tengelyszög
A tengelyszög, or axis angle, is a way to represent the rotation of a rigid body in three-dimensional space. It is defined by two components: a unit vector representing the axis of rotation and a scalar value representing the angle of rotation around that axis. Imagine a line passing through the center of an object. This line is the axis of rotation. The tengelyszög specifies how much the object spins around this line and in what direction.
The unit vector indicates the direction of the axis. For example, if the axis of rotation is
The tengelyszög representation is often used in computer graphics, robotics, and physics to describe the orientation
