Research And Application Of VR Technology In Calculus Visualization

With the development of modern Internet technology and information technology,people's learning and teaching methods have changed unprecedentedly.On the one hand,the demand for online education has increased rapidly in recent years.For students,in distance learning,it is impossible to communicate with teachers face-to-face in the way of offline learning.How to understand the knowledge learned online as soon as possible is the problem they need to solve.On the other hand,blackboard books in traditional classroom education limit the teaching speed and expression methods of teachers.Students need to get knowledge faster,while teachers need to find ways to improve teaching efficiency.As an important development direction of computer visualization technology,virtual reality technology has higher authenticity in knowledge visualization than general graphic courseware,solves the incomplete problem of general plane visualization,and has important significance in providing more vivid visual teaching materials for education and learning.Firstly,this paper takes mathematical function image as the research object,analyzes the definition and expression of mathematical function drawing function,and gives the realization tool of drawing mathematical function image based on Unity3 D drawing principle.At the same time,aiming at the definition of the binary function and the binary function,the definition of the one-dimensional parameter equation and the binary parameter equation,the paper designs the corresponding visual image generation program combining with its definition,which can show its geometry directly through the image.Then,according to the knowledge of calculus,this paper analyzes the image expression forms of continuous,differential and integral knowledge points,and designs the differential image expression and integral image expression of one variable function and two variable function.Finally,this paper constructs a virtual reality visualization system,summarizes and summarizes each independent drawing scene,designs a simple navigation scene,and realizes the switching between the scenes.At the same time,this paper realizes the virtual roaming of3 D drawing scene,which provides users with an all-round viewing angle and intuitively and stereoscopically explains the geometric meaning of knowledge points.Finally,the system can be released as the application of computer and mobile application.The virtual reality visualization system designed in this paper is convenient and simple,which basically covers the common function drawing requirements,whether it is self-study of students or the development of courseware assisted teaching by teachers.At the same time,each drawing module of the virtual reality visualization system is designed independently,which is not interfered with each other,and the module is convenient and simple to add,which provides the possibility for the later system content expansion.
