Lesson Details

How-do-you-do, this is Ethan Nguyen for My Cartoon Tutorials.com and in this video, I'm going to show you how to describe a 3D hole optical illusion. Here'southward what the illusion will wait similar. 3D Hole Optical Illusion Drawing 1 At present let me testify you how I did it.

Step 1 – Cartoon the Ellipses

The first step is to draw a large ellipse. The rest of the drawing will be done in ink, but I will draw this first ellipse in pencil because we will exist erasing information technology later on. 3D Hole Optical Illusion Drawing 2 Next, depict a smaller ellipse within the start one using ink. You'll want to make this 1 slightly shorter and more rounded. And instead of placing it correct in the heart, move it downwardly slightly. By the manner, I made a calorie-free pencil sketching of the unabridged drawing earlier hand and is now simply going over it with ink. That style, the drawing process will exist a lot smoother and you won't have to meet me erasing and re-drawing a bunch of times. But when you're drawing this yourself, don't be agape to change things effectually a agglomeration of times to go the curves just right. Then draw another smaller ellipse inside this one. Again, y'all'll desire to make it more rounded and identify information technology closer towards the lesser. 3D Hole Optical Illusion Drawing 4 Repeat this process three more times. You tin see the pattern very clearly hither. Each ellipse is a little more than like a circumvolve and they group together at a single point.

Pace 2 – Drawing the Tiles

Adjacent, we're going to draw some straight lines from the heart outward. 3D Hole Optical Illusion Drawing 6 The gaps between these lines will be widest at the bottom and gradually narrow equally they motility upwardly. To assistance planing out the spacing and make them more consistent, I like to start at both ends at the same time. That way I'll have a practiced idea of how broad the stripes at the elevation volition be and plan accordingly. 3D Hole Optical Illusion Drawing 7 Ane important detail is to make sure you end upwardly with an even number of stripes. Y'all'll meet why this is important in a infinitesimal. Once nosotros have all the stripes cartoon in, permit's erase the outer nearly circle.

Step three – Inking and Shading

Now, nosotros'll use a sharpie marking to fill in the outer circle using an alternating design. This is why information technology's important to have a fifty-fifty number of stripes. If the stripes were odd, information technology would throw the pattern out of sync. 3D Hole Optical Illusion Drawing 9 The large sharpie marker won't be able to color in the squares all the way to the border, so we'll just become every bit close to the edge equally nosotros can for now. Go on doing this for all the circles. At present, let's take a smaller pen and fill in the pocket-size gaps that we couldn't get with the larger marker. 3D Hole Optical Illusion Drawing 11 The terminal step is to create a dark gradation at the heart hole. I'll use a 9xxb graphite pencil to put in a base of operations tone. You also can employ a 4B or 6B pencil for this. And I'll apply a blending stump to smooth out the tone. 3D Hole Optical Illusion Drawing 13 And at present I'll utilize a charcoal pencil to put in a actually dark layer for the hole. And that'south it! At present all we have to practice is look at this drawing at an angle to see the 3D optical illusion.
