Learning about perspective will let you fake it, as I did in the Hall of the Magic Wings. Trying to copy pictures that you like is a good way to begin teaching yourself about what looks good and what works. And even if you think that you can't draw, sit down and try. What will happen while you are trying to draw is that you will really start to see shapes and light and surfaces in 3D. Finally, remember critic Rebecca West's thought that what is required of art is not a copy of the world. The shapes you make in 3D can be used to express much more than just another chrome sphere on a checkerboard.
Art is the lie that tells the truth.
It's not the image that's left over when you are done. You are the art. Vidi , which, as a parting beau geste, is offering its very good 3D program as a free download. Beyond suggesting these, this is as simple a start to 3D as I can offer. I hope it helps.
