How do you distinguish between 3D art in visual art and 3D art in digital art?

1. Visual 3D art is used to describe all of the visual arts while all 3D digital art is only for movies.
2. There is no way that digital art can be 3D while some forms of visual art can be 3D.

3. Visual 3D art objects have physical depth, while 3D digital art just appears to have depth.

4. In digital art, 3D describes the final product instead of a type of art.​
