Farm3D is a software that can generate controllable 3D models from a single image. It uses the image generation model Stable Diffusion to produce training data, enabling it to learn a monocular reconstruction network. This network can generate detailed 3D models from a single input image, including shape, appearance, viewpoint, and lighting direction. Farm3D is suitable for designers, artists, and model makers, enabling them to quickly generate high-quality 3D models.
