Batch3D

Create Batch3D/b3d-compatible visualization artifacts only when the user explicitly mentions Batch3D or b3d for previewing, visualizing, saving a Batch3D-viewable file, or writing a Batch3D/b3d executable script. Use the save-file route when the user asks to save a visualization file or write a script that saves a visualization file. Use the API-script route when the user asks to use the Batch3D/b3d API, make an executable Batch3D/b3d script, interact with b3d.add/addObj/updateObj/rm, camera controls, UI, or other runtime APIs. Do not use for generic 3D visualization, mesh export, pickle/numpy saving, camera math, or point-cloud tasks unless Batch3D or b3d is explicitly mentioned. Includes a bundled b3d.pyi API reference for exact Batch3D script APIs. Also use for Chinese requests such as 帮我使用b3d可视化.
