        <!--<p style="text-align: justify;">The simulated point clouds are generated to approximate real-world airborne LiDAR acquisition, explicitly modeling occlusion effects, visibility constraints, and other scanning-related phenomena to enhance realism.</p>

        <h2 style="text-align: center;">Mesh</h2>
        <!--<p style="text-align: justify;">The mesh is represented as a simplified triangular surface mesh, where the geometry is approximated using a set of connected triangular facets. This representation reduces geometric complexity while preserving the overall structural shape of the building.</p>
