1. THE FUTURE STARTS HERE
3D Modelling – Techniques
covered in Game Art Courses

2. Each 3D model is made of three basic elements
• Vertices - individual points in 3D space that define
the corners and intersections of a mesh.
• Edges – they define the boundaries of a surface in
the 3D model
• Faces - the surface of the 3D model
All three functional elements come together to form a
3D model.

3. To manipulate the 3D model, you’ll either change,
create, alter any one or two or three of these
elements.
For Example – Turning a cube into a cuboid will
involve changing the vertices, the faces’ dimension will
change to match the vertices.

4. 3D Models can be shown on a 2D screen through a
process known as 3D rendering (much like the 3D
object on the right)
They can also be created/crafted into physical 3D
objects by 3D printers.

5. There are three main types
• Solid Modelling – involved manipulating basic
shapes such as cubes, spheres and so on.
• Wireframe Modelling – For Complex shapes, best
described as a collection of Faces, each with at
least 3 vertices
• Surface Modelling – most advanced technique,
involves using guiding lines to define shape and
curvature
All three functional elements come together to form a
3D model.
Main types of Modelling

6. There are three main types
• Boolean Process – creating complex shapes by
combining and/or subtracting existing objects
• Pick & Place – Self-explanatory
• Parametric and Procedural Modelling – Involves
using mathematical equations to define size, shape,
position etc
• Sculpting – involves adding or subtracting material
similar to traditional clay sculpting – ideal for
crafting character models

7. 3D Rendering – it is the process of showing a 3D
model on a 2D screen, done by a 3D
renderer/rendering engine.
Popular rendering engines include Blender and
Unreal Engine.
Mesh – A collection of polygons in 3D objects,
used to refer to the complexity of any 3D model
Ambient Lighting – much like in real-life,
ambient lighting is a uniform multi-directional
light that illuminates the 3D model
Must-Know 3D Modelling Jargon

8. Texture Mapping – Best explained as applying
paint/sticker/vinyl to your model
Tris & Quads – A polygon on a model with 3
sides or 4 sides, respectively
Topology – the distribution of a model’s edge
and its structure, it directly affects texturing and
animation
Rigging – Creating the 3D object’s “skeleton” so
that it can be animated – this is usually done for
characters, and props which transform in a
specific way

9. • Getting started with anything can be a daunting
task.
• To start with digital artwork, you can use a drawing
tablet or a drawing app such as Adobe Photoshop
and Procreate
It is highly recommended to begin with a rough 2D
sketch of the model you’d like to create
• Blender is a free and open-source 3D modeling
software and is supported by numerous community
resources for learning.

10. Fundamental Concepts
● Once you are comfortable with the tools, stylus,
and shape, you can move to the other level of
understanding by learning all the fundamental
concepts.
● These concepts apply to both traditional and
digital artwork. This includes concepts like forms
and structure, perspective, anatomy, composition,
values, and colours.
Learning Courses
● Choosing a beginner-level digital art course will
help you set a new path and get more
opportunities. A guided course will be far more
effective than learning on your own.
