Hyperslice Visualization of Metamodels for Manufacturing Processes
In the second phase of the Cluster of Excellence “Integrative Production Technology for High-Wage Countries” the Virtual Production Intelligence (VPI) platform is being developed. It is a holistic and integrative concept for the support of collaborative planning, monitoring and control of core processes within production and product development in various application fields. In the context of the VPI we are developing a tool for the explorative visualization of multi-dimensional meta-model data, which is based on the concept of hyperslices, linked with a 3D volume representation. The tool is applicable to various scenarios of multi-dimensional data analysis, but the concrete use case in the current project is to find ideal configuration parameters for laser cutting machines in the context of factory planning.VR Group
We developed a visualization and interaction concept, which is easy to learn and provides an understanding of high-dimensional data in different ways. On the one hand, a general understanding of the interdependencies between different configuration parameters is granted. On the other hand, it is possible to identify ideal configuration parameters for a certain use case in a fast, reliable, and simple manner. Both ways are made possible by providing interactive navigation and exploration of the data space, which is further supported by introducing methods to lead the user to points of interest, e.g., gradient trajectory navigation which guides the user to the next extrema in the multi-dimensional data space. The main challenge for the realization of this concept lies in the huge amount of data to be visualized. The computation time for slices through the data space rises exponentially with the number of dimensions and metamodels with seven or more dimensions are currently being created by future users. Interactive display can only be achieved by progressive rendering and advanced parallelization concepts.
