📝 摘要(中文)

视频世界模型在生成可控视觉体验方面取得了快速进展,但大多数模型仍然从单一观察者的角度进行模拟。将这些模型扩展到多个代理面临一个核心挑战:如果每个代理的未来状态独立生成,重叠视图可能会在同一场景中实例化不同版本,导致对象、布局和外观的不一致。本文提出Prisma-World,一个可控的多代理世界模型,将多代理生成形式化为一个联合几何感知去噪过程,以实现跨视图一致性。Prisma-World在一个全注意力序列中处理所有代理视频,采用多代理RoPE设计区分代理身份,同时保持同步的时间坐标,并将相对相机几何信息注入注意力中,以引导重叠视点朝向共享场景证据。实验表明,单个Prisma-World模型能够生成高保真度的多代理视频,具备灵活的代理数量、相机可控性、改善的跨视图一致性和在小地图指导下的空间定位能力。

🔬 方法详解

问题定义:本文旨在解决多代理视频生成中的视图一致性问题。现有方法在处理多个代理时,容易导致重叠视图生成不同版本的同一场景,造成不一致性。

核心思路:Prisma-World提出了一种联合几何感知去噪的生成方式,通过全注意力机制处理所有代理视频,确保生成的视图在共享场景几何下保持一致性。

技术框架:该框架包括多个模块:首先,使用全注意力序列处理所有代理视频;其次,采用多代理RoPE设计区分代理身份;最后,将相对相机几何信息注入注意力机制,以引导重叠视点。

关键创新:Prisma-World的核心创新在于其联合几何感知去噪过程,显著改善了多代理生成中的视图一致性,这是与传统方法的本质区别。

关键设计:在设计中,采用了重叠衰减的课程训练范式和小地图条件结构指导,以增强多视图一致性和全局空间感知。

📄 摘要(原文)

Video world models have made rapid progress in generating controllable visual experiences, but most of them still simulate the world from a single observer. Extending such models to multiple agents raises a central challenge: if each agent's future state is generated independently, overlapping views may instantiate different versions of the same scene, leading to inconsistent objects, layouts, and appearances across agents. Conventional camera conditioning controls individual trajectories, but it does not explicitly couple the generation of views that should agree under shared scene geometry. We introduce Prisma-World, a camera-controllable multi-agent world model that formulates multi-agent generation as a joint geometry-aware denoising process for cross-view consistency. Prisma-World processes all agent videos within one full-attention sequence, uses a multi-agent RoPE design to distinguish agent identities while preserving synchronized temporal coordinates, and injects relative camera geometry into attention to bias overlapping viewpoints toward shared scene evidence. To further strengthen multi-view consistency and enhance global spatial perception, we augment our framework with an overlap-decaying curriculum training paradigm alongside minimap-conditioned structural guidance. To facilitate the training and evaluation of multi-agent models, we introduce PrismaDataset, a large-scale UE5 dataset with panoramic acquisition across diverse scenes, composable multi-agent view groups with flexible agent counts and complex camera trajectories, and precise camera/action annotations for consistency training and evaluation. Experiments show that a single Prisma-World model can generate high-fidelity multi-agent videos with flexible agent numbers, camera controllability, improved cross-view consistency, and spatial grounding under minimap guidance.
