A state machine for real-time cutting of tetrahedral meshes

A state machine for real-time cutting of tetrahedral meshes

pacific conference on computer graphics and applications

作者： D. Bielser P. Glardon M. Teschner M. Gross Computer Graphics Laboratory ETH Zurich Switzerland

We introduce an algorithm that consistently and accurately processes arbitrary intersections in tetrahedral meshes in real-time. The intersection surfaces are modeled up to the current cut tool position at every point in time. Tetrahedra are subdivided by using a progressive method, which inserts the required sub-structures step by step. A state machine tracks the topology of each tetrahedron and controls the progressive subdivision. In order to keep the state machine as small and clear as possible, each topological pattern of a tetrahedral intersection appears only once. These topological patterns are mapped onto the actual case of a tetrahedral intersection by some given transformation operations. The state transitions, which contain the specific subdivision operations, are described in a predefined lookup table, which is written in a simple script language. The handling of reverse movements and possible trembling of the users hand, as well as a recursive continuation of the state machine concept, complement the proposed algorithm. In three examples, covering free form modeling, volume visualization, and surgery simulation, we indicate the large field of applications in which our algorithm can be utilized.

In this paper, we propose efficient numerical techniques for Butterworth filtering and implicit fairing of large irregular triangle meshes, where the corresponding filters are rational polynomials and the resulting large linear systems need to be solved iteratively. We show that significant speed-up can be achieved for Butterworth filtering by factorizing the linear system in the complex domain. As for implicit fairing, with our estimate of the optimal extrapolation parameter /spl omega/, successive overrelaxation (SOR) offers great improvements, both in speed and space usage, over the more familiar conjugate gradient type solvers.

Interactive modeling of tree bark

Interactive modeling of tree bark

ISBN: (纸本)0769520286

There exist many computer graphics techniques which could achieve high quality tree generation. However, only few works focus on realistic modeling of tree bark. Difficulties lie in the complex appearance of the bark surfaces from a single image. We address three main issues here: feature specification; height field assignment; and texture correction. For feature specification, we use texton channel analysis to specify a variant of common bark features, inluding ironbark, vertical and horizontal fractures, tessellation, furrowed cork, and lenticels. For height field assignment, we develop an intuitive and easy-to-use user interface (UI). Here similarity-based texture editing is used for assigning height fields within a texton channel mask. For texture correction, we use the modeled height fields to eliminate the underlying lighting effects in a captured texture. Our modeling system is image-based: it takes as input a bark image and produces as output a textured height field representing a bark sample. We demonstrate that out method is an effective and easy-to-use technique to interactively model a variety of photo realistic bark surfaces.

Lightweight face relighting

Lightweight face relighting

作者： S. Paris F.X. Sillion L. Quan CNRS INPG INRIA UJF ARTIS GRAVIR IMAG France HKUST Hong Kong China

We present a method to relight human faces in real time, using consumer-grade graphics cards even with limited 3D capabilities. We show how to render faces using a combination of a simple, hardware-accelerated parametric model simulating skin shading and a detail texture map, and provide robust procedures to estimate all the necessary parameters for a given face. Our model strikes a balance between the difficulty of realistic face rendering (given the very specific reflectance properties of skin) and the goal of real-time rendering with limited hardware capabilities. This is accomplished by automatically generating an optimal set of parameters for a simple rendering model. We offer a discussion of the issues in face rendering to discern the pros and cons of various rendering models and to generalize our approach to most of the current hardware constraints. We provide results demonstrating the usability of our approach and the improvements we introduce both in the performance and in the visual quality of the resulting faces.

作者： M. Shafae R. Pajarola Computer Graphics Laboratory School of Information & Computer Science University of California Irvine USA

DStrips is a simple and efficient method to dynamically manage and generate triangle trips for real-time view dependent multiresolution meshing and rendering. Progressive view-dependent triangle mesh simplification and rendering is an important concept for interactive visualization environments. To minimize the rendering cost, triangle meshes are simplified to the maximal tolerated perceptual error. A further savings can be gained by using hardware optimized rendering primitives such as triangle strips. However, triangle strips have been rarely used successfully in interactive multiresolution meshes due to the costs involved with maintaining the coherency of the strips n the changing mesh. This paper introduces a new dynamic triangle stripping data structure and algorithm. DStrips, that is practical for use with multiresolution meshes. DStrips is aimed at preserving pre-computed triangle strips through changes in the mesh and generating reasonably good triangle strips in real-time. Furthermore, this data structure and algorithm can be easily adapted to any multiresolution mesh which has a face-to-edge/edge-to-face mapping. The presented approach is implemented on top of a real-time view-dependent meshing and rendering framework based on a half-edge data structure using progressive edge collapses and vertex splits. Direct comparisons are made to previous methods in triangle stripification of dynamic and static meshes.

Physical touch-up of human motions

Physical touch-up of human motions

ISBN: (纸本)0769520286

Many popular motion editing methods do not take physical principles into account potentially producing implausible motions. This paper introduces an efficient method for touching up edited motions to improve physical plausibility. We start by estimating a mass distribution consistent with reference motions known to be physically correct. The edited motion is then divided into ground and flight stages and adjusted to enforce appropriate physical laws, for, respectively, zero moment point (ZMP) constraints and correct ballistic trajectory. Unlike previous methods, we do not solve a nonlinear optimization to calculate the adjustment. Instead, closed-form methods are used to construct a hierarchical displacement map which sequentially refines user-specified degrees of freedom at different scales. This is combined with standard methods for kinematic constraint enforcement, yielding an efficient and scalable editing method that allows users to model real human behaviors. The potential of our approach is demonstrated in a number of examples.

Realistic rendering of surface appearance using GPU

Realistic rendering of surface appearance using GPU

ISBN: (纸本)0769520286

Summary form only given. We present techniques for realistic modeling surface details and efficient rendering of the associated visual effects using programmable GPUs. An important topic in rendering surface appearance is the treatment of mesostructures, which are responsible for fine-scale shadowing, occlusion, inter-reflectance, and silhouettes. One way to model surface mesostructure is by using the bi-directional texture function (BTF), a 6D function that describes the appearance of a real-world surface as a function of lighting and viewing directions. We describe algorithms for efficient synthesis of BTFs on arbitrary surfaces and for hardware-accelerated rendering. Because the BTF can be measured from real-world surfaces, these algorithms allow us to texture 3D models with real-world textures. One issue with the BTF-based approach is that silhouettes of surface mesostructures are absent in the rendered images. This problem can be addressed by view-dependent displacement mapping, a technique for real-time rendering of displacement mapped surfaces using GPUs. We will present examples of our techniques shipped with major game platforms and some upcoming game titles.

Feature-based surface light field morphing

A surface light field is a function that gives the colors of each object point viewed from different directions. Object representation with a surface light field provides a nice structure for 3D photography. This paper presents a feature-based morphing technique for two objects equipped with surface light fields. The technique consists of geometry morphing and in-between light field mapping. Geometry morphing is accomplished by 3D mesh morphing, where we introduce a vertex merging technique to generate a simpler metamesh. In in-between light field mapping, an in-between object is rendered by extracting necessary fragments from input surface light fields. We also propose an acceleration technique for rendering an in-between object. Experimental results with real and synthetic data show natural and plausible morphing between objects with surface light fields. The proposed morphing technique can be used as an editing tool for 3D photography.

pacific conference on computer graphics and applications

作者： L. Kobbelt RWTH-Aachen Lehrstuhl fűr Informatik Aachen Germany

Summary form only given. The most important concepts for the handling and storage of freeform shapes in geometry processing applications are parametric representations and volumetric representations. Both have their specific advantages and drawbacks. While the algebraic complexity of volumetric representations is independent from the shape complexity, the domain of a parametric representation usually has to have the same structure as the surface itself (which sometimes makes is necessary to update the domain when the surface is modified). On the other hand, the topology of a parametrically defined surface can be controlled explicitly while in a volumetric representation, the surface topology can change accidentally during deformation. A volumetric representation reduces distance queries or inside/outside tests to mere function evaluations but the geodesic neighborhood relation between surface points is difficult to resolve. As a consequence, it seems promising to combine parametric and volumetric representations to effectively exploit both advantages. In this talk, a number of projects is presented and discussed where such a combination leads to efficient and numerically stable algorithms for the solution of various geometry processing tasks. applications include global error control for mesh decimation and smoothing, topology control for level-set surfaces, mesh repair, and shape modeling with unstructured point clouds.

Adaptive grouping and subdivision for simulating hair dynamics

pacific conference on computer graphics and applications

作者： K. Ward M.C. Lin Department of Computer Science University of North Carolina Chapel Hill USA

We present a novel approach for adaptively grouping and subdividing hair using discrete level-of-detail (LOD) representations. The set of discrete LODs include hair strands, clusters and strips. Their dynamic behavior is controlled by a base skeleton. The base skeletons are subdivided and grouped to form clustering hierarchies using a quad-tree data structure during the precomputation. At run time, our algorithm traverses the hierarchy to create continuous LODs on the fly and chooses both the appropriate discrete and continuous hair LOD representations based on the motion, the visibility, and the viewing distance of the hair from the viewer. Our collision detection for hair represented by the proposed LODs relies on a family of "swept sphere volumes" for fast and accurate intersection computations. We also use an implicit integration method to achieve simulation stability while allowing us to take large time steps. Together, these approaches for hair simulation and collision detection offer the flexibility to balance between the overall performance and visual quality of the animated hair. Furthermore, our approach is capable of modeling various styles, lengths, and motion of hair.
