图像生成用RL已经打出了漂亮的成绩单，那3D生成呢？ 当GRPO让大模型在数学、代码推理上实现质变，研究团队率先给出答案——首个将强化学习系统性引入文本到3D自回归生成的研究正式诞生，并被 CVPR 2026接收。该研究不只是简单移植2D经验，而是针对3D生成的独特挑战，从奖励设计、算法选择、评测基准到训练范式，做了一套完整的系统性 探索。 核心矛盾在于：3D对象没有「标准视角」。一张图对不对，人一眼就能看出来；但一个3D物体，需要从多个视角同时评估几何一致性、纹理质感与语义 对齐——任何一个维度设计不当，训练就会崩。 更深层的问题是，3D生成模型在自回归解码时，每一个token都携带着对整体结构的隐式承诺。这种长程依赖让奖励信号的稀疏性问题在3D中比2D更加突 出——模型很难在中途感知到哪里出了问题。 研究团队将这个问题拆成四个维度系统研究： 奖励模型怎么设计——哪类奖励信号对3D生成最有效？ RL算法怎么选——GRPO的哪些变体适合3D的序列特性？ 为什么3D比2D难得多？ RL在文本、图像生成上屡试不爽，但直接搬到3D行不通。 最出人意料的发现：通用大模型（Qwen2.5-VL）评估3D一致性，比专用模 ...
