autoRotateSpeed

autoRotateSpeed is a property found in various 3D graphics and game development contexts, particularly within libraries and engines that handle 3D object manipulation. It dictates how quickly an object automatically rotates around a specified axis or axes. This property is typically a numerical value, often represented as a floating-point number, which determines the speed of rotation in degrees per second or radians per second.

When autoRotateSpeed is set to a non-zero value, the object will continuously rotate. A positive value usually indicates rotation in one direction, while a negative value signifies rotation in the opposite direction. The magnitude of the value directly correlates to the speed of this rotation. For instance, a higher autoRotateSpeed will result in a faster spin.

This feature is commonly used for visual effects, such as spinning promotional items in a product showcase, creating dynamic backgrounds, or animating elements in a user interface. Developers can control the rotation on specific axes (like X, Y, or Z) by adjusting individual rotation speed properties if they are available, or by applying a vector to define the rotation direction and speed. The ability to dynamically change autoRotateSpeed allows for interactive or time-based animations, adding life and movement to 3D scenes. Setting autoRotateSpeed to zero typically disables the automatic rotation.
