Magpie：互動式遊戲的即時世界渲染器

摘要

現代遊戲開發高度依賴傳統圖形管線。高品質的視覺內容需要建模、材質製作、動畫、光影、特效及執行期最佳化，使得美術資產的生產成本高昂，並延長了遊戲原型的開發週期。近年來，影片基礎模型開始改變電影與影片的製作方式，但遊戲不同於線性媒體，它不僅需要連續且逼真的影像，更需要穩定且可重現的遊戲規則、物體狀態與互動結果。我們提出 Magpie，一個適用於互動式遊戲的即時生成式世界渲染系統。Magpie 將遊戲邏輯執行與視覺生成分離。設計者在遊戲引擎中定義場景與規則。在執行期間，遊戲引擎解析玩家動作並維護世界狀態，而獨立的渲染伺服器則根據引擎產出的白盒框架生成視覺輸出。Magpie 為將生成式模型應用於即時遊戲渲染提供了系統層級的實作路徑。它保留了遊戲玩法的可設計性與可重現性，並降低了早期遊戲原型對完整視覺資產的依賴。

Modern game development relies heavily on conventional graphics pipelines. High-quality visual content requires modeling, material authoring, animation, lighting, effects, and runtime optimization, making asset production expensive and extending the development cycle of game prototypes. Recently, video foundation models are beginning to change film and video production, but games differ from linear media, they require not only continuous and realistic imagery, but also stable and reproducible gameplay rules, object states, and interaction outcomes. We present Magpie, a real-time generative world-rendering system for interactive games. Magpie separates gameplay execution from visual generation. Designers define scenes and rules in a game engine. At runtime, the Game Engine resolves player actions and maintains world state, while an independent Render Server generates visual output from white-box frames produced by the engine. Magpie provides a system-level implementation path for applying generative models to real-time game rendering. It preserves gameplay designability and reproducibility, and reduces the dependence of early game prototypes on complete visual assets.
