I've been hunting around the internet for a while now, and I can't find anything about the specific shadow technique that I'm looking for.
I can only recall one game in particular that used it, and I know that it happens on the PC port of the game too. The game in question is "Sonic Adventure 2: Battle" for GameCube. I remember it happening on "Super Mario Sunshine", but I could be mistaken.
- The shadows are only cast from the main player character.
- It is 100% sharp, no matter the resolution the game is rendered at.
- They are cast perfectly parallel down onto the surface the player stands on.
- Interestingly, if the shadow intersects with a vertical wall, the shadow is drawn all the way up the wall, even higher than the original intersection.
- You can also see the shadow on ceilings directly above the player character, and even on floors above ceilings. It's as if there's a big character-silhouette shaped tube being cast onto surfaces.
How does this technique work, and how can I learn more about it?
I'm going to hunt for a picture of this particular technique, but I don't have one right now.
