But the images can also be achieved also by using a piece of art paper or any blank sheet of paper, a pencil, or pen, and one good ruller, unless you are the kind of person that can draw very good straight lines.
The first simple trick to creat a 3D object without ever having to use a 3D Program is to draw a cube. As shown in the image below. Even when you look at a Dice you can not see all of its sides, but you can possition it to at least see three of it's sides. From the view point as drawn, this is the very basic of drawing in 3D.
Another great and by far the best technique and trick to truly create a more better 3D effect is shown in the image by the side of the cube. A corridor with three walls, a floor and a ceiling. And for extra added effect, a door at the very end. This image looks very much 3D.
This technique got used in comics to make near real looking buildings and city scapes, the same technique is used in catrtoons too. From the two basic forms of making flat art look like 3D, paved the way later on for making computer games. If I am not mistaken it was actually Tomb Raider that broke the mould of all console games of its generation.
Before that the best and only way to do 3D was used in the original Doom Game and that format was copied and used for the Alien Trilogy Game, that was also a Playstation One Title. It is hard, though not completely impossible to do other types of 3D looking images on a flat canvas, rather than on a 3D one.
I just wanted to share this wonderful knowledge with you and this art that shows that drawing things in 3D can be done with such simplicity. I hope you all like it?
