Very likely this is a very dumb question.
It's about computer animation or graphics (all I know is that computer animation is a type of computer graphics...I think).
But anyway my question is how would I use it in a video game if I wanted to make a more realistic game (as in like Minecraft or Valorant realistic)? I know it's vague but yeah. Dumb it down if you need too I just need the most basic idea of how it works not a lot of detail, but just enough to have a basic understanding.
