🧱 Step-by-Step: Convert Picture to 3D Model

✅ Step 1: Understand Your Image Type

What kind of image do you have?

• Face / Portrait photo → Use AI face-to-3D tools

• Product / Object photo → Use photogrammetry or AI object-to-3D tools

• Logo / Drawing / Silhouette → Can be extruded into 3D using tools like Blender or Tinkercad

---

🛠️ Methods Based on Image Type

🧍 1. Face Photo → 3D Face Model

Use AI tools like:

• Meshroom (Open-source) – Photogrammetry if you have many angles

• 3Dthis – Online face generator

• Avatarify.ai

• [Lumirithmic, DeepFaceLab, or Ready Player Me] – Realistic face modeling

Output: .obj, .glb, .fbx 3D model files

---

📦 2. Single Object Photo → 3D Model (AI-based)

Tools that convert single photos into 3D objects:

• Kaedim – AI to generate 3D from concept art

• Luma AI – Works best with video or multiple angles

• Spline AI – Good for simple product shapes

• [GET3D by NVIDIA (Advanced)**] – AI trained to infer 3D shapes from 2D

🎨 3. Sketch / Logo → 3D Extrude

If your image is a flat drawing, you can:

1. Convert image to SVG (vector)

2. Import to Blender, Fusion 360, or Tinkercad

3. Extrude it into 3D

4. Export as .obj or .stl

Free tool to convert to SVG:

💾 Output File Types (for Mesh Upload or 3D Printing)

Format	Use Case
.obj	Common 3D model format
.glb / .gltf	Web-friendly 3D model
.stl	Used in 3D printing
.fbx	Used in animation/game

---

🧪 Example Workflow (for a Face)

1. Upload your face photo to Avatarify.ai or Ready Player Me.

2. Customize avatar.

3. Download .glb or .fbx file.

4. Upload to your 3D platform (like Mesh, Blender, or game engine).
