What are Transformations
In the last chapter, we learned about animations, where we moved a single point in a specific direction.
But what if we want to move an entire triangle, rotate it, or apply other changes that modify its vertices?
This is where transformation matrices come in. They provide a powerful and elegant way to manipulate objects in computer graphics. Let’s dive in and understand them in detail.
Matrices
I hope you are familiar with matrices and basic operations like addition, subtraction, and multiplication.
Keeping my promise to explain every bit of math except for the simplest operations, let's take a brief look at matrices and how they are useful in computer graphics.
A matrix (singular of matrices) can be seen as a 2D array of numbers that has a fixed number of rows and columns.
Example Matrix (3×3):
