If you are not familiar with perspective drawing, read our article on 3d drawing first.
Here is another view of the multilink structure discussed in 3D Drawing.
Draw it in two-point linear perspective.
Which properties of the original structure are preserved in your drawings, which are not? You should think about:
- the relationship between the lengths of the edges of the cubes
- the angles between them
- parallel and perpendicular lines
What do you think the advantages of linear perspective drawing are? What disadvantages are there with this method of representing 3D objects in 2D?
