Abstract
Abstract This paper establishes different detail-level terrain grids for different terrain data blocks and generates multi-resolution terrain based on the tree-structured LOD model as a way of layering large-scale terrain data. Then, the virtual environment’s visual and image texture are rendered to visualize the virtual spatial environment. Then, the overall architecture of the interaction platform was designed, and the virtual space design visualization and interaction effects were studied based on spatial distance perception, presence experience perception, and error analysis. The results show that there is a significant difference between the mean value of people’s perceived satisfaction in the interaction space and non-interaction space M=163.138, t=1.376, p=0.005<0.05. The error in the interaction of the system in this paper is between (0.2 and 1.8), which indicates that the system performs well. This study of interaction design research proposes a new research dimension for the traditional interaction interface based on virtual reality technology, which provides an effective reference basis for future related designs.
