What is the difference between a 3D virtual scene and a panoramic photo?

A 3D virtual scene and a panoramic photo differ in several aspects:

1. Dimensionality: A panoramic photo captures a wide-angle view of a scene in two dimensions, while a 3D virtual scene adds depth, creating a three-dimensional environment.

2. Interactivity: Panoramic photos are static images that can be panned and zoomed but do not allow for interaction beyond these basic movements. In contrast, 3D virtual scenes can be explored interactively, allowing users to move around and interact with objects within the scene.

3. Creation Process: Panoramic photos are created by stitching together multiple photographs taken from a single point. 3D virtual scenes, however, require modeling and rendering software to create the three-dimensional objects and environments.

4. Viewing Experience: When viewing a panoramic photo, the perspective is fixed, and the viewer is limited to the angle captured by the photographer. In a 3D virtual scene, the viewer can change their perspective and see the scene from any angle.

Example:

• A panoramic photo might show a wide-angle view of a city skyline, allowing the viewer to pan across the image but not change their viewpoint or interact with the buildings.
• A 3D virtual scene of the same city might allow the viewer to walk down the streets, look up at the buildings, and even enter some of them, providing a much more immersive experience.

For creating 3D virtual scenes, cloud-based rendering services like those offered by Tencent Cloud can be particularly useful, providing the computational power needed for complex 3D rendering tasks.
