QNET: A Network for Lowdimensional Integrals of Neural Proxies
(The Eurographics Association and John Wiley & Sons Ltd., 2021)Integrals of multidimensional functions are often estimated by averaging function values at multiple locations. The use of an approximate surrogate or proxy for the true function is useful if repeated evaluations are ... 
QEMFiltering: A New Technique for FeatureSensitive Terrain Mesh Simplification
(The Eurographics Association, 2010)Terrain simplification generates multiresolution models, from which  traditionally  irregular or semiregular triangulations are extracted to render a terrain at a suitable level of detail. Recent terrain simplification ... 
Quad Layout Embedding via Aligned Parameterization
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Quad layouting, i.e. the partitioning of a surface into a coarse network of quadrilateral patches, is a fundamental step in application scenarios ranging from animation and simulation to reverse engineering and meshing. ... 
Quad Layouts via Constrained TMesh Quantization
(The Eurographics Association and John Wiley & Sons Ltd., 2021)We present a robust and fast method for the creation of conforming quad layouts on surfaces. Our algorithm is based on the quantization of a Tmesh, i.e. an assignment of integer lengths to the sides of a nonconforming ... 
Quad Layouts – Generation and Optimization of Conforming Quadrilateral Surface Partitions
(201412)The efficient, computer aided or automatic generation of quad layouts, i.e. the partitioning of an object’s surface into simple networks of conforming quadrilateral patches, is a task that – despite its importance and ... 
Quad Meshes as Optimized Architectural Freeform Structures
(201910)This thesis tackles the design of freeform surfacelike and loadbearing structures realized with cladding panels and supported by a framework substructure, often called gridshells. The actual fabrication of freeform ... 
Quad Meshing
(The Eurographics Association, 2012)Triangle meshes have been nearly ubiquitous in computer graphics, and a large body of data structures and geometry processing algorithms based on them has been developed in the literature. At the same time, quadrilateral ... 
QuadBased Fourier Transform for Efficient Diffraction Synthesis
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Farfield diffraction can be evaluated using the Discrete Fourier Transform (DFT) in image space but it is costly due to its dense sampling. We propose a technique based on a closedform solution of the continuous Fourier ... 
A QuadTree Algorithm for Displaying a 2Dimensional Slice of an NDimensional Weighted Voronoi Tessellation
(The Eurographics Association, 1986) 
Quad/Triangle Subdivision
(Blackwell Publishers, Inc and the Eurographics Association, 2003)In this paper we introduce a new subdivision operator that unifies triangular and quadrilateral subdivision schemes. Designers often want the added flexibility of having both quads and triangles in their models. It is also ... 
QuadCover  Surface Parameterization using Branched Coverings
(The Eurographics Association and Blackwell Publishing Ltd, 2007)We introduce an algorithm for the automatic computation of global parameterizations on arbitrary simplicial 2manifolds, whose parameter lines are guided by a given frame field, for example, by principal curvature frames. ... 
Quadratic Approximation of Cubic Curves
(ACM, 2020)We present a simple degree reduction technique for piecewise cubic polynomial splines, converting them into piecewise quadratic splines that maintain the parameterization and C1 continuity. Our method forms identical tangent ... 
A Quadratic Bending Model for Inextensible Surfaces
(The Eurographics Association, 2006)Relating the intrinsic Laplacian to the mean curvature normal, we arrive at a model for bending of inextensible surfaces. Due to its constant Hessian, our isometric bending model reduces cloth simulation times up to threefold. 
Quadratic Bezier Triangles As Drawing Primitives
(The Eurographics Association, 1998)We propose to use quadratic Bezier triangles as additional drawing primitives: quadratic Bezier triangles require much less model data for faithful representation of curved surfaces than planar triangles. Therefore, they ... 
Quadratic Contact Energy Model for Multiimpact Simulation
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Simultaneous multiimpact simulation is a challenging problem that frequently arises in physicallybased modeling of rigid bodies. There are several physical criteria that should be satisfied for rigid body collision ... 
Quadratic Encoding for Hand Pose Reconstruction from MultiTouch Input
(The Eurographics Association, 2015)One of the most compelling challenges in virtual reality today is to allow users to carry out virtual manipulation tasks using their hands. Multitouch devices are an interesting interface for this task, as they are widely ... 
Quadric Transfer for Immersive Curved Screen Displays
(The Eurographics Association and Blackwell Publishing, Inc, 2004)Curved screens are increasingly being used for highresolution immersive visualization environments. We describe a new technique to display seamless images using overlapping projectors on curved quadric surfaces such as ... 
QuadriFlow: A Scalable and Robust Method for Quadrangulation
(The Eurographics Association and John Wiley & Sons Ltd., 2018)QuadriFlow is a scalable algorithm for generating quadrilateral surface meshes based on the Instant FieldAligned Meshes of Jakob et al. (ACM Trans. Graph. 34(6):189, 2015). We modify the original algorithm such that it ... 
A Quadrilateral Rendering Primitive
(The Eurographics Association, 2004)The only surface primitives that are supported by common graphics hardware are triangles and more complex shapes have to be triangulated before being sent to the rasterizer. Even quadrilaterals, which are frequently used ... 
Quadrilateral Surface Mesh Generationfor Animation and Simulation
(Bommes, 20121011)Accurately describing the geometry of objects in a digital environment, i.e. computers, isan essential ingredient in many of nowadays applications. Often it is desired to forecastthe behavior of real phenomena which depend ...
