Therefore, the system has far-reaching significance and can be widely used.

Free Model of VR Interactive System
The system uses a six-degree-of-freedom control pen as the main interactive input method. The user selects an object through the virtual ray emitted from the position of the control pen. When the virtual ray is in contact with the object, press the corresponding interactive key and move the control pen to grab the part or zoom.
(1) Six degrees of freedom grasping In unity, the rotation of an object is described by a unit quaternion, and the expression is (w,x,y,x) q = , the operation between the quaternion and the vector needs to extend the vector to the quaternion space and express it in the form in formula (1). Before updating the position and angle of the object, the system calculates and caches the interactive initial information of the object: ray length d , the initial coordinate point of the object and the ray collision point p P Offset vector 0 v , and 1 − s q ,the product of the initial rotation angle of the object. Among them p P Is the coordinate of the ray collision point, which is obtained by (1) 0 ,P P s These are the initial coordinates of the control pen and the object at this time; s q , q 0 Are the initial rotation angles of the object and the control pen respectively; in formula (2) and formula (3), They are the inverse of the quaternion of the angle of the object and the control pen at this time, which are used to compensate for the offset caused by the first calculation of the loop; )] , , ,( Indicates the positive direction of the local coordinate system of the control pen. After the initial information is recorded, the updated rotation angle and position of the object are calculated by formula (4) and formula (5): During the above process pi P Is the ray i collision point coordinate of the first cycle si si q , P They are the position and angle of the control pen for the first cycle.
(2) Object zooms When the ray is in contact with the object, hold down the zoom key, and calculate the displacement of the Z axis of the local coordinate system of the control pen in real time to obtain the zoom ratio of the object, and dynamically assign it to the selected object. (

Virtual Reality Technology in Environmental Design Teaching (1) Changes in teaching mode
Construct virtual teaching solutions for environmental design majors based on VR technology, and introduce VR technology into practical teaching classrooms of environmental design majors in colleges and universities. Use virtual interactivity to change the mode of teachers speaking on stage and students listening in their seats, allowing teachers and students to participate in learning together. No longer blindly emphasize the completion of homework, but use virtual technology to change the traditional teaching mode, and use visualization technology to make the original complex and abstract concepts more intuitive, thereby improving teaching efficiency. The basic teaching process first introduces the case, and the teacher uses VR technology to guide students to conduct immersive learning on the topic; then the project guides to clarify the design requirements; then the virtual design platform is used for creative ideas until the design and development, and the final result is produced; and carry out exchanges and sharing to form the final result. Through the continuous teaching of the above mode, it can cover all the procedures and processes of the environmental design major in social practice, so that the content of classroom teaching is consistent with social practice, and it is easier for students to adapt to the rhythm of society. The resulting works also laid a solid foundation for subsequent learning.
(2) Changes in teaching methods The virtual reality technology practice teaching solution for environmental design majors can effectively solve the monotony of the current traditional teaching methods and fail to grasp the hearts of students. Let students use the virtual design platform to quickly show the effects of their design schemes, and at the same time, they can have an immersive experience in the virtual experience space, which improves students' learning interest. In the application of the teaching process, with the help of AR technology, teachers can use this system to integrate the concept of living space design, three major components, lighting and color in design principles, furniture and furnishings, design styles, etc.; materials and construction techniques, and residential housing the space design of the public buildings; the rationality of the space layout of public buildings and other related knowledge systems are reflected, thereby reducing the pressure of teacher preparation. Through the immersive experience, students can have a better understanding of the works they have designed; cultivate students' ability to explain their own designs.
(3) Change of studio construction model So far, students can only create an accurate feeling using computer 3D renderings. The virtual reality experience space developed based on VR technology allows users to combine virtual and reality interactions to enter the virtual space in the real scene, see every detail of the display and experience the actual feeling; it can also be achieved through virtual reality supporting software the interaction between virtual reality and the real world realizes the perfect combination of VR and IoT technology. In this way, when choosing a design plan, customers can experience a more realistic level, and they are more likely to prefer your design to choose your design plan. The virtual reality technology practice teaching solution for environmental design major changes the construction mode of university studios. Traditional design static studios are mostly displayed in the form of sample rooms, which are costly and have a single content. Students lack the experience of space, color, and materials. Use the design virtual experience space to make students' design plans and decoration effects get what they want.
(4) Change of project site practice methods Traditional project practice activities are greatly restricted by external conditions, some of the training operations are dangerous, inconvenient to repeat, and safety cannot be guaranteed. Most of them emphasize the completion of homework, which dampens the enthusiasm and enthusiasm of students in learning. Designing a virtual experience space allows students to experience actual projects in the entire virtual environment. Through the analysis of the core competencies of the environmental design major, the analysis is carried out around the necessary competencies of students. A series of digital training courses based on industry software and virtual simulation technology based on VR have been developed. Students will gradually master the skills required for environmental design jobs by completing tasks that combine virtual and reality.

Feel the future of the location after construction, and combine GIS information to know the surrounding situation and the outside environment more clearly the landscape has been designed and the surrounding environment combined with the overall planning design effect. In addition, many environmental companies are also using VR technology for in-depth applications in environmental-related fields.  Figure 2. The development stage of VR virtual reality technology As shown in Figure 2, domestic schools that truly apply virtual reality technology to regular campus courses are still rare, and they are still in the stage of collaborative research between key university laboratories and related technology companies. However, the application and promotion of virtual reality technology in campus courses is undoubtedly the trend of educational technology development and the direction of teaching method reform. It is to explore the effective combination of virtual reality technology and conventional courses, and play the role of curriculum education that combines virtual reality and reality. Obtaining effective teaching effects and promoting teaching reform are the issues that education researchers are concerned about and researched at this stage.  Table 1, VR technology has been widely used in environmental design education in recent years, with various forms and rich content. Its core is a virtual three-dimensional interactive experience space composed of computer hardware and software according to rigorous design thinking skills operation specifications. It enables users to produce the feelings of seeing, hearing, and touching, immersed in the virtual reality scene for training and assessment.
