Mathematically it should be correct to render with a orthographic camera
and later transform the image. I think this is the easiest method when
you have multiple objects (so you do not have to [add modifiers to each][1]).
First you should shear in 2D (skewing) the rendered image then (if needed)
stretch to get the correct aspect.

Most [raster graphics editors][8] have the tools to preform the above
transformations. This can also be done in the compositor using a
Blend texture and the Displace node.
