## AI 摘要

PhotoFlow是一个用于闭环相机搜索的Director-Reviewer-Reflector智能体系统，能在预制3D场景中自主推断合适的摄影角度并生成最终图像。该系统包含VPhotoBench基准测试，涵盖47个Blender场景和141个基于语言的摄影任务。实验表明，在六轮渲染预算的设置下，PhotoFlow在多种基线方法中取得了最强的外部质量对齐表现和成功率。这是首个将基于语言的虚拟摄影转化为可执行智能体任务的工作，展示了以LLM为核心的智能体在同时涉及3D推理与美学判断的设置中，已能生成高质量摄影作品。

Virtual photography asks an agent to enter a prepared 3D scene with no preselected camera pose or reference image, infer a suitable shot from scene information and a language intent, choose executable camera parameters, and render the final photograph. Recent progress in vision-language models makes this kind of spatial agent increasingly plausible, but the task stresses two capabilities that remain hard to evaluate together: complex 3D spatial understanding and abstract aesthetic judgment. We introduce PhotoFlow, a Director-Reviewer-Reflector agent for closed-loop camera search. The Director builds a soft photographic blueprint and proposes diverse candidate cameras; the Reviewer combines rule checks, visual critique, and pairwise incumbent selection; and the Reflector converts failures into region memory, dead-zone suppression, and high-explore relocation. We also introduce VPhotoBench, a benchmark of 47 open-license Blender scenes and 141 language-conditioned photography missions spanning subject placement, relational composition, and atmosphere/style. On held-out experiments, PhotoFlow achieves the strongest external quality-alignment composite and success rate among one-shot prediction, single-chain reflection, anchor-bank selection, and random search under a six-round rendering budget. To our knowledge, this is the first work to make language-conditioned virtual photography in arbitrary Blender scenes an executable agent task, and our results show that an LLM-centered spatial agent can already produce strong photographs in a setting designed to challenge both 3D reasoning and aesthetic choice.
