What Is 3D Modelling
                     WHAT IS 3D 
MODELLING AND 
WHAT IS IT USED 
FOR?
What is 3D modelling?
3D modelling is the process of creating three-dimensional 
representations of an object or a surface. 3D models are 
made within computer-based 3D modelling software, which 
we’ll explore a little later.

3D modelling process
During the 3D modelling process, you can determine an 
object’s size, shape, and texture. The process works with 
points, lines, and polygons to create the 3D shapes within the 
software.

How does 3D modelling work? 
A 3D model is essentially made up of vertices, which come 
together to form a mesh and act as the core of the 3D model. 
Each point on the model can be manipulated to change the 
shape.

How does 3D modelling work cont. 
y using coordinate data, the software identifies the location of each 
vertical and horizontal point, all relative to a reference point. 
The most common way to begin making a 3D model is to start with a 
basic shape – a cube, box, sphere, or whatever you think is best suited.

What is 3D modelling used for? 
Many industries utilise 3D modelling for a range of projects; 
there are likely loads of 3D modelled items we use without 
even realising its involvement. With 3D modelling, the 
opportunities are endless.

Game development
3D models are used to create characters, settings, props, and 
entire worlds within video games. The key to any good game 
is immersion, and 3D modelling is a great way to build 
immersive experiences.

3D printing
3D printing lets 3D models become physical objects which 
can be used for anything you set your mind to. It’s a lot more 
than just miniature figures and toys from at-home printers; 
there are endless useful ways to utilise 3D printing.

Architecture 
Another common use of 3D modelling is architecture. 3D modelling 
lets architects plan beyond the traditional method of hand-drawn 
building plans. As technology has evolved, we’re now able to 
conjure up a three-dimensional visual of a building before it is fully 
built.

Animation 
Once you have a 3D model, it can be completely rigged and 
animated – which comes in very handy for animation. 
Animators use 3D models for a clean, seamless effect when 
creating movies and TV shows.

Product design
Many of the products we see around us in our day-to-day lives 
would have had some 3D modelling involvement. By creating a 
virtual 3D model of your product before it is physically created, 
we can pinpoint any errors and adjust the product accordingly.
