AR and VR Engineering

Definition

Multithreading is a programming technique that allows multiple threads to exist within a single process, enabling parallel execution of tasks. This method enhances performance by utilizing CPU resources more efficiently, especially in applications requiring real-time interactions or complex computations. In the context of cross-platform development, multithreading plays a crucial role in ensuring that applications run smoothly on different operating systems while managing tasks simultaneously.
