Path Planning for Crowds: From Shared Goals to Individual Behaviors
(The Eurographics Association, 2005)This paper presents a novel approach for path planning in the context of crowds animation. The solution produces several paths joining each user-defined pair of locations in the environment. Pairs are possible initial/goal ... -
Perception-Based Rendering: Eyes Wide Bleached
(The Eurographics Association, 2005)Perception issues are a key factor in rendering Vision-Realistic images. This paper develops a novel spectral sensitive model of the Human Visual System (HVS) in order to simulate the bleaching effect in retinal photopigments. ... -
Photon Map Gathering on the GPU
(The Eurographics Association, 2005)Photon mapping methods obtain the indirect illumination of a point by finding those photon hits that arrived at the neighborhood of the point on the object surface. This paper proposes a method that stores the photon hits ... -
Predicting Natural Hair Shapes by Solving the Statics of Flexible Rods
(The Eurographics Association, 2005)This paper presents a new physically-based method for predicting natural hairstyles in the presence of gravity and collisions. The method is based upon a mechanically accurate model for static elastic rods (Kirchhoff model), ... -
Proactive Steering Toward Oriented Targets
(The Eurographics Association, 2005)In this paper we introduce a real-time steering controller ensuring the reach of a (possible mobile) target position and orientation, without requiring to build/update the full trajectory to that target. We name it the ... -
Progressive Cartesian Inequality Constraints for the Inverse Kinematic Control of Articulated Chains
(The Eurographics Association, 2005)We propose an Inverse Kinematic Control architecture capable of handling tasks that are expressed in terms of inequality constraints in the Cartesian space. These inequality constraints are progressive in the sense that ... -
Real-Time Marching Cubes on the Vertex Shader
(The Eurographics Association, 2005)In this paper we propose a new approach for visualizing volumetric datasets by their isosurfaces. For an interactive isosurface reconstruction an optimized version of the well-known marching cubes algorithm is used. We ... -
Real-Time Rendering of Cloudy Natural Phenomena with Hierarchical Depth Impostors
(The Eurographics Association, 2005)This paper presents a real-time method to realistically render dynamic participating media under changing lighting conditions. In order to cope with performance requirements, the volume is built of instances of particle ... -
Real-time Upper Body 3D Pose Estimation from a Single Uncalibrated Camera
(The Eurographics Association, 2005)In this paper we introduce a real-time steering controller ensuring the reach of a (possible mobile) target position and orientation, without requiring to build/update the full trajectory to that target. We name it the ... -
Rendering Realistic Trees and Forests in Real Time
(The Eurographics Association, 2005)Real-Time rendering of realistic trees on common graphics hardware represents a big challenge due to their inherent geometric complexity. In most cases, trees are composed of hundreds of thousands of leaves and branches ... -
A Scalable Hardware and Software System for the Holographic Display of Interactive Graphics Applications
(The Eurographics Association, 2005)We present a scalable holographic system design targeting multi-user interactive computer graphics applications. The display uses a specially arranged array of micro-displays and a holographic screen. Each point of the ... -
Scalar Tagged PN Triangles
(The Eurographics Association, 2005)This paper presents a new technique to convert a coarse polygonal geometric model into a smooth surface interpolating the mesh vertices, by improving the principle proposed by Vlachos et al. in their "Curved PN-Triangles". ... -
Sculpting in Augmented Reality
(The Eurographics Association, 2005)We present an Augmented Reality (AR) application which allows a user to manipulate a piece of virtual clay using a marker-free unencumbered hand. By removing the need to wear a glove or place markers on the hand the ... -
A Sharpness Dependent Approach to 3D Polygon Mesh Hole Filling
(The Eurographics Association, 2005)A sharpness dependent hole filling approach is proposed in this paper. The proposed method can fill the hole of a mesh-based model and recover its sharp feature located at the hole area. Interpolation based on radial basis ... -
Spherical Harmonic Lighting of Wavelength-Dependent Phenomena
(The Eurographics Association, 2005)Rendering of objects that exhibit iridescence has previously been limited to simple lighting conditions generated from a few point or directional lights. We extend this idea by modeling light interference as a Bidirectional ... -
Video Textures Exploiting Symmetric Movements
(The Eurographics Association, 2005)In this paper, an extension to the traditional method for creating video textures is presented. By exploiting the symmetric properties of the frames in a given video sequence, a new endless video stream or video loop is ... -
A Visual Quality Prediction Model for 3D Texture
(The Eurographics Association, 2005)Online bandwidth limitations and fluctuations impose a major challenge in estimating the amount of data to transmit in a given time period. Over or under estimation of bandwidth can jeopardize the visual fidelity of the ... -
Walking with Pens
(The Eurographics Association, 2005)Believable 3D animation of walking or running characters still requires complex motion capture technology or extensive skills in manual keyframing. We present an inexpensive, yet natural input method: The user walks on ...
