Research on the Practical Application of VR and Computer Graphics in Design and Drawing Education Teaching and Learning Methods

VR and computer graphics are widely used in watching movies, games, military medicine, etc. By simulating the physical three-dimensional space through computers, events occurring in the space can be simulated to achieve an immersive effect. Therefore, it can be used as a pre-emptive drill to reduce fault tolerance rate. During the use of VR, 3D computer graphics are required for physical rendering to facilitate subsequent VR practice. The richness and experiential nature of VR effectively promotes learning motivation and can present times and experiences learned in textbooks that cannot be experienced in reality. Degrees of freedom (DoF) refers to how the viewer moves in three dimensions. In VR, viewers can freely change the position of the space. DOF allows creators to provide audience interaction features. Audiences who step on it can move around in the VR environment and receive messages and send messages to each other. After the activity, VR will be used as learning materials. It is necessary to master the way the audience watches in order to convey the desired message and avoid blind viewing, which will reduce the learning effect. This will provide different suggestions and references for future teaching or educational training to facilitate specific reference use in practical machine learning in the future, increase the learning effect and enhance learning interest and practical ability.
