vtkPointCloud

VTK's vtkPointCloud is a software tool used in visualization to represent and display collections of points in 3D space—think of it as a digital scatter of dots. It allows users to handle large amounts of spatial data, often used in fields like medicine, engineering, or research, to analyze shapes, surfaces, and structures. By processing and rendering point data efficiently, vtkPointCloud helps visualize complex patterns and details within 3D environments, facilitating better understanding and analysis of spatial information without requiring detailed surface models.
