Design of Lightweight Training System for Rail Transit Public Works Based on WebGL

Under the contradiction between the current rail transit line construction mileage growth rate and the traditional relatively inefficient talent training output methods, this paper designs a WebGL-based virtual reality lightweight training system based on the status quo of urban rail transit public works maintenance, and discusses Feasibility of various optimization techniques. Through on-the-spot research and inspection, refined modeling is carried out for rail transit scenarios, and model file types, loading methods and caching mechanisms are compared and tested. Meet the system fluency and assessment objectivity requirements.
