【摘要】：虚拟运动,是一种基于计算机数字技术的新型艺术创作方式。狭义上讲它是以运动规律为基础自动生成运动状态的表现形式,它根据对象的固有属性和运动规律,自动确定其运动状态并实现运动的再生。而近些年发展迅速的动作捕捉技术,为创造人类身体运动的虚拟提供了更完善的技术平台,它流畅准确地将人体的运动数据和生命信息记录下来,并通过创作者的想象力在虚拟场景中进行解析并重构了人体的运动方式,形成了一种全新的交互式审美艺术形态。基于动作捕捉的虚拟运动在数字电影、虚拟现实、网络游戏及体育训练等领域的应用广泛,改变了传统艺术形式给人所带来的身心体验,具有其自身的特点:实时的空间计算性、时空的自由与流动性以及它是一种多感知通道的体验模式。人在虚拟空间的实践过程中,身体受到所处境遇的运动速度、支点平衡、空间方向和作用力的影响,成为了这种创作形态不可缺少的一部分,它同时作为的接受者和表演者,表达着人们自身的思维和意向,用户身体通过视觉、听觉、触觉等途径获知虚拟空间的运动变化,并做以相应的反应,而作为“运动通路”的运动觉在这一过程中发挥了重要的作用,它与其它感知相配合,调节自身以维持空间及心理的平衡,并协调用户自身的运动表现。在人类艺术创作的历程中,人们始终为寻求生命运动的本质和表达方式不断的进行着探索。基于动作捕捉的虚拟运动,验证了生命本体与虚拟生命体之间的同构运动,这为探索并表达生命的本质提供了前所未有的可能性。它作为一种艺术创作方式呈现在现代媒介形态中,更直接的体现了人们对自身动作表现的渴望,在这种数字化构造的虚拟空间中,身体的内在秩序节奏、对时空的感知以及情绪冲动等体验得以充分的调动和激发,人们自然和本能地表达自身的生命体验。
[Abstract]:Virtual motion is a new art creation method based on computer digital technology. In a narrow sense, it is a form of expression that automatically generates the state of motion based on the law of motion, and it is based on the inherent attributes and laws of motion of objects. The rapid development of motion capture technology in recent years has provided a more perfect technical platform for the creation of virtual human body movement. It records the movement data and life information of human body fluently and accurately, and analyzes and reconstructs the human body's movement mode in virtual scene through the imagination of the creators, and forms a new interactive aesthetic art form. Virtual motion based on motion capture has been widely used in digital movies, virtual reality, online games and sports training, which has changed the physical and mental experience brought by traditional art forms. It has its own characteristics: real-time spatial computing, space-time freedom and mobility, and it is a multi-perception channel experience mode. In the practice of virtual space, the body is subjected to the movement speed of the situation, fulcrum balance, The influence of spatial direction and force has become an indispensable part of this creative form. It also acts as a receiver and performer, expressing people's own thoughts and intentions, and the user's body through vision and hearing. Tactile sense and other channels know the motion change of virtual space and react accordingly. As a "motor pathway", motion sense plays an important role in this process. Adjust oneself to maintain space and psychological balance, and coordinate user's own movement performance. In the course of human artistic creation, people are constantly exploring the essence and expression of life movement. The virtual movement based on action capture verifies the isomorphic movement between life ontology and virtual life. This provides an unprecedented possibility to explore and express the nature of life. It is presented in modern media as a form of artistic creation, and more directly reflects the desire of people to express their own actions. In this digital virtual space, the internal order rhythm of the body, the perception of time and space, the emotional impulse and other experiences can be fully mobilized and inspired, and people naturally and instinctively express their own life experience.
