_TITLE = '''CraftsMan: High-fidelity Mesh Generation with 3D Native Generation and Interactive Geometry Refiner'''
_DESCRIPTION = '''
<div>
Select or upload a image, then just click 'Generate'.
<br>
By mimicking the artist/craftsman modeling workflow, we propose CraftsMan (aka ε εΏ) that uses 3D Latent Set Diffusion Model that directly generate coarse meshes,
then a multi-view normal enhanced image generation model is used to refine the mesh.
We provide the coarse 3D diffusion part here.
<br>
If you found CraftsMan is helpful, please help to β the <a href='https://github.com/wyysf-98/CraftsMan/' target='_blank'>Github Repo</a>. Thanks!

<br>
*If you have your own multi-view images, you can directly upload it.
