Select or upload a image, then just click 'Generate'.
By mimicking the artist/craftsman modeling workflow, we propose CraftsMan (aka 匠心) 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.
If you found Crafts is helpful, please help to ⭐ the Github Repo. Thanks!
*please note that the model is fliped due to the gradio viewer, please download the obj file and you will get the correct mesh.
*If you have your own multi-view images, you can directly upload it.
