Research And Implementation Of Real-Time Cloth Animation In 3D Engine

Recent years, cloth animation is becoming a hotspot for computer graphics and virtual reality field. With the improvement of computer software and hardware level, cloth animation technology has been further developed.However, how to simulate a vivid, stable and reliable, full of dynamism and real-time cloth animation effect in complex, interactive environments (such as 3D games) is a new challenge.Combined with practical project, this paper designs and implements the three dimensional animation of cloth components. In order to get the effect of the cloth animation, this paper has completed the following aspects of the content:1. This paper uses the particle spring modeling method to set up the corresponding physical animation model, and through the force analysis of the particles, and establishs the dynamic equation of the cloth.2. This paper presents a numerical integration method for solving speed fabric kinetic equation between accuracy and computational efficiency of the cloth animation to achieve an effective compromise.3. In order to ensure the authenticity of the cloth simulation and real-time, and solve the cloth fabric overlapping problems which arise collision itself, we use fixed direction surrounding body (FDH, Fixed Direction Hull) method which is more suitable for soft body collision detection and realized the fabric self-collision bounding volume tree by constructing FDH.The software engineering idea is used in the paper. The general module of the cloth animation simulation is abstracted. The independent component is formed. The Gamebryo game engine is used to draw three-dimensional animation, and the effect of adding shadow and illumination. At the same time, the paper has provided the technical support for the development of soft body function in the project, and achieved good results in the adaptability.
