How does an object's distance from the camera affect its scale in an orthographic projection? Why?

Answer :

Final answer:

In an orthographic projection, an object's distance from the camera affects its scale. As the object gets closer to the camera, its scale increases and it appears larger. Conversely, as the object moves farther away, its scale decreases and it appears smaller.

Explanation:

In an orthographic projection, the scale of an object is determined by its distance from the camera. As an object moves closer to the camera, its scale increases, making it appear larger. Conversely, as an object moves farther away from the camera, its scale decreases, making it appear smaller.

For example: Imagine taking a photograph of a person standing 10 feet away from the camera and then taking another photograph of the same person standing 50 feet away from the camera. In the first photograph, the person will appear larger because they are closer to the camera. In the second photograph, the person will appear smaller because they are farther away from the camera.

This change in scale occurs because the camera captures the same field of view regardless of the object's distance. So, when an object is farther away, it takes up less space in the frame, resulting in a smaller scale.
