CLIP-Forge: Towards Zero-Shot Text-to-Shape Generation

While recent progress has been made in text-to-image generation, text-to-shape generation remains a challenging problem due to the unavailability of paired text and shape data at a large scale. We present a simple yet effective method for zero-shot text-to-shape generation based on a two-stage training process, which only depends on an unlabelled shape dataset and a pre-trained image-text network such as CLIP. Our method not only demonstrates promising zero-shot generalization, but also avoids expensive inference time optimization and can generate multiple shapes for a given text.
