3d model movement

Rodimus · 2011-07-07T22:19:11

How do games normally do it when 3d models move or/and rotate? Is it an animation or does it actually move and rotate through code? I started wondering about this while playing Dungeon Siege III yesterday. There's a place in the game where you are running over a floating pathway and hovering rocks move in circles around the path. Here's an image that I hope will make it a bit more clear.

What I am trying to describe is movement that involves movement of the object in its environment and not "internal movement" in the object (Like a flag in wind or a car engine shaking). If both methods are used, what are the pros and cons with them? I don't know if it's possible to answer this, but I got a bit curious and thought maybe someone here knows. If this is the wrong forum to post this, please move it.

After reading the other guys post I realized your specifically talking about moving terrain stuff. What I would do with my engine is:

1.) Model the moving platform.
2.) Idle animation is rotating about its center point.
3.) Attach the platform to a 3D waypoint system that is basically a circle or whatever around the main center stage platform that is in the middle. This way everything works relative to itself and is not overriding positions from the wrong spot.
