Perception-based Lighting Design
(The Eurographics Association, 2006)
Perception-based lighting design approaches model image quality using a cognitively grounded objective function which is in turn optimised through manipulation of the lighting parameters of a scene. We present, and ...
Polynomial Approximation of Blinn-Phong Model
(The Eurographics Association, 2006)
The Phong model has been one of the oldest and the most popular reflection models in Computer Graphics. It can be used to model specular highlights of various materials. In this paper, we consider a polynomial model and ...
Out of core Polyhedral Union and its Application to Interactive Shadow Rendering
(The Eurographics Association, 2006)
Four methods for storing a set of points using a computer are currently known: Boundary representations, Constructive Solid Geometry, Binary Space Partitioning trees, and Nef polyhedra. We describe a time and spaceefficient ...
Expressive and Dynamic Deformation of Animated Computer-Generated Characters
(The Eurographics Association, 2006)
3D computer animated characters often lack the communicative power and the expressiveness of traditional animation, especially when used in non-photorealistic graphical representations. Inspired by a talk by Pixar Animation ...
Collision Detection for Deformable Objects using Octrees
(The Eurographics Association, 2006)
We present an algorithm for collision detection between multiple deformable objects translating in a large environment. We use Spatial Partitioning to subdivide the scene and a Bounding Volume Hierarchy to decompose the ...
State of the Art Non-Photorealistic Rendering (NPR) Techniques
(The Eurographics Association, 2006)
The emergence of non-photorealistic rendering (NPR) over the greater part of a decade has created an intriguing new field espousing expression, abstraction and stylisation in preference to the traditional computer graphics ...
Perceived Rendering Thresholds for High-Fidelity Graphics on Small Screen Devices
(The Eurographics Association, 2006)
Small screen devices, also known as small-form-factor (SFF) devices including mobile phones and ultra mobile PCs are increasingly ubiquitous. Their uses includes gaming, navigation and interactive visualisation. SFF devices ...
Flexible Interaction with Large Point-Based Datasets
(The Eurographics Association, 2006)
We present an application for interacting with large, point-based datasets built with commodity off-the-shelf hardware. Our system works on ordinary workstations with mouse and keyboard interaction as well as on immersive ...
Augmented Reality with Multilayer Occlusion
(The Eurographics Association, 2006)
An algorithm for realizing multilayer occlusion in augmented reality (AR) is presented in this paper. We have designed a special scene graph tree comprised of some special nodes, namely EMO nodes. According to the location ...
A Mixed Reality Anatomy Teaching Tool
(The Eurographics Association, 2006)
In this paper we present an inexpensive Mixed Reality software tool for training medical students in anatomy. The software integrates the ARToolkit and Visualization Toolkit (VTK) to create a novel interactive environment ...
