Abstract:

[Objective]To solve a series of problems brought about by large-scale scientific data visualization, and to provide a flexible and scalable scientific data visualization framework, this paper proposes GPVis, a scientific visualization system for large-scale data. [Methods]In this paper, we analyzed the challenges and opportunities faced by scientific data visualization at both the method and tool level. A new visual computing and service framework, GPVis, is proposed by using advanced technologies such as data pre-organization, graphics rendering, high-performance computing, human-computer interaction, VR/AR, etc.. [Results]For some common visualization methods, this paper proposes several visualization processing models for GPVis framework, and enumerates several application cases of the system in typical fields with provided specific implementation methods and results. In these cases, different types of visualization need of scientific researchers for data analysis were met. [Limitations]GPVis needs more intelligence for data analysis which leads us to incorporate artificial intelligence technology into future developments and introduce more natural human-computer interaction methods. [Conclusions]GPVis provides a powerful and scalable platform framework for large-scale scientific data visualization, enabling flexible component design for different data types and application requirements. As the system continues to evolve by providing more complete framework functions and visualization algorithms, it will be applied to more scientific fields in the future.
