3D drawing is a visual illusion trick your kid will love to learn.
By using the properties of depth perception, you can draw an object that looks like it’s jumping out of (or into) the 2D piece of paper.
It’s a great quiet time activity, too.
My child sat quietly at the table drawing lines for quiet some time.
It’s the perfect fine motor and concentration exercise.
What you need
- marker (any color)
- Trace the outline of a flower on the paper using a pencil.
- Draw parallel straight lines across the paper.
When you reach the outline, skip over the flower and continue drawing the straight lines on the other side of the flower.
- After you finish drawing parallel lines all over the paper, fill in the flower with curve lines.
Draw an arch between the point where the straight line ends on one side of the flower and the point where the straight line begins on the other side again.
Depth perception is our visual ability to perceive the distance of an object.
It allows us to perceive three dimensions (3D) in the world around us.
This line drawing technique makes use of curvilinear perspective to create depth perception so that a drawing on 2D surface is perceived to be 3D.
Here are more examples and technical explanation of this technique: Spherical Perspective
