EmbodiedGen: Towards a Generative 3D World Engine for Embodied Intelligence

EmbodiedGen is a generative engine to create diverse and interactive 3D worlds composed of high-quality 3D assets(mesh & 3DGS) with plausible physics, leveraging generative AI to address the challenges of generalization in embodied intelligence related research. It composed of six key modules: Image-to-3D, Text-to-3D, Texture Generation, Articulated Object Generation, Scene Generation and Layout Generation.

• ⚙️ Articulated Object Generation
• 🏞️ Layout(Interactive 3D Worlds) Generation

🚀 Quick Start

✅ Setup Environment

git clone https://github.com/HorizonRobotics/EmbodiedGen.git
cd EmbodiedGen
git checkout v0.1.0
git submodule update --init --recursive --progress
conda create -n embodiedgen python=3.10.13 -y
conda activate embodiedgen
bash install.sh

✅ Setup GPT Agent

Update the API key in file: embodied_gen/utils/gpt_config.yaml.

You can choose between two backends for the GPT agent:

• gpt-4o (Recommended) – Use this if you have access to Azure OpenAI.
• qwen2.5-vl – An alternative with free usage via OpenRouter, apply a free key here and update api_key in embodied_gen/utils/gpt_config.yaml (50 free requests per day)

🖼️ Image-to-3D

Generate physically plausible 3D asset URDF from single input image, offering high-quality support for digital twin systems.

☁️ Service

Run the image-to-3D generation service locally. Models downloaded automatically on first run, please be patient.

# Run in foreground
python apps/image_to_3d.py
# Or run in the background
CUDA_VISIBLE_DEVICES=0 nohup python apps/image_to_3d.py > /dev/null 2>&1 &

⚡ API

Generate physically plausible 3D assets from image input via the command-line API.

python3 embodied_gen/scripts/imageto3d.py \
    --image_path apps/assets/example_image/sample_04.jpg apps/assets/example_image/sample_19.jpg \
    --output_root outputs/imageto3d

# See result(.urdf/mesh.obj/mesh.glb/gs.ply) in ${output_root}/sample_xx/result

---

📝 Text-to-3D

Create 3D assets from text descriptions for a wide range of geometry and styles.

☁️ Service

Deploy the text-to-3D generation service locally.

Text-to-image based on the Kolors model, supporting Chinese and English prompts. Models downloaded automatically on first run, see download_kolors_weights, please be patient.

python apps/text_to_3d.py

⚡ API

Text-to-image based on the Kolors model.

bash embodied_gen/scripts/textto3d.sh \
    --prompts "small bronze figurine of a lion" "A globe with wooden base and latitude and longitude lines" "橙色电动手钻，有磨损细节" \
    --output_root outputs/textto3d

---

🎨 Texture Generation

Generate visually rich textures for 3D mesh.

☁️ Service

Run the texture generation service locally. Models downloaded automatically on first run, see download_kolors_weights, geo_cond_mv.

python apps/texture_edit.py

⚡ API

bash embodied_gen/scripts/texture_gen.sh \
    --mesh_path "apps/assets/example_texture/meshes/robot_text.obj" \
    --prompt "举着牌子的写实风格机器人，大眼睛，牌子上写着“Hello”的文字" \
    --output_root "outputs/texture_gen/" \
    --uuid "robot_text"
