# FAQ: How To Draw Optical Illusions For Beginners?

## How to draw a floating / levitating cube

Jonathan Harris’ How To Draw Your Hand In 3D tutorial compresses 15 minutes of work into two minutes. Anamorphic optical illusion: a floating/levitating cube.

## How draw 3D pictures step by step?

1. Begin by sketching a rectangle.
2. Continue this process to the far right side of the rectangle.
3. With a darker pencil or pen, trace around the image and erase all unwanted pencil marks.
4. Lightly sketch in a second set of steps on the left side.

## What is a 4D drawing?

4D Draw is a simple vector graphics app that allows you to draw four-dimensional figures by representing the first three coordinates of each point in the traditional way and using color to represent the fourth coordinate. It is designed for geometry students who want to learn to visualize four-dimensional space.

## Why is the impossible triangle impossible?

The Impossible Triangle cannot exist because it would require the violation of Euclidean geometry rules, such as the bottom bar of the tribar being spatially located to both the front and back of the tribar’s topmost point.

## How do you make an impossible shape?

How Do I Draw Impossible Shapes? Impossible shapes are a type of optical illusion.

1. Draw a triangle.
2. Extend a line from each corner.
3. Draw another line from each of those extensions that extends a bit over the corners.
4. We’re almost done!
5. Now comes the fun part: Connect the lines to create an impossible shape!

## What is the impossible triangle illusion?
