Construction of 3D model for ship industry design based on virtual reality
In order to achieve higher quality ship industrial design and enhance its interactive effect in virtual environ-ments,a method for constructing 3D models of ship industrial design based on virtual reality is studied.Adopting a systemat-ic hierarchical design method,the ship model is divided into five core areas to achieve precise model construction and effi-cient management.Using virtual reality technology,a three-dimensional model of a ship is constructed through steps such as data collection,3D Max modeling,model optimization,material mapping rendering,and output.In the modeling process,collision detection is carried out using motion navigation and solid bounding box technology based on assembly geometric constraints to ensure accurate assembly of the model and avoid collision phenomena.At the same time,dynamic level of de-tail(LOD)technology is introduced to dynamically adjust the level of detail of the model based on the distance between the observer and the model,in order to improve rendering efficiency and reduce system resource consumption.The experiment-al results show that this method can establish high-quality ship 3D models,which can display real lighting and shadow ef-fects,as well as detailed textures of parts such as the hull and deck,and improve the smoothness of ship 3D model rendering.
