The Basics of 3D Rotation
In 3D design, rotation means turning an object around its centre or a specific point. It is a fundamental transformation operation that changes an object’s orientation.
Definition of Rotation
Rotation is the movement of an object around an axis or point in space. Rotation is important for positioning and animating objects in 3D space. It can be described using degrees or radians.
Euler Angles vs. Quaternions
There are two ways to represent rotations in 3D space: Euler angles and quaternions. Euler angles have 3 angles to describe rotation, quaternions use a 4-element structure.
Degrees vs. Radians
Rotations can be measured in degrees or radians. Degrees are common for simple changes, radians are used in complex math operations.
3D Coordinates and Axes
To understand 3D rotation, you need to grasp the concept of 3D coordinates and axes.
Cartesian coordinates are a system that uses three perpendicular axes (X, Y, and Z) to locate a point in 3D space. This system is the foundation for most 3D modelling and design work.
X, Y, and Z Axes
The X, Y, and Z axes represent the three dimensions in 3D space. They determine the direction and magnitude of a rotation.
How Rotation Affects Coordinates
When an object rotates, its position in 3D space changes, and this, in turn, affects its coordinates. Understanding this relationship is key to successful 3D design.
Types of 3D Rotations
Rotations in 3D space have different forms based on the transformation nature.
Rotation About a Single-Axis
This is the simplest form of rotation, where an object pivots around one axis. It’s akin to turning a book on a shelf.
Combining Rotations
Complex 3D designs often involve a combination of rotations around different axes. Understanding how to combine these rotations is crucial.
Interpolation in 3D Rotation
Interpolation is the process of generating intermediate rotations between two keyframes. It ensures smooth and realistic animations.
