Interactive Rendering of Atmospheric Scattering Effects Using Graphics Hardware
(The Eurographics Association, 2002)
To create realistic images using computer graphics, an important element to consider is atmospheric scattering, that is, the phenomenon by which light is scattered by small particles in the air. This effect is the cause ...
Infinite Resolution Textures
(The Eurographics Association, 2016)
We propose a new texture sampling approach that preserves crisp silhouette edges when magnifying during close-up viewing, and benefits from image pre-filtering when minifying for viewing at farther distances. During a ...
Perlin Noise Pixel Shaders
(The Eurographics Association, 2001)
While working on a method for supporting real-time procedural solid texturing, we developed a general purpose multipass pixel shader to generate the Perlin noise function. We implemented this algorithm on SGI workstations ...
High-Quality Volume Rendering Using Texture Mapping Hardware
(The Eurographics Association, 1998)
We present a method Jor volume rendering of regular grids which takes advantage of 3D texture mapping hardware currently, available on graphics workstations. Our method products accurate shading for arbitrary and dynamically ...
Real-Time Bump Map Synthesis
(The Eurographics Association, 2001)
In this paper we present a method that automatically synthesizes bump maps at arbitrary levels of detail in real-time. The only input data we require is a normal density function; the bump map is generated according to ...
Extracting Microfacet-based BRDF Parameters from Arbitrary Materials with Power Iterations
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
We introduce a novel fitting procedure that takes as input an arbitrary material, possibly anisotropic, and automatically converts it to a microfacet BRDF. Our algorithm is based on the property that the distribution of ...
Using Flash Photography and Image-Based Rendering to Document Cultural Heritage Artifacts
(The Eurographics Association, 2016)
A novel image-based rendering system is proposed for documenting cultural heritage artifacts. The system utilizes backscattering photography to acquire the initial pictures and derives estimates for the object's diffuse ...
Visualization of Particle-based Data with Transparency and Ambient Occlusion
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
Particle-based simulation techniques, like the discrete element method or molecular dynamics, are widely used in many research fields. In real-time explorative visualization it is common to render the resulting data using ...
