a new real-time soft shadow algorithm using a single shadow map per light source. Therefore, our algorithm is well suited to render both complex and dynamic scenes, and it handles all rasterizable geometries. ...
Feature-Aware Texturing
(The Eurographics Association, 2006)
We present a method for inhomogeneous 2D texture mapping guided by a feature mask, that preserves some regions of the image, such as foreground objects or other prominent parts. The method is able to arbitrarily warp a ...
Painting With Texture
(The Eurographics Association, 2006)
We present an interactive texture painting system that allows the user to author digital images by painting with a palette of input textures. At the core of our system is an interactive texture synthesis algorithm that ...
Surface Enhancement Using Real-time Photometric Stereo and Reflectance Transformation
(The Eurographics Association, 2006)
Photometric stereo recovers per-pixel estimates of surface orientation from images of a surface under varying lighting conditions. Transforming reflectance based on recovered normal directions is useful for enhancing the ...
A GPU-driven Algorithm for Accurate Interactive Reflections on Curved Objects
(The Eurographics Association, 2006)
We present a GPU-driven method for the fast computation of specular reflections on curved objects. For every reflector of the scene, our method computes a virtual object for every other object reflected in it. This virtual ...
Exploiting Temporal Coherence for Incremental All-Frequency Relighting
(The Eurographics Association, 2006)
Precomputed radiance transfer (PRT) enables all-frequency relighting with complex illumination, materials and shadows. To achieve real-time performance, PRT exploits angular coherence in the illumination, and spatial ...
An Efficient Multi-View Rasterization Architecture
(The Eurographics Association, 2006)
TV have been designed and built. However, these displays have received relatively little attention in the context of real-time computer graphics. We present a novel rasterization architecture that rasterizes each triangle ...
Tomographic Reconstruction of Transparent Objects
(The Eurographics Association, 2006)
The scanning of 3D geometry has become a popular way of capturing the shape of real-world objects. Transparent objects, however, pose problems for traditional scanning methods. We present a visible light tomographic ...
