What are the products of rendering?

Could you please elaborate on the products of rendering? I'm particularly interested in understanding what exactly is produced through this process. Is it a physical object, or perhaps a digital representation? Are there multiple types of products that can be derived from rendering? Could you provide some examples of these products and explain their uses and applications? Additionally, I'm curious about the industries or fields where rendering is commonly used and how the products it generates contribute to these industries. I'm eager to gain a deeper understanding of this topic, and your insights would be greatly appreciated.
