Can we represent multiple scenes from a real-world coordinate system on the viewport? If yes, how?
By using multiple viewports
By using multiple window ports
Both a. and b.
No, we cannot represent multiple scenes from a real-world coordinate system on the viewport
Correct Answer :
A. By using multiple viewports
To display different sections of the scene, we use multiple viewports so that different sections can be displayed on different parts of the screen.
