Adaptive Progressive Vertex Tracing for Interactive Reflections
(Eurographics Association, 2001)This paper presents an approach for real-time rendering of physically accurate reflection effects in virtual environments. We apply a hybrid rendering of an OpenGL-generated scene, blended with correct reflection characteristics ... -
Fractal approximation of surfaces based on projected IFS attractors
(Eurographics Association, 2001)A method for approximating smooth or rough surfaces defined in R3 is introduced. A fractal model called projected IFS model allows the extension of the iteration space to a barycentric space Rn2 by enriching the classical ... -
Warped Textures for UV Mapping Encoding
(Eurographics Association, 2001)This paper introduces an implicit representation of the u; v texture mapping. Instead of using the traditional explicit u; v mapping coordinates, a non-distorted piecewise embedding of the triangular mesh is created, on ... -
Real-Time Procedural Animation of Trees
(Eurographics Association, 2001)Creating models of living flora, such as trees and grass, has been a challenge in computer graphics for many years. Animating these objects to move realistically in reaction to natural phenomena, such as wind and rain, ... -
Improved Rendering with Dégradé
(Eurographics Association, 2001)In most paintboxes drawing (and filling) the picture and render the picture are two different steps and tools. Dégradé presents an efficient filling rendering tool: an efficient collection of effect filling. In Dégradé the ... -
Virtual Actors’ Behaviour for 3D Interactive Storytelling
(Eurographics Association, 2001)In this paper, we describe a method for implementing intelligent behaviour for artificial actors in the context of interactive storytelling. We have developed a fully implemented prototype based on the Unreal™ game engine ... -
Occlusion Culling Methods
(Eurographics Association, 2001) -
Local Versus Global Triangulations
(Eurographics Association, 2001)Free form surfaces are commonly represented by triangular or quadrilateral meshes. Often these meshes are obtained from unorganized point sets sampled from some object’s surface. We show that local rather than global ... -
Rendering: Input and Output
(Eurographics Association, 2001)Rendering is the process of creating an image from numerical input data. In the past few years our ideas about methods for acquiring the input data and the form of the output have expanded. The availability of inexpensive ... -
Data driven motion transitions for interactive games
(Eurographics Association, 2001)In 3D video games that employ human characters, a series of animations is required to display a character’s motion. The current approach is to use stored animation sequences, either motion captured or hand animated, and ... -
A Microfacet Based Coupled Specular-Matte BRDF Model with Importance Sampling
(Eurographics Association, 2001)This paper presents a BRDF model based on the analysis of the photon collisions with the microfacets of the surface. The new model is not only physically plausible, i.e. symmetric and energy conserving, but provides other ... -
3dml: A Language for 3D Interaction Techniques
(Eurographics Association, 2001)We present 3dml, a markup language for 3D interaction techniques and virtual environment applications that involve non-traditional devices. 3dml has two main purposes: readability and rapid development. Designers can read ... -
Scalable Impressionist Rendering
(Eurographics Association, 2001)The painted impressionist technique produces scale based effects: the far range vision is almost realistic while the close vision is blurred. In NPR, Impressionist Renderers are mainly based on a medium range vision. A ... -
Approximated View Reconstruction Using Precomputed ID-Bitfields
(Eurographics Association, 2001)A technique is presented to construct arbitrary views of a model by using previously computed views. The technique is simple to implement, completely general for polygonal models and can be used within object hierarchies ... -
A Simple Validity Condition for B-Spline Hyperpatches
(Eurographics Association, 2001)The use of hyperpatches as a method for solid modelling has a problem: the validity of the model is not guaranteed. The problem of ensuring the validity of hyperpatch representations of solids is discussed in this work, ... -
Web 2D Graphics: State-of-the-Art
(Eurographics Association, 2001)The early browsers for the Web were predominantly aimed at retrieval of textual information. Tim Berners-Lee's original browser for the NeXT computer did allow images to be viewed but they popped up in a separate window ... -
Gaze-Contingent Level Of Detail Rendering
(Eurographics Association, 2001)The contributions of this paper are the development and evaluation of a nonisotropic model-based Level Of Detail (LOD) rendering technique for gaze-contingent viewing of multiresolution meshes. A high resolution portion ... -
Mesh Morphing
(Eurographics Association, 2001)Meshes have become a widespread and popular representation of models in computer graphics. Morphing techniques aim at transforming a given source shape into a target shape. Morphing techniques have various applications ... -
Collision Detection for Continuously Deforming Bodies
(Eurographics Association, 2001)Fast and accurate collision detection between geometric bodies is essential in application areas like virtual reality, animation, simulation, games and robotics. In this work, we address the collision detection problem in ...
