Can my AI agent convert STL to B3D?
Yes. Install the Filestar CLI with npm install -g filestar and your agent can run filestarcli -i file.stl -c "convert to b3d" on your computer, so your files stay on it.
Stl is the standard 3D data transmission file format mainly used for 3D printing. STL contains surface geometry descriptions of 3D objects and it uses a series of triangles to describe the surface geometry of a 3D model.
B3D files are 3D models created with the Blitz3D game development engine. They store the model's geometry, textures, and shading information. B3D models can be used in games, 3D animation, and other 3D applications.
