Introductions to the 0.

Virtual reality technology, also known as VR technology, is a comprehensive and integrated technology type. It was first applied in the late 20th century, including artificial intelligence, human interaction technology, computer technology, sensing technology and other different technology types. The application of virtual reality technology in THREE-DIMENSIONAL animation ultimately aims at integrating computer technology, Internet technology and other design methods to build a virtual environment and provide people with opportunities to explore the world and understand interesting space. Therefore, the application value of virtual reality technology is high, which marks the development trend of modern science and technology, and has a key impact on 3d animation production.

1. Overview of virtual reality technology

1.1 Basic Concepts

Virtual reality technology is a computer technology as the core, derived from the basic computer technology type, the magic, fantasy, real situation interlacing, forming a variety of perceptual experience technology application form. In the process of practical application technology, the use of virtual reality glasses, projection equipment with the use of physical space, perceptual experience is enhanced in the process of users in the movie, is the use of modern computer equipment, will turn their multifaceted human senses, realize effective coordination, network equipment, give a person a kind of immersive feel [1]. Virtual or reality itself are two opposite concepts. Virtual objects are used in the brain reconstruction process of reality, which provides users with the opportunity to enter the virtual world and bring them into the scene through sensory experience, finally forming a special form of interaction.

1.2 Technical Features

The characteristics of virtual reality technology are interactive, imaginative and immersive, and users have different sensory experiences in specific situations or environments. Of course, this environment is virtual construction, users have a good audio-visual experience, based on the environmental conditions created by technical means. The user has good sensory feedback and can form a real emotion based on the virtual environment. As shown in Figure 1 below, the characteristic of interaction is to interact with an object in a virtualized environment, and the accuracy and effectiveness of the interaction are strong in the process, which is also related to the immersion effect to some extent. The quality of imagination is that new feelings or ideas can still be obtained through the way of reproducing real scenes and passively receiving information. Users have the consciousness of active exploration and practice.

The essential connection between 3D animation technology and virtual reality technology

2.1 Differences between the two

3d animation technology uses the pre-set path of the computer to arrange still photos and play them continuously, forming a form of continuous play, which itself lacks interactivity. Therefore, in the process of viewing works, users always maintain a passive state, and then obtain the corresponding information content in the works, which is the main difference between 3D animation technology and virtual reality technology [2].

The foundation of the application of virtual reality technology is to provide dynamic information content around the needs of users. The computer can realize fast calculation and output sensory information needed by the experiencer, including touch, hearing, vision and other aspects. The experiencer's ideas can also be displayed in the process. So the essence of using 3d animation technology or virtual reality technology is the difference in interactivity. This difference is a technical breakthrough, and it is obviously different from traditional animation production, which is conducive to the development of China's animation cause.

The difference between the two is also reflected in the effectiveness of user needs and other aspects, virtual reality scenes will replace the authenticity, the overall computing speed is relatively fast, but will not affect the real-time dynamic changes, and can only meet the most basic visual authenticity needs. In order to avoid the computer having to deal with massive amounts of information content in the process, simplified models or basic forms are usually used to replace some objects in the scene to improve the computing speed of the computer. In 3d animation modeling, to show the artistic expression and authenticity of the model, many animation characters do not conform to the real situation in terms of facial proportions and body movements due to the pursuit of beauty or artistic treatment. There is also the creation of virtual characters and things, as shown in figure 2 below, such as the fantasy scenes in mobile games and costume dramas, can be shown through technical processing. Virtual reality pays more attention to reality, and the application of 3D animation technology should highlight the need of artistic creation. There are essential differences between the two.

2.2 Association between The two

Three-dimensional animation technology and virtual reality technology also have a certain internal connection, the foundation of virtual reality system construction, is the application of three-dimensional model in the virtual world, in the process of using the three-dimensional software in the computer implementation. This is similar to the application of 3D animation technology in modern animation production. At present, the development of information technology can provide 3d animation production software in various forms [3]. In the process of constructing virtual models or output images, 3D animation has a more ideal way of expression in the technical application stage. In the process of expression, the two have certain similarities, and the basis of technical processing is based on 3D graphics technology. The essence of virtual reality technology can show people's pursuit of 3D animation technology and the development direction set. Visible virtual reality technology, to some extent, is also the performance of the comprehensive development and innovative application of 3D animation technology.

3d animation technology and virtual reality technology can complement each other and have the characteristics of complementarity, which can be embodied in information interaction. Virtual reality technology combined with Internet technology, THREE-DIMENSIONAL graphics technology, hardware sensors and other technical means to achieve realistic scene construction, users and virtual reality system to complete spatial interaction, technical means to create a new world. 3d animation technology is not interactive enough, but pays more attention to the expression of artistic characteristics. Its own defects are repaired by using virtual reality technology to enhance the interaction and expressive force of art. 3d animation can show the virtual world after computer processing, and bring more real visual experience to the experiencer, which is also the basic condition for the completion of virtual reality.
