Which term refers to a 3D representation of an object as perceived from a specific viewpoint?

The term that refers to a 3D representation of an object as perceived from a specific viewpoint is indeed the perspective view. This viewing technique simulates how the human eye perceives objects, creating an illusion of depth and space. In perspective views, parallel lines appear to converge at a vanishing point, which adds realism to the representation. This method is particularly useful in visualizing how an object would appear in the real world, where the position of the observer affects the appearance of the object.

In contrast, orthographic views depict objects using multiple flat projections from different angles without accounting for depth, making them less realistic but useful for technical drawings. Dimetric views involve a specific angle where two axes are scaled equally while the third axis is scaled differently, but it still does not offer the same depth perception as a perspective view. Isometric views represent an object with the three principal axes equally foreshortened and the angle between them typically set at 120 degrees, which also lacks the realistic depth that a perspective view provides.
