Selective Inspection and Interactive Visualization of Light Transport in Virtual Scenes
(The Eurographics Association and John Wiley and Sons Ltd., 2012)
This paper presents novel interactive visualization techniques for inspecting the global light transport in virtual scenes. First, we propose a simple extension to photon mapping to gather required lighting information. ...
SHADOWPIX: Multiple Images from Self Shadowing
(The Eurographics Association and John Wiley and Sons Ltd., 2012)
SHADOWPIX are white surfaces that display several prescribed images formed by the self-shadowing of the surface when lit from certain directions. The effect is surprising and not commonly seen in the real world. We present ...
Iterative Image Warping
(The Eurographics Association and John Wiley and Sons Ltd., 2012)
Animated image sequences often exhibit a large amount of inter-frame coherence which standard rendering algorithms and pipelines are ill-equipped to exploit, limiting their efficiency. To address this inefficiency we ...
Metering for Exposure Stacks
(The Eurographics Association and John Wiley and Sons Ltd., 2012)
When creating a High-Dynamic-Range (HDR) image from a sequence of differently exposed Low-Dynamic-Range (LDR) images, the set of LDR images is usually generated by sampling the space of exposure times with a geometric ...
A Cell-Based Light Interaction Model for Human Blood
(The Eurographics Association and John Wiley and Sons Ltd., 2012)
The development of predictive appearance models for organic tissues is a challenging task due to the inherent complexity of these materials. In this paper, we closely examine the biophysical processes responsible for the ...
Coding Depth through Mask Structure
(The Eurographics Association and John Wiley and Sons Ltd., 2012)
We present a coded-aperture method based on a family of masks obtained as the convolution of one "hole" with a structural component consisting of an arrangement of Dirac delta functions. We call the arrangement of delta ...
Explicit Mesh Surfaces for Particle Based Fluids
(The Eurographics Association and John Wiley and Sons Ltd., 2012)
We introduce the idea of using an explicit triangle mesh to track the air/fluid interface in a smoothed particle hydrodynamics (SPH) simulator. Once an initial surface mesh is created, this mesh is carried forward in time ...
Importance Caching for Complex Illumination
(The Eurographics Association and John Wiley and Sons Ltd., 2012)
Realistic rendering requires computing the global illumination in the scene, and Monte Carlo integration is the best-known method for doing that. The key to good performance is to carefully select the costly integration ...
Repetition Maximization based Texture Rectification
(The Eurographics Association and John Wiley and Sons Ltd., 2012)
Many photographs are taken in perspective. Techniques for rectifying resulting perspective distortions typically rely on the existence of parallel lines in the scene. In scenarios where such parallel lines are hard to ...
SMAA: Enhanced Subpixel Morphological Antialiasing
(The Eurographics Association and John Wiley and Sons Ltd., 2012)
We present a new image-based, post-processing antialiasing technique, which offers practical solutions to the common, open problems of existing filter-based real-time antialiasing algorithms. Some of the new features include ...
