A Three-Dimensional Virtual Sand Table Framework Suitable for Industrial Parks

To address the issue of creating a virtual sand table that can only be interacted with and watched smoothly but cannot be edited, a mathematical algorithm combining LineRenderer components is proposed to realize the function of 3D annotation of graphics in the virtual sand table. Model surface reduction, radiographic inspection, and singleton mode enable scenario optimization. Given the interactive functions of the common virtual sand table, including animation, special effects, and data expression, and through the model surface reduction, radiographic detection, and singleton mode to produce a virtual sand table with exquisite scene quality, accurate data expression, smooth animation, incredible special effects, and strong interactivity, the feasibility of this scheme is verified using the three-dimensional virtual sand table of Wuzhou Trade and Logistics Park as an example.
