A 3D walkthrough is a virtual tour or simulation that allows viewers to navigate and explore a digital representation of a physical space in three dimensions. It provides a realistic and immersive experience, often used in various industries such as architecture, real estate, gaming, and virtual reality.

In architecture, 3D walkthroughs are utilized to showcase building designs, interiors, and landscapes before construction begins. They enable clients to visualize the finished project and make informed decisions about design elements.

In real estate, 3D walkthroughs offer potential buyers a virtual tour of properties, allowing them to explore every corner and detail remotely. This technology enhances the property viewing experience and can be a valuable marketing tool.

In the gaming industry, 3D walkthroughs create interactive environments for players to navigate and experience. These simulations can range from realistic architectural environments to fantastical worlds in video games.

Overall, 3D walkthroughs provide an engaging and dynamic way to present and experience spaces digitally, offering a more immersive perspective than traditional 2D representations.
