g-BRDFs: An Intuitive and Editable BTF Representation
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Measured reflection data such as the bidirectional texture function (BTF) represent spatial variation under the full hemisphere of view and light directions and offer a very realistic visual appearance. Despite its ... -
G1 Hierarchical Bezier Surface over Arbitrary Meshes
(Blackwell Publishers Ltd and the Eurographics Association, 1999)This paper presents a method for constructing composite surfaces based on a collection of quadrilateral patches. A global parameterization using bilinear quadrilateral meshes and FEM like minimization procedure are introduced. ... -
G1 Smoothing Solid Objects by Bicubic Bezier Patches
(Eurographics Association, 1988)A general and unified method is presented for generating a wide range of 3D objects by smoothing the vertices and edges of a given polyhedron with arbitrary topology using bicubic Bezier patches. The common solution to the ... -
G2 Surface Interpolation Over General Topology Curve Networks
(The Eurographics Association and John Wiley and Sons Ltd., 2014)The basic idea of curve network-based design is to construct smoothly connected surface patches, that interpolate boundaries and cross-derivatives extracted from the curve network. While the majority of applications demands ... -
G2 Tensor Product Splines over Extraordinary Vertices
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present a second order smooth filling of an n-valent Catmull-Clark spline ring with n biseptic patches. While an underdetermined biseptic solution to this problem has appeared previously, we make several advances in ... -
GA-Sketching: Shape Modeling from Multi-View Sketching with Geometry-Aligned Deep Implicit Functions
(The Eurographics Association and John Wiley & Sons Ltd., 2023)Sketch-based shape modeling aims to bridge the gap between 2D drawing and 3D modeling by providing an intuitive and accessible approach to create 3D shapes from 2D sketches. However, existing methods still suffer from ... -
Game Level Layout from Design Specification
(The Eurographics Association and John Wiley and Sons Ltd., 2014)The design of video game environments, or levels, aims to control gameplay by steering the player through a sequence of designer-controlled steps, while simultaneously providing a visually engaging experience. Traditionally ... -
Gamut Mapping Spatially Varying Reflectance with an Improved BRDF Similarity Metric
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Recent spatially varying reflectance (svBRDF) printing systems can reproduce an input document as a combination of matte, glossy and metallic inks. Due to the limited number of inks, this reproduction process incurs some ... -
GANtlitz: Ultra High Resolution Generative Model for Multi-Modal Face Textures
(The Eurographics Association and John Wiley & Sons Ltd., 2024)High-resolution texture maps are essential to render photoreal digital humans for visual effects or to generate data for machine learning. The acquisition of high resolution assets at scale is cumbersome, it involves ... -
Garment Model Extraction from Clothed Mannequin Scan
(© 2023 Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd., 2023)Modelling garments with rich details require enormous time and expertise of artists. Recent works re‐construct garments through segmentation of clothed human scan. However, existing methods rely on certain human body ... -
Garment Modeling from a Single Image
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Modeling of realistic garments is essential for online shopping and many other applications including virtual characters. Most of existing methods either require a multi-camera capture setup or a restricted mannequin pose. ... -
Garment Motion Capture Using Color-Coded Patterns
(The Eurographics Association and Blackwell Publishing, Inc, 2005) -
Gauss Stylization: Interactive Artistic Mesh Modeling based on Preferred Surface Normals
(The Eurographics Association and John Wiley & Sons Ltd., 2021)Extending the ARAP energy with a term that depends on the face normal, energy minimization becomes an effective stylization tool for shapes represented as meshes. Our approach generalizes the possibilities of Cubic ... -
Gaussian Process for Radiance Functions on the S2$\mathbb {S}^2$ Sphere
(© 2022 Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd., 2022)Efficient approximation of incident radiance functions from a set of samples is still an open problem in physically based rendering. Indeed, most of the computing power required to synthesize a photo‐realistic image is ... -
Gaussian Product Sampling for Rendering Layered Materials
(© 2020 Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd, 2020)To increase diversity and realism, surface bidirectional scattering distribution functions (BSDFs) are often modelled as consisting of multiple layers, but accurately evaluating layered BSDFs while accounting for all light ... -
Gaze-driven Object Tracking for Real Time Rendering
(The Eurographics Association and Blackwell Publishing Ltd., 2013)To efficiently deploy eye-tracking within 3D graphics applications, we present a new probabilistic method that predicts the patterns of user's eye fixations in animated 3D scenes from noisy eye-tracker data. The proposed ... -
A Gaze-enabled Graph Visualization to Improve Graph Reading Tasks
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Performing typical network tasks such as node scanning and path tracing can be difficult in large and dense graphs. To alleviate this problem we use eye-tracking as an interactive input to detect tasks that users intend ... -
GazeDirector: Fully Articulated Eye Gaze Redirection in Video
(The Eurographics Association and John Wiley & Sons Ltd., 2018)We present GazeDirector, a new approach for eye gaze redirection that uses model-fitting. Our method first tracks the eyes by fitting a multi-part eye region model to video frames using analysis-by-synthesis, thereby ... -
