1. Photo Capture & Framing
- Even, Diffuse Lighting: Avoid direct harsh sunlight or single-point flash. Diffused ambient light prevents baked-in shadow artifacts.
- Multiple Angles: For best results, capture primary front, back, 3/4 quarter view, and top-down angles.
- Focal Length: Use a standard 50mm equivalent lens to avoid wide-angle barrel distortion.
2. Background Removal & Pre-processing
- Isolate the subject with transparent alpha or solid neutral gray (RGB 128,128,128) background.
- Crop tightly around the bounding box of the object to maximize the AI model's spatial resolution.
3. Material & Scale Estimation
- Indicate matte vs. reflective surfaces. For metallic objects, prompt assistance (e.g. "polished chrome") ensures correct metallic map generation.
- Declare physical scale (e.g. 15cm height for tabletop figurine vs. 2m for furniture).
4. Mesh Cleanup, Retopology & UVs
- Check for manifold watertight geometry (especially crucial for 3D printing).
- Run automated quad remeshing (Instant Meshes or Quad Remesher) if animating in Maya/Blender.
5. PBR Shading & Normal Baking
- Verify standard Roughness/Metallic workflow.
- Ensure Ambient Occlusion (AO) is baked into the texture set for realistic depth shading.
6. Export Formats & Engine Validation
- Web/AR: GLB / USDZ (under 15MB for fast mobile loading).
- Game Engines: FBX or GLTF with embedded material textures.
7. Frequently Asked Questions
Can I convert a single 2D image into 3D?
Yes, Next3D uses state-of-the-art single-image reconstruction to hallucinate missing back-surface geometry and textures automatically.
Can I use photos taken on my smartphone?
Yes. Modern smartphones produce sharp, high-resolution photos that work excellently for AI 3D model generation.
