# 3D Generation
> Convert images or text descriptions into 3D models — 5 AI models including Meshy-6, Trellis, TripoSR, and Stable Fast 3D
# 3D Generation
Convert product images or text descriptions into downloadable 3D models. Choose from 5 AI models with different speed/quality tradeoffs. Export in GLB, OBJ, or FBX format for use in 3D applications, AR/VR, or product visualization.
**Credit Cost:** 15–30 credits (model-dependent)\
**Output Formats:** GLB, OBJ, FBX\
**Access:** [app.wrldwide.ai/3d](https://app.wrldwide.ai/3d)
***
## Available Models
### Meshy-6 (Best Quality) — 30 credits
**Image-to-3D with highest quality output**
* **Input:** Product image
* **Output:** High-quality 3D mesh with texture
* **Character:** Best detail, most accurate texture mapping, production-ready
* **Speed:** Slower (best quality takes time)
* **Best for:** Final production 3D assets, hero product visualization, AR commerce
***
### Meshy-6: Text → 3D — 30 credits
**Generate 3D directly from a text description**
* **Input:** Text prompt
* **Output:** 3D model based on description
* **Character:** AI generates a complete 3D model from your words
* **Speed:** Slower
* **Best for:** Concept 3D models, ideation, when you don't have a reference image
***
### Trellis — 25 credits
**High-quality image-to-3D with strong mesh quality**
* **Input:** Product image
* **Output:** 3D mesh with texture
* **Character:** Strong mesh topology, good for complex shapes
* **Speed:** Standard
* **Best for:** Products with complex geometry
***
### TripoSR (Fast) — 15 credits
**Fastest image-to-3D model**
* **Input:** Product image
* **Output:** 3D mesh
* **Character:** Speed-optimized, good for iteration and preview
* **Speed:** Fastest of all models
* **Best for:** Quick 3D previews, iteration, testing different products
***
### Stable Fast 3D — 20 credits
**Balanced quality and speed**
* **Input:** Product image
* **Output:** 3D mesh with texture
* **Character:** Good balance of quality and generation speed
* **Speed:** Fast
* **Best for:** Most product photography use cases
***
## How to Use
Navigate to [app.wrldwide.ai/3d](https://app.wrldwide.ai/3d)
Choose based on your needs:
* **Best quality** → Meshy-6
* **No reference image** → Meshy-6 Text → 3D
* **Speed** → TripoSR
* **Balance** → Stable Fast 3D
* **Image modes:** Upload a product photo (JPG, PNG, WEBP). Ideally clean background, all product angles visible.
* **Text mode (Meshy-6 Text):** Describe the 3D object you want.
```

adjustable arm, white base
```
* **Output Format:** GLB (universal), OBJ (most compatible), FBX (Unreal/Maya)
* **Remove Background:** Toggle to automatically remove the background from the source image before processing (recommended for cleaner 3D)
* **Foreground Ratio:** Adjust how much of the image the product occupies (default 0.85)
Click **Generate**. Processing takes 1–5 minutes depending on model and complexity.
Preview the 3D model in the viewer. Download in your selected format(s). Multiple output formats can be downloaded.

| **TripoSR** | 15cr | Image | Fastest | Quick preview |
***
## Output Formats
| Format | Best For |
| ------- | --------------------------------------------------------------- |
| **GLB** | Universal — works in most 3D viewers, web AR, Shopify 3D |
| **OBJ** | Maximum compatibility — Blender, Maya, Cinema 4D, most 3D tools |
| **FBX** | Unreal Engine, Unity, Autodesk applications |

## Use Cases
### E-Commerce AR Visualization
Generate GLB 3D models of your products for Shopify's "View in AR" feature. Customers can see the product in their space before purchasing. Works directly with Shopify's 3D product viewer.
### Product Concept Visualization
Use Meshy-6 Text → 3D to generate 3D models from descriptions before manufacturing. Share 3D previews with clients or manufacturers without physical samples.
### 360° Product Showcase
Export a 3D model and use it to render 360° turntable videos from multiple angles — far cheaper than multi-angle photography setups.
### Design Review
Quickly convert product concepts into 3D for team review. TripoSR's speed makes rapid iteration practical.

## Image Quality Tips
For best 3D generation results:
* **Background:** Clean, neutral or white background allows better object extraction
* **Angle:** Capture the product from 45°–60° for good 3D reconstruction
* **Lighting:** Even lighting with minimal shadows preserves texture details
* **Resolution:** Higher resolution inputs yield better texture quality
* **Remove Background:** Use the auto-remove background toggle or [Background Removal](/en/features/background-removal) first

## Node System Integration
Use 3D generation in automated workflows:
```
[Image Upload Node] → [3D Generation Node] → [Export]
```
See [Node System](/en/features/node-system) for available 3D nodes.
