How to Create a 3D Drawing

The author of the tutorial is Liu Hui-zeng (China).

Using AKVIS Sketch you can create wonderful pencil sketches, watercolor paintings, and charcoal drawings. But the potential of the program doesn't end there! It's always great to discover fresh or unconventional ways of using the software.

This tutorial demonstrates how you can convert a simple photo into a 3D drawing.

• Step 1. We need two shots of the same scene taken from slightly different camera angles. These two images form a stereo pair.

  If necessary, adjust contrast, saturation, and sharpness. Put the images on separate layers.

  In our case:

  Layer 1 - an image for the left eye,
  Layer 2 - an image for the right eye.

• Step 2. Call the AKVIS Sketch plugin and turn both images into the drawings. You can use any settings.

• Step 3. To generate a three-dimensional image, isolate the color channels on each layer. You need two images, which are colored in mutually complementary colors (for example, in red and blue).

  Double-click on a layer and select the appropriate channel in the Blending Options.

  For the layer 1 - Red:

  For the layer 2 - Green and Blue:

• Step 4. Align the first image to the second image. As a result, we receive a red-cyan anaglyph:
  
  Red-Cyan Anaglyph

  To view the anaglyph in stereo, you need a special anaglyph glasses. The most common glasses have a red left lens and cyan right lens. With the glasses on, the brain fuses the two images provided to it by each eye separately into perception of a three-dimensional scene.
