The wiki is now hosted by GameDev.NET at wiki.gamedev.net. All gpwiki.org content has been moved to the new server. However, the GPWiki forums are still active! Come say hello. [edit] Uses of interpolationIt would be useful if the tutorial told us *how* linear interpolation is used in animation. Nothing too fancy, just a basic description. --IGTHORN 09:02, 23 Sep 2005 (EDT) [edit] Use of Linear InterpolationIt's commonly used with motion in general. Example: There is an object which moves from point A to point B. In code you store the new position as B and the old position as A. But when you draw it you don't want your object to jump from A to B, instead you want it to gradually make its way there (motion). To do this you apply the linear interpolation equation: Draw_Position = Last_Position + Percent * (New_Position - Last_Position) Where Percent is how far conceptually you are into the next game logic tick. See [1] for more information. --sdw 15:26, 23 Sep 2005 (EDT) |
