VTK Tutorial: Exploring Example Source Code

VTK (Visualization Toolkit) is a powerful open-source software library commonly used in scientific visualization and computer graphics. It provides a comprehensive set of tools and algorithms for creating, manipulating, and rendering 3D visualizations. In this tutorial, we will explore one of the example source codes provided in the VTK documentation and provide a detailed explanation.

Before we dive into the source code, let’s briefly discuss the basic structure of a VTK program. A typical VTK program consists of several key components, including:

1. Data Source: This component generates or loads the input data that will be visualized. It could be geometric primitives, image data, or any other form of structured or unstructured data.
