Metal

Definition

In the context of content creation tools and software, metal refers to a type of graphics API (Application Programming Interface) that provides low-level access to the GPU (Graphics Processing Unit). This allows developers to create high-performance applications, particularly in immersive and virtual reality environments, by optimizing rendering processes and improving overall graphics quality. Metal is significant because it helps bridge the gap between hardware capabilities and software performance, enabling more dynamic and realistic visual experiences.
