Real-time appearance preserving out-of-core rendering with shadows
(The Eurographics Association, 2004)Despite recent advances in finding efficient LOD-representations for gigantic 3D objects, rendering of complex, gigabyte-sized models and environments is still a challenging task, especially under real-time constraints and ... -
Lattice-Boltzmann Lighting
(The Eurographics Association, 2004)A new technique for lighting participating media is suggested. The technique is based on the lattice-Boltzmann method, which is gaining popularity as alternative to finite-element methods for flow computations, due to its ... -
An Efficient Hybrid Shadow Rendering Algorithm
(The Eurographics Association, 2004)We present a hybrid algorithm for rendering hard shadows accurately and efficiently. Our method combines the strengths of shadow maps and shadow volumes. We first use a shadow map to identify the pixels in the image that ... -
An Irradiance Atlas for Global Illumination in Complex Production Scenes
(The Eurographics Association, 2004)We introduce a tiled 3D MIP map representation of global illumination data. The representation is an adaptive, sparse octree with a "brick" at each octree node; each brick consists of 8 <sup>3</sup> voxels with ... -
Simulating Photon Mapping for Real-time Applications
(The Eurographics Association, 2004)This paper introduces a novel method for simulating photon mapping for real-time applications. First we introduce a new method for selectively redistributing photons. Then we describe a method for selectively updating the ... -
Feature-Based Textures
(The Eurographics Association, 2004)This paper introduces feature-based textures, a new image representation that combines features and samples for high-quality texture mapping. Features identify boundaries within an image where samples change discontinuously. ... -
Programmable Style for NPR Line Drawing
(The Eurographics Association, 2004)This paper introduces a programmable approach to non-photorealistic line drawing from 3D models, inspired by programmable shaders in traditional rendering. We propose a new image creation model where all operations are ... -
Smooth Reconstruction and Compact Representation of Reflectance Functions for Image-based Relighting
(The Eurographics Association, 2004)In this paper we present a new method to reconstruct reflectance functions for image-based relighting. A reflectance function describes how a pixel in a photograph is observed depending on the incident illumination on the ... -
Light Space Perspective Shadow Maps
(The Eurographics Association, 2004)In this paper, we present a new shadow mapping technique that improves upon the quality of perspective and uniform shadow maps. Our technique uses a perspective transform specified in light space which allows treating all ... -
Rendering Evolution at Industrial Light and Magic
(The Eurographics Association, 2004)From Jurassic Park to Van Helsing, the rendering technologies at ILM have evolved over the last 10 years, both to satisfy the high demands of our clients and also those of the general public. State-of-the-art rendering ... -
Practical Rendering of Multiple Scattering Effects in Participating Media
(The Eurographics Association, 2004)Volumetric light transport effects are significant for many materials like skin, smoke, clouds, snow or water. In particular, one must consider the multiple scattering of light within the volume. While it is possible to ... -
Animatable Facial Reflectance Fields
(The Eurographics Association, 2004)We present a technique for creating an animatable image-based appearance model of a human face, able to capture appearance variation over changing facial expression, head pose, view direction, and lighting condition. Our ... -
An Analytical Model for Skylight Polarisation
(The Eurographics Association, 2004)Under certain circumstances the polarisation state of the illumination can have a significant influence on the appearance of scenes; outdoor scenes with specular surfaces - such as water bodies or windows - under clear, ... -
Bixels: Picture Samples with Sharp Embedded Boundaries
(The Eurographics Association, 2004)Pixels store a digital image as a grid of point samples that can reconstruct a limited-bandwidth continuous 2-D source image. Although convenient for anti-aliased display, these bandwidth limits irreversibly discard important ... -
Hardware Accelerated Visibility Preprocessing using Adaptive Sampling
(The Eurographics Association, 2004)We present a novel aggressive visibility preprocessing technique for general 3D scenes. Our technique exploits commodity graphics hardware and is faster than most conservative solutions, while simultaneously not overestimating ... -
All-Frequency Relighting of Non-Diffuse Objects using Separable BRDF Approximation
(The Eurographics Association, 2004)This paper presents a technique, based on pre-computed light transport and separable BRDF approximation, for interactive rendering of non-diffuse objects under all-frequency environment illumination. Existing techniques ... -
Alias-Free Shadow Maps
(The Eurographics Association, 2004)In this paper we abandon the regular structure of shadow maps. Instead, we transform the visible pixels P(x, y, z) from screen space to the image plane of a light source P0(x0, y0, z0). The (x0, y0) are then used as sampling ... -
A Self-Reconfigurable Camera Array
(The Eurographics Association, 2004)This paper presents a self-reconfigurable camera array system that captures video sequences from an array of mobile cameras, renders novel views on the fly and reconfigures the camera positions to achieve better rendering ... -
Efficient Rendering of Atmospheric Phenomena
(The Eurographics Association, 2004)Rendering of atmospheric bodies involves modeling the complex interaction of light throughout the highly scattering medium of water and air particles. Scattering by these particles creates many well-known atmospheric optical ... -
Rendering Forest Scenes in Real-Time
(The Eurographics Association, 2004)Forests are crucial for scene realism in applications such as light simulators. This paper proposes a new representation allowing for the real-time rendering of realistic forests covering an arbitrary terrain. It lets us ...
