What is cone tracing?
I'm just jotting down notes on how to do things before I actually get started trying to learn how to make my own game.
I saw this eye catching thumbnail of some very cool looking grass(which I have no idea how to make) and wanted to see how he made his lighting look so good. It even has some type of redish tint from the glare of the sun. http://www.youtube.com/watch?v=jXvpjnNSnKY
So what exactly is cone tracing and how do you do it in Unity?
A lot of graphics techniques are good for off-line renders -- where you can take an hour to make a one-$$anonymous$$ute clip. Whenever someone asks "can Unity do X graphics trick?" the answer is usually:
1) it's already automatically doing it, 2) no game can ever use that trick and run fast, or rarely 3) no, they may add it in the next version, and there's no way you can add it yourself.
Cone tracing isnt something I wouldnt be concentrating on if you are just starting to make games. But if you want to learn about rendering techniques then I have linked you to a PDF that explains what cone tracing is and the maths/ concepts behind it.
