o3d.visualization.draw_geometries()there are 2 types of draw_geometries()
1. draw_geometries(geometry_list, window_name='Open3D', width=1920, height=1080, left=50, top=50, point_show_normal=False, mesh_show_wireframe=False, mesh_show_back_face=False)
Function to draw a list of geometry.Geometry objects
Args:
geometry_list (List[open3d.geometry.Geometry]): List of geometries to be visualized.
window_name (str, optional, default='Open3D'): The displayed title of the visualization window.
width (int, optional, default=1920): The width of the visualization window.
height (int, optional, default=1080): The height of the visualization window.
left (int, optional, default=50): The left margin of the visualization window.
top (int, optional, default=50): The top margin of the visualization window.
point_show_normal (bool, optional, default=False): Visualize point normals if set to true.
mesh_show_wireframe (bool, optional, default=False): Visualize mesh wireframe if set to true.
mesh_show_back_face (bool, optional, default=False): Visualize also the back face of the mesh triangles.
Returns:
None
