Visualization and analysis of multifunctional spatial transformation of virtual reality technology applied to cruise ship interior design

The study is based on VR technology to design the optimal layout plan for the building space. The cruise ship indoor space environment is projected into a two-dimensional x o y plane to determine the geometric features of the cruise ship indoor space and the layout attributes of the layout objects, and then the two-dimensional drawings are imported into the virtual reality platform to generate a three-dimensional spatial model of the cruise ship indoor space. According to the 3D spatial model, take the layout attributes of the layout objects as constraints, and construct one-to-one models of layout elements within different layout objects. The appropriate layout element model is selected in the database and imported into the virtual display platform for positioning and editing to generate the interactive effect of the layout scene of the cruise ship indoor space, and the binocular camera is used to carry out roaming control to realize the functions of revealing and hiding of the different layout elements in the layout objects, replacing the materials of the layout elements, as well as replacing and adjusting the different elements under the roaming control. The simulation results show that the optimal layout scheme can be obtained by using the above method, and compared with the original scheme, the optimized layout scheme of this paper’s method improves 4.59, 16.84 and 13.82 percentage points in the three dimensions of cabin adjacent strength, away strength and circulation strength respectively, which is of good applicability.
