A Tool for the Visualization of Variant Structures in Virtual Reality
Over time models and tools had to be developed to comprehend the increasing complexity of technological systems and their variant components. In this paper, we present a vision and a design for a VR tool that visualizes these variant structures and provides the tools for collaborative review and development. The tool is especially suited for feature models and product structures. We analyze different visualization methods and their fit for virtual space as well as techniques to reduce visual clutter and improve clarity. Our technical approach and schedule for development and evaluation is outlined and the application design is explained in detail. The proposed visualization is based on a cone tree layout in adjustable orientation and features a multi-instance system for convenient display of cross-tree constraints between remote subtrees. A gesture-based input system complements established interaction concepts and the tool supports CAD-model import for engaging collaborative work in immersive virtual experience.
