// how it works
How it works
- Give it a prompt
Describe the object or scene — some tools also accept a photo.
- Generate the model
The AI builds geometry, and often textures or materials too.
- Inspect and refine
Rotate, fix proportions, and polish the result before export.
- Export the asset
Save as GLB, OBJ, or another standard format for your pipeline.
// features
Why people love it
Text-to-3D
Turns written descriptions into 3D geometry.
Image-to-3D
Reconstructs models from one or more photos where supported.
Textured output
Generates materials and textures, not just bare meshes.
Standard exports
Saves to GLB, OBJ, and other formats your tools accept.
Editable results
Outputs you can refine instead of black-box meshes.
Local pipelines
Many workflows run on your own GPU with open models.

// run it
Run it yourself
- Step 1 — Clone the repo
Download the source and move into the project folder.
git clone https://github.com/ziplab/Block3D.git cd Block3D - Step 2 — Check the README
Every project documents its own setup; start with install requirements.
cat README.md | head -60 - Step 3 — Run it
Follow the project’s launch command — Docker, pip, npm, or a binary release.
# see README for the exact launch command
// use cases
What you can build
- Generate 3D from text efficiently.

Questions, answered
What can I do with the models?
Use them in games, renders, AR, or 3D printing — exports are standard formats.
What license is it under?
It uses a custom license — read the LICENSE file in the repo before using it commercially.
Do I need a GPU?
Yes for local generation — 3D models are heavy. Cloud options exist for lighter machines.
How good is the quality?
Good for prototyping, concepting, and stylized work; hero assets still need artist polish.
How active is development?
Last pushed 2026-08-25 with 4 forks. Check recent commits for momentum.
