Creating complex 3D objects

Today I want to tell you how to create any 3D image you want from a simple image – a blank (This lesson is relevant for users of Adobe Photoshop CS5 Extended.

one.A bit of theory without which nothing …
All three-dimensional (3D) objects that we want to create must first be drawn in Photoshop in grayscale. What does it mean? It’s simple, three-dimensional objects in Photoshop are drawn on the basis of specified colors that lie from black to white, but always in grayscale (not to be confused with a black and white image). The screenshot below shows this range of colors:

It is this color spectrum that is working to create 3D objects.
The darker you choose a color, the bigger the dent will be in the 3D object, and vice versa, the brighter the selected color is, the more this place will rise on the 3D object. In this way we can create reliefs, bulges and concavities on a 3D object.
It should be noted that all 3D objects have a standard geometric set in four directions:
– plane
– two-sided plane
– cylinder
– scope
on the basis of which models are built, based on what model we have to build. This means that having a blank in the form of a pattern in grayscale, we can build from it four different shapes. In order to understand all this, let’s move on to practice.

2Preparation of the working environment of the program for work.
If you have not yet enabled OpenGL rendering, enable the acceleration of three-dimensional objects: Edit> Preferences> Performance, tick and click Ok.

We need a palette for working with 3D objects. If you do not have it, do the following: Window> 3D.

3. Creating a blank.
Create a new drawing: File (File)> New (Cntr + N)), set the following parameters:

You can set other parameters, but remember, the larger our image, and its resolution the harder and longer the computer will process our figure.

Draw on the canvas with a brush with hard edges and a large diameter by pressing the Shift key, the following image (choose the color for each strip that I have shown in the screenshot):

This is our drawing – blank.

4. Creating 3D objects.
In the palette of 3D objects, make these settings, and click create:

Look at the figure that turned out:

Now rotate it with the tools:

As you can see, darker colors are planted deeper, and lighter ones, on the contrary, are more pushed forward. Try to analyze the figure, looking at our workpiece and comparing it with the figure.

Now return the state when we had a simple blank. In the palette of 3D objects, set these options now, and press the create button:

Look at the figure that turned out:

As you can see, darker colors are planted deeper, and lighter ones, on the contrary, are more pushed forward. Try to analyze the figure, looking at our workpiece and comparing it with the figure.

Now again, return the state when we had a simple blank. In the palette of 3D objects, set these options now, and press the create button:

Look at the figure that turned out:

As you can see, darker colors are planted deeper, and lighter ones, on the contrary, are more pushed forward. Try to analyze the figure, looking at our workpiece and comparing it with the figure.

Now again, return the state when we had a simple blank. In the palette of 3D objects, set these options now, and press the create button:

Look at the figure that turned out:

As you can see, darker colors are planted deeper, and lighter ones, on the contrary, are more advanced in front. Try to analyze the figure, looking at our workpiece and comparing it with the figure.

five. Now I think you understand the principle on which Photoshop builds three-dimensional objects. To consolidate the material, I will show the following example:

In order for us to recreate the same, we must analyze it as follows: From above and below the figure, there is a place of average diameter relative to the whole figure, which means that on the workpiece it should be an average color (not very dark, not very light). Further, the drum with hollows means the drum is the most convex and it means that the color on the blank is the lightest (but not too light because the diameter of the drum will be excessively large). Very deep depressions to the base indicate that the color of the depressions should be black or so on the blank. Well, of course, of the four options for constructing figures (plane, two-sided plane, cylinder, sphere), we choose – a cylinder. On the basis of these analyzes I create such a blank:

Using logical thinking, we can create absolutely any 3D shapes. I would like to advise you to practice. Imagine in mind any fictional figure and arguing as I did, reproduce the blank and build a figure on its basis, see if it matches the figure you planned, if not, try again and this way you will get the skill of working with 3D objects and you can easily create shapes according to your idea.

I wish you success, I hope you enjoyed the lesson. My other lessons on 3D modeling can be found here.
