Mixing Fluids and Granular Materials
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
Fluid animations in computer graphics show interactions with various kinds of objects. However, fluid flowing through a granular material such as sand is still not possible within current frameworks. In this paper, we ...
Range Scan Registration Using Reduced Deformable Models
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
We present an unsupervised method for registering range scans of deforming, articulated shapes. The key idea is to model the motion of the underlying object using a reduced deformable model. We use a linear skinning model ...
Table-based Alpha Compression
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
GPU-Based Volume Ray-Casting with Advanced Illumination
(The Eurographics Association, 2009)
Volume Abstract raycasting techniques are important for both visual arts and visualization. They allow an efficient generation of visual effects and the visualization of scientific data obtained by tomography or numerical ...
GPU Ray-Casting for Scalable Terrain Rendering
(The Eurographics Association, 2009)
With the ever increasing resolution of scanned elevation models, geometry throughput on the GPU is becoming a severe performance limitation in 3D terrain rendering. In this paper, we investigate GPU ray-casting as an ...
Teaching Quaternions is not Complex
(The Eurographics Association, 2009)
Quaternions are used in many fields of science and computing, but teaching them remains challenging. Students can have a great deal of trouble understanding essentially what quaternions are and how they can represent ...
Shadowing Dynamic Scenes with Arbitrary BRDFs
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
We present a real-time relighting and shadowing method for dynamic scenes with varying lighting, view and BRDFs. Our approach is based on a compact representation of reflectance data that allows for changing the BRDF at ...
Temporal Glare: Real-Time Dynamic Simulation of the Scattering in the Human Eye
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
Glare is a consequence of light scattered within the human eye when looking at bright light sources. This effect can be exploited for tone mapping since adding glare to the depiction of high-dynamic range (HDR) imagery on ...
Importance Sampling Spherical Harmonics
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
In this paper we present the first practical method for importance sampling functions represented as spherical harmonics (SH). Given a spherical probability density function (PDF) represented as a vector of SH coefficients, ...
