In this tutoriaal we will learn how to create
3D shapes using
Adobe Illustrator and
Adobe Photoshop software. The main idea of this tutorial is to explore the Adobe Illustrator's 3d feature and making a design using adjustments in Photoshop.

So here we are in Adobe illustrator CS4. Create a document.

Create a round angled rectangular shape using shape tools. The shape will be filled with blue color.

Go to the
Effects>Illustrator effects>3D>Extrude and Bevel.
Watch my settings. In this mini window you can transform illustrator shapes and make them 3D. The good or (for somebody) bad thing is that you will set the Perspective Distortion angle manually all the time. You can also control the light intensity and place lights as well.

So with my settings applied I got this result (the shape on the background).

Of course this is not V.ray render quality for 3d, but still it is a good way if you want to use 3D in your 2D based image.
As you can see I got the other shape waiting to be transformed and 3D distorter in perspective.
And here are my settings on the other shape.

You have maybe noticed that some of the settings are different: for example I've added bevel border and set the lights different. Moreover the light intensity is changed too.

And here we have 2 equal shapes with different 3D perspective distortion, lighting and shared color (the initial color is Blue).
To go a little bit further I suggest you to drop low intense shadow.

To the botch of the objects:

Now I still want to create that 3rd object and to distort is different from these 2.
Here are the settings first:

First thing that is changed here
