PC-based Real-time Texture Painting on Real World Objects
(Blackwell Publishers Ltd and the Eurographics Association, 2001)
The problem of texture mapping on real world objects has attracted attention11,8 recently. A work by Lensch et al.9 addressed the problem of locating a camera position in the celestial sphere and then mapping the acquired ...
Rendering Pearlescent Appearance Based On Paint-Composition Modelling
(Blackwell Publishers Ltd and the Eurographics Association, 2001)
We describe a new approach to modelling pearlescent paints based on decomposing paint layers into stacks of imaginary thin sublayers. The sublayers are chosen so thin that multiple scattering can be considered across ...
Flexible Image-Based Photometric Reconstruction using Virtual Light Sources
(Blackwell Publishers Ltd and the Eurographics Association, 2001)
Photometric reconstruction is the process of estimating the illumination and surface reflectance properties of an environment, given a geometric model of the scene and a set of photographs of its surfaces. For mixed-reality ...
A Dynamic Motion Control Technique for Human-like Articulated Figures
(Blackwell Publishers Ltd and the Eurographics Association, 2001)
This paper presents a dynamic motion control technique for human-like articulated figures in a physically based character animation system. This method controls a figure such that the figure tracks input motion specified ...
Interactive Rendering with Coherent Ray Tracing
(Blackwell Publishers Ltd and the Eurographics Association, 2001)
For almost two decades researchers have argued that ray tracing will eventually become faster than the rasterization technique that completely dominates todays graphics hardware. However, this has not happened yet. Ray ...
Automatic Lighting Design using a Perceptual Quality Metric
(Blackwell Publishers Ltd and the Eurographics Association, 2001)
Lighting has a crucial impact on the appearance of 3D objects and on the ability of an image to communicate information about a 3D scene to a human observer. This paper presents a new automatic lighting design approach for ...
Global Illumination as a Combination of Continuous Random Walk and Finite-Element Based Iteration
(Blackwell Publishers Ltd and the Eurographics Association, 2001)
The paper introduces a global illumination method that combines continuous and finite-element approaches, pre-serving the speed of finite-element based iteration and the accuracy of continuous random walks. The basic idea ...
Incremental Updates for Rapid Glossy Global Illumination
(Blackwell Publishers Ltd and the Eurographics Association, 2001)
We present an integrated global illumination algorithm including non-diffuse light transport which can handle complex scenes and enables rapid incremental updates. We build on a unified algorithm which uses hierarchical ...
Perceptually Guided Corrective Splatting
(Blackwell Publishers Ltd and the Eurographics Association, 2001)
One of the basic difficulties with interactive walkthroughs is the high quality rendering of object surfaces with non-diffuse light scattering characteristics. Since full ray tracing at interactive rates is usually impossible, ...
A Camera Engine for Computer Games: Managing the Trade-Off Between Constraint Satisfaction and Frame Coherence
(Blackwell Publishers Ltd and the Eurographics Association, 2001)
Many computer games treat the user in the "1st person" and bind the camera to his or her view. More sophistication in a game can be achieved by enabling the camera to leave the users' viewpoint. This, however, requires new ...
