WebJun 15, 2024 · $\begingroup$ Like I said, the you are referring to the core idea of casting rays which was known as ray-casting when Appel used it. Ray-tracing got popular because of the whole algorithm of Turner whitted to produce photorealistic images. So when you say ray-tracing, you aren't talking about just casting rays generally.
