The computer imitates a pencil
Lesson 3.
One more way of pencil imitation. A way with application of plug Deep Paint ( Right Hemisphere). By the way the program can also work independently.

Many now speak about Deep Paint as the program with big opportunities in the field of imitation. I think, that not without justification, as the ready installations in it allow from ready image to get sets of traditional art styles. I want to tell about a principle of work in this program. If you create imitation of a certain performance for example a pencil, a pastel, a water color and so forth.

You should know how to work with this tool or material. You should simulate work of the certain tool on a tablet and if it is not present a mousy, in parallel the program simulates the figure on the screen. That's all if to speak in large about Deep Paint.

Let's take as usually an image of an object prepared at computer modeling.
Stages of creation an imitation by a pencil is the same, as in the description on the second lesson:
1. A stage of shading which reveals the form of object through light and shadow.
2. A stage of creating a planimetric figure of the object.
Let's create on the computer these two stages separately, and then combine them together.

Let's take a ready image, and we shall open it in bitmap editor PHOTOSHOP. In my example it is a project of a small public building. We shall begin our work with shading of our future figure. We shall make the duplicate of our image Image, "Duplicate'. We shall transfer this duplicate to program Deep Paint.


In the command panel of program Deep Paint we shall add layer above our image. In this new layer we shall create also a shaped figure. The program will clone figure from Base Layer in Layer2 again created by us thus in a copy new characteristics will be set. In our lesson it is adjustment of a pencil.

To see this process and for convenience of controlling it we shall make image, Base layer with which we are going to do the imitation transparent. For this purpose we shall establish a toddler of function Opacity on 14 %

Now, in the command panel of modes of operation presets we shall establish in the list of modes the option Cloners to simulate, and in the bottom list of this window we shall choose simulator Pencil Cloner.
It is possible to play adjustments of the characteristic of a pencil such as color, etc.. but if you are a beginner do not do it so the command already assumes by default installations Pencil Cloner executed by experts.

Let's pass in the command panel to Layer2 where we want to simulate our figure in technique of a pencil. Having chosen tool Clone in tools panels Tools we start to simulate movement of a pencil on top of our image.

We shall see that on Layer2 there are strokes reminding strokes of a pencil. It is necessary to do a direction movement by a mousy, on a direction to reveal planes and shadows.

With Tool Rotate you can turn the figure around, and Pan Zoom to move away or closer or reduce the image. Having even small skills in drawing you receive the image reminding my picture.

Open image file of the primary source. With the help of distort filter Find Edges from the set of filters Stylize transform our figure in linear. We shall take advantage of dialogue window Fide and establish a mode of mixing of colors Lighten. We shall remove lines which are very close to light tones, having applied option Levels. We apply command Desaturate to make our image of grey color. In detail all these actions are described in lesson 2. part 2.

Now it is necessary to combine together our images created at the two previous stages.

We shall choose a planimetric image commanding Select all and by command Copy we shall copy it. Now we shall open image where we have created the shaped figure and commanding Paste we shall load in it the image with planimetric lines. Now we see the image as a layer laying under background layer Background.

Choose an overlying layer and make it Multiply to combine it with the bottom layer.

Now we combine existing layers by command Flatten Image whish is in menu Layers. In detail these actions are described in lesson 2. part 3. We have received a basic figure imitated on the computer as pencil figure.

If to continue work on further figures and to make some additions it is possible to receive a quite completed figure composition by pencil of the object taken by me.

All described ways are not any secret. It is only some ways for application of technologies by separate computer programs. I can tell with confidence, that it is possible to create sets of various variants of linear figures and not only, for example, with filter High Pass- which perfectly separates high-contrast areas of the image from low contrast, but I think that I shall tell about it next time...
