Which of the following is true of orthographic cameras?

The statement that orthographic cameras cannot render 3D meshes is misleading. Orthographic cameras can indeed render 3D meshes; they are commonly used in various applications, especially in 2D games or isometric projections where depth perception is not simulated.

The correct statement regarding orthographic cameras is that they provide a way to display 3D objects without the perspective distortion that a perspective camera would introduce. This means that objects are displayed in their true size regardless of their distance from the camera, which is essential in certain contexts where accurate measurements or uniform scaling is necessary.

While it is true that orthographic cameras do not simulate depth perception, this is not accurately captured in the choice that claims they cannot render 3D meshes. Understand that orthographic cameras are excellent for achieving a flat, uniform appearance, which is why they are used in specific game design scenarios and visualizations; they allow for depth to be perceived by layering objects, but they do not distort the size of objects based on their distance.
