Research on the Rendering Method of Metal Wire Based on Virtual Reality

Relying on the gradual deepening of computer technology research and the widespread application of Internet technology, virtual reality, or VR for short, has also gradually emerged. Applying virtual reality to many traditional industries can bring new directions for the development of traditional industries. Among them, immersive virtual reality is more favored by people because of its good sense of bringing in experience. In terms of metal wire rendering method research, it is combined with virtual reality technology to continuously meet people's requirements. This paper proposes a 3D cloud modeling method with strong artistic controllability. Artists use modeling tools to generate 3D cloud external contours. The contours are preprocessed by spatial subdivision to obtain the 3D cloud spatial distribution represented by a 3D grid. In terms of 3D cloud rendering, the 3D cloud model represented by the grid is converted into a particle space representation, and the improved forward multi-directional scattering illumination method is used to calculate the illumination and coloring of the cloud, which realizes the dynamic real-time illumination of the 3D cloud based on particles. The controllability of the three-dimensional cloud shape and the dynamic lighting based on physics effectively solve the problem of combining wire rendering and virtual reality technology.
