Frequently Asked Questions

Image3D AI FAQ

What image formats and quality work best for conversion?

For optimal results, upload high-contrast images (PNG, JPEG, or WEBP) with clear, well-defined outlines and a simple, uncluttered background. The subject should be in focus with good lighting. Avoid blurry, dark, or overly complex images where the main object is obscured. Following these best practices dramatically increases the AI's ability to accurately interpret shape and depth.

What is the difference between Single Image and Multi-view modes?

Single Image mode (Rapid) uses AI inference to generate a 3D model from one picture, ideal for logos, sketches, or objects with an obvious shape. Multi-view mode (Pro) requires several photos of a real-world object from different angles. This provides the AI with more geometric data, leading to a physically accurate and higher-fidelity reconstruction, which is essential for precise 3D printing or detailed digital twins.

Which output file format should I choose?

The choice depends on your intended use. Select .STL if you plan to 3D print the model. Choose .OBJ if you intend to edit the model further in traditional 3D software like Blender, 3ds Max, or ZBrush. Opt for .GLB if you need the model for web display, AR/VR applications, or game engines, as it is a compact, modern format that includes textures and materials in a single file.
