Data Driven Reactive Modelling: Summary We live in a world where computer graphics plays an ever increasing part. Whether it is interacting with a video game or simulating a delicate surgical operation, accurate models of real world objects are required. In recent history, models that appear realistic have satisfied the movie and games industries, but for simulations of surgical procedures or fighting forest fires models that behave in a realistic fashion are necessary. Although the advent of the Graphics Processor Unit (GPU) has enabled current models to be realistically rendered in real time, the architecture of these machines is designed around paradigms for modelling that were built decades ago. Paradigms based on meshes of tiny triangles were not designed to represent objects by their volume nor by their behaviour. In this research we seek new paradigms to describe models that exist in a real or artificial world, but can react to their surroundings, behaving realistically alongside real objects in an enhanced or virtual reality situation. Such a paradigm may not fit within the pipeline that is supported by current GPU technology. Indeed, new pipeline architecture could well be a future extension of this research. Much work in computer graphics looks only at solving immediate problems to produce realistic games or movies. In this research we look ahead to future decades where accurate simulation, for example of the human body, and all the physical interactions such a simulation might involve, can be supported in real time. We wish to find new methods to ease the task of representation, design and animation of 3D models, particularly where the model has to conform to a number of physical and aesthetic constraints, and in animation, where the constraints can change in real time. The result will be a reactive model, whose behaviour takes account of the world in which it exists. The near future goal is to extend the concept of implicit modelling, in which models are represented as an iso-surface in a scalar field. Such a field can be generated from geometric and other primitives, which can be derived from data or interactive input, or a combination of the two. By designing suitable functions the combination of fields and their gradients can yield complex, reactive models. Our most recent work combined mesh and implicit modelling to achieve the most accurate, real time, automatic skin deformations to date in an animated character. We wish to extend this work as well as search for a more suitable paradigm that will bring together knowledge from several disciplines, including computer graphics, vision, HCI and artificial intelligence. We also look beyond the theoretical to application areas such as a soft tissue simulation that will enhance training in fields such as neurosurgery.

数据驱动的反应性建模：摘要 我们生活在一个计算机图形上发挥不断提高的世界。无论是与视频游戏互动还是模拟精致的手术操作，都需要精确的现实世界对象模型。在最近的历史上，看起来现实的模型满足了电影和游戏行业，但是对于手术程序或与以现实方式行事的森林火灾模型的模拟是必要的。尽管图形处理器单元（GPU）的出现已经使当前模型实时渲染，但这些机器的体系结构是围绕数十年前建造的范式设计的。基于微小三角形的网格的范例并非以其体积或行为来表示对象。在这项研究中，我们寻求新的范式来描述在真实或人造世界中存在的模型，但可以对其周围的环境做出反应，并在增强或虚拟现实情况下现实地与真实物体一起行事。 这样的范式可能不适合当前GPU技术支持的管道。确实，新的管道体系结构很可能是这项研究的未来扩展。在计算机图形方面，很多工作只着眼于解决逼真的游戏或电影的直接问题。在这项研究中，我们展望了未来的几十年，可以实时支持准确的模拟，例如人体的准确模拟，例如人体的所有物理相互作用。 我们希望找到新的方法来简化3D模型的表示，设计和动画的任务，尤其是该模型必须符合许多物理和审美约束，并且在动画中，约束可以实时改变。 结果将是一个反应性模型，其行为考虑了其存在的世界。不久的将来的目标是扩展隐式建模的概念，其中模型在标量字段中表示为ISO地表。可以从数据或交互式输入或两者的组合中得出的几何和其他原始素生成这样的字段。通过设计合适的功能，场及其梯度的组合可以产生复杂的反应性模型。 我们最近的工作结合了网格和隐式建模，以实现迄今为止动画角色迄今为止最准确，实时，自动皮肤变形。我们希望扩展这项工作，并寻找更合适的范式，该范式将汇集来自几个学科的知识，包括计算机图形，视觉，HCI和人工智能。我们还可以超越理论上的应用领域，例如软组织模拟，该区域将增强诸如神经外科手术等领域的训练。
