Hi

I'm currently working on a new project. This will be an interactive game (using kinect) where the main protagonist (you) will be playing accompagned by 2 real actors filmed and blended (using green chromakeying) in a 3D rendered environnement. The player will have to execute series of actions to complete the quests.

The player is not really evolving freely in the 3D space. When moving, he will only follow predetermined paths (like crossing a bridge). The player will be interacting with the environnement (like destroying obstacles) but always in the same manner.

I think that it might not be efficient to use a classic 3D game engine for this application, because I will have to deal with complex environnement meshes, shaders and effects, even if the player is not freely evolving in the environnement.

So I was more thinking about creating my game with layers of small video sequences. For example : The environnement is a back layer with a cyclic prerendered sequence of the environnement, and the obstacle is a front layer sequence in pause status, waiting for the player to perform the correct action to play its "destroying" prerendered sequence.

Doing so, I hope to be able to spend less time on the game development by letting my graphist focusing on "top-quality prerendered sequences".

Questions :

• Do you know a project that already used the same principle ?

• Does a game engine exists (preferably open-source) for this type of game ?

• What library (preferably C++ or Java) could I use to play (forward and reverse) multiple layers of video sequences ? (OpenCV seems to have problems playing backwards...)

I am fully opened to any remark, suggestion or answer ! Thanks !
