The Science of Avalanches in the New SSX

[Predetermined events] are our complete and total anti-vision... Trying to do that over hundreds and hundreds of levels is incredibly time-consuming. When you script the "who thing" the first time through it's like, 'Whoa, that was amazing', but it doesn't offer any replayability. What we've been looking at is how do we create systems that can span any level?

We looked at our snow spray model and said, 'If we start to spawn some physics particles every time you carve, and we throw those particles out loose into the world, and then we analyze the terrain that those particles are running over, and if they go over something really steep that's inherently unstable, it would actually spawn more physics particles. And if it went into an area that was flat and very stable, those particles would die out.' Just the way that snow really [works] on a mountain. Now all of a sudden just by virtue of carving through snow, you're sending out particles that start to follow the mountain and can build and grow and sink. It's insane... it's going to be a remarkable feature.
