How To Draw 3d Shapes
In this lesson, nosotros're going to focus on how to give our sketches a 3 dimensional quality.
At the end of this lesson, we're going to revisit our homework assignments from the previous 2 lessons and apply the techniques from lesson three. If you oasis't read and applied what you learned in lesson one and 2, I encourage you to visit them before y'all read on.
Lesson 1: How to Sketch
Lesson two: Acquire to See Things Differently
When cartoon something realistically, we're depicting what a 3D object will look similar on newspaper. In reality, the objects fatigued are actually 2D because they have no physical depth.
How in the world can we draw something that looks 3D, while in reality being flat on the folio?
What Makes Drawings Wait 3D?
Many factors contribute to this. I'm just roofing a few in this lesson and will sprinkle more in the following lessons.
Planes
The image below shows y'all 2D objects beingness transformed into 3D. I added some shading for you to visualize information technology better.
The reason why these objects look 3D is because I've given them additional faces. Each face is called a plane and each aeroplane is facing a different direction. Multiple planes on ane object give the illusion of depth. Y'all can at present imagine each object having book.
It'due south easy to describe 3D objects when they have obvious vertices or difficult edges, simply what about weird shapes like circles, blobs, or even people? How practise you define the planes/faces on a round object? That's where profile lines come in.
Contour Lines
The beginning row of objects below appear completely flat. You could say they each take i confront.
In the 2d row, the objects accept lines wrapped effectually them which make you lot visualize their many sides. These lines are chosen profile lines because they follow the form of the object. Contour lines tin can run in any direction along the surface of an object to help you create the illusion of form, giving the object a more than meaningful shape.
When to Use Contour Lines
Here are some examples of when you tin can make use of contour lines.
Cartoon Faces:
If you're drawing a character whose face up is tilted, contour lines will act as guidelines to aid you find out where to place features on the face, such as where to draw the eyes, olfactory organ and oral cavity. Notice how the eyes on the cat in the second row wrap around the face more naturally. The olfactory organ and oral fissure are besides aligned properly down the center of the confront compared to the kickoff cat.
Here'south a more than obvious example – a animal with 6 eyes:
Use your imagination to think of where you lot can make employ of this technique. Maybe a belt around Santa's large tum, a band effectually a finger or a headband around someone'southward head.
Defining Surfaces
Contour lines tin can be used to accentuate curves. Find how the lines used in the examples beneath brand a large deviation in how the subject is perceived: Full lips versus flat lips. The more curved my lines are, the more than plump the lips appear to exist.
Hither's an case of a flower. When you wait at the flower on the right, the stripes of each petal are curved. The curves follow the shape of each petal.
When Should You Draw in 3D?
The short reply is: whenever possible.
First of all, whether you're drawing a transparent or opaque object, y'all'll want to arroyo information technology the aforementioned way. As a beginner, it's ever a practiced thought to draw all sides of the object. This practise volition help you improve accuracy, so you tin can draw objects that brand more than sense.
Using the toy auto example beneath, drawing the entire object in 3D helps me know where to describe each wheel instead of guessing where they should get.
How to Depict in 3D
Since this lesson is an introduction to 3D, I want you to focus on only a few things to begin with.
Cartoon Objects with Vertices and Difficult Edges
This is the quick and simple method considering it doesn't business relationship for perspective (something I will comprehend in lesson 6):
Steps: Depict a simple shape with corners, indistinguishable that shape, draw lines to connect the vertices together and then shade the object.
Tip: If you lot draw your second shape lighter than the first, it will appear further abroad.
For shapes with round edges, draw your connecting lines at the outer-about edges. If you lot size your shapes differently like the example beneath, it volition give your drawing an added layer of depth. Even so, equally mentioned above, this freehand method is quick simply not very accurate compared to what nosotros'll be learning in lesson 6.
For cylindrical shapes similar cups, jars, pop cans and vases, you lot can use the method below: Draw your 2nd object and then add together ellipses to the top, bottom and/or sides.
By changing the bore of your ellipses, you lot can tilt your cylindrical shape more or less, every bit illustrated in the example beneath:
This thought can also be applied to drawing faces. You can change the direction you want your subject to face by changing the bore of each ellipse or ring.
In the epitome below, assume that the sphere in the center is facing straight towards yous. The point at which the 2 rings cross is the very front end of the sphere.
As you lot look to the left, each sphere starts facing more towards the left side. The reverse applies to the right side. If you want a graphic symbol to look up or down, you can apply the aforementioned idea to the horizontal ring.
Drawing Irregular Objects
Contour lines help y'all turn irregular 2D shapes into 3D. You tin influence the fashion a viewer perceives your drawing by manipulating its contour lines. Nevertheless, this procedure comes with some exercise. If your contour lines exercise non accurately represent the shape you lot are drawing, for instance, a sphere, your viewer will not perceive a sphere.
Here'south an instance of how contour lines tin can manipulate your perception. I've shaded each object to improve illustrate what I mean. Contour lines + shading make a powerful pair!
Tip: If your lines bend near the edge of your object, it makes the viewer think there is more on the other side, which magically lifts the object off the page.
A sphere, if observed from whatever side, has the outline of a circle shape. And so if you desire to draw a sphere, utilise various ellipses as profile lines.
A series of narrow rings volition give you a pebble-similar class, while a serial of wide rings will requite you lot a wider, rounder course. Hither are some examples of what I hateful. For each shape beneath, I'm showing you the forepart of the shape and the side view.
No affair what shape it is that yous want to add contour lines to, e'er visualize it from different angles so you tin create contour lines that best describe the form.
The power to draw good contour lines takes a lot of visualization and practise. Once you understand information technology, it'll be one of the greatest tools in your toolkit!
Summary of the Above
In brusque:
- You tin make things look 3D by indicating that your subject has multiple planes.
- Use contour lines for irregular objects like circles, blobs, etc.
- Always sketch in 3D. Your final drawings will await more authentic.
- To draw a 3D object with vertices: describe ane shape, indistinguishable it, connect the vertices and so shade it.
- To depict irregular shapes such equally spheres or blobs: apply a series of contour rings.
Your Homework for the Week
Your assignment for the week is to accept a expect at your drawings from lessons 1-2 and recreate as many drawings in 3D or incorporate contour lines in them if you haven't done that already. I'll be submitting my left-handed homework to facebook. You're welcome to share your homework on there also :)
A great style to practice drawing contour lines is to grab a paper, mag or a few pictures off the net and describe over them! If you want more than examples, head over to Google Images and search for "object wireframe" or "animal wireframe" etc and report the images. You tin can use them as reference while you practice drawing contour lines.
If yous desire to effort a more difficult exercise, cheque out these absurd pictures here. Try creating forms using merely profile lines. Here's a elementary tutorial you tin utilise to depict a hand: http://www.handimania.com/diy/3d-handprint.html
This week'due south challenge: Turn xv 2d objects into 3D sketches. These objects can exist anything from apples, chairs, milk cartons to low-cal bulbs. Submit your drawings to the RFA Facebook folio and I'll feature your artwork beneath! Each transformation must have a 2D cavalcade and 3D column similar to the example below:
Have fun!
