Rotational Axis
Overview
A rotational axis is an imaginary line around which an object rotates. When an object rotates, its points move along the rotational axis. The rotational axis is perpendicular to the plane of rotation.
The rotational axis is a critical concept in computer graphics because it is used to define the orientation of objects in 3D space. The rotational axis is also used to calculate the rotation of objects, such as when a character turns their head or a car turns a corner.
Here are some of the benefits of using a rotational axis:
-
Simple: A rotational axis is a simple concept that is easy to understand and implement.
-
Flexible: A rotational axis can be used to rotate objects in a variety of ways.
-
Efficient: A rotational axis can be implemented efficiently, which makes it ideal for use in real-time applications.
Here are some of the drawbacks of using a rotational axis:
-
Can be disorienting: If the rotational axis is not aligned with the user’s perspective, it can make objects appear disorienting or unnatural.
-
Can be difficult to control: The rotational axis can be difficult to control, especially in complex scenes.
-
May not be suitable for all applications: A rotational axis may not be suitable for all applications, such as flight simulators or racing games.
Overall, a rotational axis is a powerful and versatile concept that is used to define the orientation of objects in 3D space and calculate the rotation of objects. However, it is important to be aware of its potential drawbacks, such as its ability to disorient the user and its difficulty in controlling.
