Mecklenburg, Robert | STORY: A hierarchical animation and storyboarding system for alpha-1 | We introduce an integrated animation and storyboarding system that simplifies the creation and refinement of computer generated animations. The framework models both the process and product of an animated sequence, making animation more accessible for communication and as an art form. The system a... | STORY; storyboarding system; animation system; computer generated animations | 1993 |

Parke, Frederic Ira | Computer generated animation of faces | This report discusses the representation, animation and data collection techniques that have been developed and used to produce "realistic" computer generated half-tone animated sequences of a human face changing expression. It was determined that approximating the surface of a face with a polygona... | Computer animation | 1972-06 |

Kopta, Daniel M.; Kensler, Andrew Erin; Spjut, Josef Bo; Brunvand, Erik L.; Davis, Al | Fast, effective BVH updates for dynamic ray-traced scenes using tree rotations | Bounding volume hierarchies are a popular choice for ray tracing animated scenes due to the relative simplicity of refitting bounding volumes around moving geometry. However, the quality of such a refitted tree can degrade rapidly if objects in the scene deform or rearrange significantly as the ... | Ray tracing; Acceleration structures; Bounding volume hierarchies; Tree rotations; Dynamic scenes; Parallel update | 2011 |

Bargteil, Adam Wade | Dynamic sprites | Traditional methods for creating dynamic objects and characters from static drawings involve careful tweaking of animation curves and/or simulation parameters. Sprite sheets offer a more drawing-centric solution, but they do not encode timing information or the logic that determines how objects shou... | 2014-01-01 | |

Potter, Kristin Carrie | Uncertainty visualization in forward and inverse cardiac models | Quantification and visualization of uncertainty in cardiac forward and inverse problems with complex geometries is subject to various challenges. Specific to visualization is the observation that occlusion and clutter obscure important regions of interest, making visual assessment difficult. In orde... | 2013-01-01 | |

Bargteil, Adam Wade | Deformation embedding for point-based elastoplastic simulation | We present a straightforward, easy-to-implement, point-based approach for animating elastoplastic materials. The core idea of our approach is the introduction of embedded space-the least-squares best fit of the material's rest state into three dimensions. Nearest neighbor queries in the embedded spa... | 2014-01-01 | |

Hansen, Charles D. | Design of 2D time-varying vector fields | Design of time-varying vector fields, i.e., vector fields that can change over time, has a wide variety of important applications in computer graphics. Existing vector field design techniques do not address time-varying vector fields. In this paper, we present a framework for the design of time-vary... | 2012-01-01 | |

Miller, Jan D.; Lin, Chen-Luh | Scientific visualization in mineral and material processing | Scientific visualization is an ideal methodology for investigating complex phenomena that are characterized by large amounts of data. Furthermore, it is invaluable in the study of processes that evolve in time. Scientific visualization relies heavily on computer graphics, image processing and video... | Air sparged hydrocyclone flotation; Ball mill grinding; Tomography; Computer graphics | 1993 |

Parke, Frederic Ira | A parametric model for human faces | This report presents a computer model for the representation of human faces. This three-dimensional, parametric model produces shaded facial images. The face, constructed of polygonal surfaces, is manipulated through the use of parameters which control interpolation, translation, rotation and scalin... | Parametric model; Human face | 1975 |

Peterson, John W. | Distributed computation for computer animation | Computer animation is a very computationally intensive task. Recent developments in image synthesis, such as shadows, reflections and motion blur enhance the quality of computer animation, but also dramatically increase the amount of CPU time needed to do it. Fortunately, the computations involved w... | Distributed computation | 1987 |

Furse, Cynthia M.; Lazzi, Gianluca; Gandhi, Om P. | Electrical energy absorption in the human head from a cellular telephone | The antenna of a cellular telephone in close proximity to the human head for a variety of time periods raises questions. This research uses finite-difference time-domain (FDTD) method to calculate the power deposition from a cellular telephone on a high-resolution model of a human head as measured b... | Finite-difference time-domain method; FDTD; Power deposition; Human head model; Electrical energy absorption; Specific absorption rate | 1996 |

Thulasinathan, Aravindan; Pascucci, Valerio; Tierny, Julien | Topology Based Surface Meshing and Morphing | Morphing is a seamless transition from one image to the other, used in animation and motion pictures. Mesh Parameterization used in this process is a fundamental tool used for domain remeshing. In case of 2-manifolds for example, most approaches require that the input mesh be cut into one or mor... | 2010-10-06 | |

Bargteil, Adam Wade | Strain limiting for clustered shape matching | In this paper, we advocate explicit symplectic Euler integration and strain limiting in a shape matching simulation framework. The resulting approach resembles not only previous work on shape matching and strain limiting, but also the recently popular position-based dynamics. However, unlike this pr... | 2014-01-01 | |

Bargteil, Adam Wade | Multiphase flow of immiscible fluids on unstructured moving meshes | In this paper, we present a method for animating multiphase flow of immiscible fluids using unstructured moving meshes. Our underlying discretization is an unstructured tetrahedral mesh, the deformable simplicial complex (DSC), that moves with the flow in a Lagrangian manner. Mesh optimization opera... | 2014-01-01 | |

Tasdizen, Tolga; Whitaker, Ross T. | Particle-based simulation of fluids | Due to our familiarity with how fluids move and interact, as well as their complexity, plausible animation of fluids remains a challenging problem. We present a particle interaction method for simulating fluids. The underlying equations of fluid motion are discretized using moving particles and th... | 2003 | |
