Development of VR web-based solutions to support aerospace simulations

3D simulations play a crucial role in the aerospace domain, both for visualizing telemetry data and for enabling interactive operations based on acquired sensor data. These simulations provide intuitive representations that support system monitoring, anomaly detection, and structural analysis during mission planning and execution. This thesis, carried out at ALTEC, focuses on the development of a TypeScript library and two web-based tools designed to support 3D data visualization and reconstruction of simulated aerospace scenarios on web pages. The TypeScript library enables the seamless integration of Unity WebGL builds into Vue.js applications. It manages the Unity instance lifecycle and establishes a bidirectional communication layer between the simulation environment and the front-end. This facilitates the integration of interactive visualization within a web interface. The first tool is a benchmarking framework for evaluating surface reconstruction algorithms applied to LiDAR-generated point clouds. Based on an existing library, it includes a synthetic data generation pipeline using a virtual LiDAR simulator and a dataset of CAD models representing real satellite structures. The framework enables the systematic comparison of remeshing techniques and supports the optimization of algorithm parameters to improve reconstruction quality. The final goal of the tool is to provide ALTEC with an optimized remeshing algorithm. The second tool is a visualization system for detecting geometric discrepancies between scanned meshes and their reference CAD models. By computing deviations and rendering them as a color-coded heatmap on the reconstructed surface, the system highlights potential structural anomalies such as missing components or deformations. Together, these components form a complete pipeline for data processing and visualization. A demonstration scenario simulating a satellite scanning operation was developed to validate the tools and illustrate their integration in a realistic aerospace context.
