The influencing factors of student satisfaction are obtained by using literature method and multivariate statistical analysis. These influence factors take into account both generality and individuality in different disciplines. Due to the number of influence factors is too large, the calculation burdens in evaluation need to be considered. Therefore, comprehensive determinants of students' satisfaction in discipline construction are defined in this paper. Comprehensive determinants of students' satisfaction in discipline construction are defined to be teachers' conditions, teaching conditions and practical conditions by principal component analysis method. Weights of comprehensive determinants in optimization evaluation are computed by entropy weight method. The experimental results verify the validity and feasibility of the optimization evaluation method of student satisfaction in discipline construction proposed in this paper.","PeriodicalId":294342,"journal":{"name":"2019 International Conference on Virtual Reality and Intelligent Systems (ICVRIS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129450156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By replacing the traditional word2vec word vector with Bert, richer semantic information is considered. The attention mechanism is introduced to consider the dependence between words on the basis of bilstm. At last, entity relation is extracted and entity relation triples are output. The experimental result shows that this method can deal with the overlap relation well and improve the result obviously.

VR film is an immersive, interactive and multi-perceived film created by VR technology. As a new form of film art, it attracts the attention of the audience and naturally brings the audience into the scene of the story. Make the audience the main body of the story. The emergence of VR movies has subverted the traditional movie viewing mode to a certain extent, bringing a new viewing experience to the audience. This paper analyzes the artistic characteristics of VR movies, and discusses the advantages and disadvantages: the lens language of VR movies, the richness of 360-degree scene elements and the immersive experience all lay a good foundation for the development of VR movies. basis. However, compared with traditional movies, VR movie plot design is relatively simple, the weakening of montage techniques and the dizziness and discomfort brought by VR headsets have become the limiting factors of VR movies. Technology production has become the main reason for restricting the development of VR movies. However, as a new technical means, VR technology has expanded the new artistic creation concept of the film, promoted the deep integration of art and technology, and enhanced the immersive and interactive experience of the film. In summary, in the future, VR film art creation should describe the story in a new VR lens language, scientifically and rationally arrange the story structure; pay attention to the user experience, give the audience a variety of sensory experiences through interactive design, and create a better immersive viewing experience. Improve the artistic creation and production capacity of film and promote the further development of VR film.","PeriodicalId":294342,"journal":{"name":"2019 International Conference on Virtual Reality and Intelligent Systems (ICVRIS)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125074312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To reduce the complexity of the model, it is necessary to make a fast visibility judgment before rendering the scene model and remove the important part of the real-time graphics display when the occluded elements are processed. A fast algorithm is proposed in this paper, which can deal with dynamic complex scenes. Real-time visibility judgment is made, and it is suitable for outdoor scenes with non-cavern structure. The algorithm organizes the whole scene with n-fork tree based on terrain using the idea of layering, and uses the double positioning method of linked list array to realize it. It not only saves the storage space effectively, but also locates the data nodes to be processed quickly, which greatly accelerates the process of view clipping and occlusion judgment.","PeriodicalId":294342,"journal":{"name":"2019 International Conference on Virtual Reality and Intelligent Systems (ICVRIS)","volume":"3 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123807359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
