3D scale, rotation, and transformation

The next thing we need to understand is how to apply scale, rotation, and transformation to an object and thus solve the problems we identified. Without getting deep into the math, let's just understand what those terms mean:

• Scale: It allows us to define how large or small an object is. In our example, our object is too big and thus we need to scale the object down. We will learn how to do that shortly.
• Rotation: It defines how an object is orientated or posed. We will use both terms interchangeably. Rotation is a bit more complex, and we won't worry about it for this example.
• Transformation: It defines the position of an object, where a position of 0,0,0 represents the origin. In our example, we want ...
