Which statement is true regarding the visual perception of objects in orthographic projection?

The correct statement regarding the visual perception of objects in orthographic projection is that objects further away from the viewer appear to decrease in size. This statement reflects the fundamental principle of visual perception in both perspective and orthographic projections, though orthographic projection itself does not account for perspective distortion. In orthographic projection, dimensions and proportions remain consistent without the effects of perspective; however, the perception of distance can create an illusion of size change to the human eye based on the viewer’s spatial context.

In typical visual scenarios, objects that are perceived as being at a greater distance tend to appear smaller due to the way light and distance interact with our visual system. In practice, this is why items depicted as further away in a three-dimensional space might appear to decrease in size even if rendered consistently in two-dimensional orthographic views.

While equal distances would suggest that objects maintain the same size, this does not apply to variations in visual perception based on distance in the same way. Understanding these visual principles is critical in fields such as architecture and engineering, where accurately interpreting projections is essential.
