Omni-Primitive-Transforms是一个3D对象原始变换数据集，用于生成受控单一或组合原始变换（如旋转、平移和缩放）的3D对象序列。它通过使用Blender渲染来自OmniObject3D的高质量扫描网格创建。数据集包含5,911个对象，涵盖216个日常对象类别，图像分辨率为128×128，每个对象有72个视图，每个视图对应5度增量旋转（从0°到355°，共360°），并提供了每个视图的分割掩码，以支持通过2D变换合成缩放和平移等操作。这些特性使得数据集能够直接支持真实的3D旋转变换，并允许合成额外的2D变换，无需重新渲染。Omni-Primitive-Transforms is a 3D object primitive-transformation dataset used to generate 3D object sequences under controlled single or compositional primitive transformations—such as rotation, translation, and scaling—by rendering high-quality scanned meshes from OmniObject3D with Blender. The dataset includes 5,911 objects across 216 everyday object categories, with an image resolution of 128×128. Each object has 72 views, corresponding to rotations in 5° increments around the vertical axis (from 0° to 355°, covering a full 360°), and provides segmentation masks per view to enable synthesis of additional 2D transformations (e.g., scaling and translation) without re-rendering. This allows for true 3D rotation transformations and the composition of combined sequences.
