3D images (or graphics) are effectively displayed across multiple displays provided in a gaming environment based on a 3D imaging (or graphics) model (or world). A game scene for a game played on a gaming machine is effectively displayed as a larger 3D scene across multiple displays configured for multiple gaming machines when a gaming criteria, event or condition is met (e.g., when a slot game generates a particular outcome on a gaming machine, a 3D scene is displayed on multiple gaming machines). 3D images (or objects) effectively displayed across multiple displays configured for multiple gaming machines can effect and/or complement the game being played on one or more of the gaming machines and/or used as an independent game. Animation (or movement) of one or more 3D objects can be used to trigger a gaming criteria, event or condition (e.g., start a bonus period for a game being played in a gaming machine). The gaming criteria, event or condition can be triggered solely based on the animation (or movement) of the 3D object(s) or in a combination with another condition.
