What is the main feature of virtual walkthroughs?

Virtual walkthroughs are primarily designed to allow users to explore a location in a three-dimensional (3D) representation. This immersive experience enables individuals to navigate through virtual spaces as if they were physically present, providing a more engaging and interactive way to experience environments compared to traditional 2D images or static representations.

In a virtual walkthrough, users can move through spaces, examine details from various angles, and interact with different elements within the environment, which provides a sense of scale and depth. This feature is particularly useful in various fields, such as architecture, real estate, gaming, and education, where conveying the spatial experience is essential.

The other options do not capture the essence of virtual walkthroughs. While visualizing a 2D image or controlling a character's movements can be part of other multimedia applications, they do not encompass the core functionality of virtual walkthroughs, which is the exploration of a fully immersive 3D space. Similarly, creating music environments is unrelated to the visual spatial exploration that virtual walkthroughs emphasize.
