Description

Recent advancements in the realm of text-to-image synthesis have emerged from diffusion models that have been trained on vast amounts of image-text pairs. To successfully transition this methodology to 3D synthesis, it would necessitate extensive datasets of labeled 3D assets alongside effective architectures for denoising 3D information, both of which are currently lacking. In this study, we address these challenges by leveraging a pre-existing 2D text-to-image diffusion model to achieve text-to-3D synthesis. We propose a novel loss function grounded in probability density distillation that allows a 2D diffusion model to serve as a guiding principle for the optimization of a parametric image generator. By implementing this loss in a DeepDream-inspired approach, we refine a randomly initialized 3D model, specifically a Neural Radiance Field (NeRF), through gradient descent to ensure its 2D renderings from various angles exhibit a minimized loss. Consequently, the 3D representation generated from the specified text can be observed from multiple perspectives, illuminated with various lighting conditions, or seamlessly integrated into diverse 3D settings. This innovative method opens new avenues for the application of 3D modeling in creative and commercial fields.

Description

This is the formal release of the Shap-E code and model, which allows users to create 3D objects based on textual descriptions or images. You can generate a 3D model by providing a text prompt or a synthetic view image, and for optimal results, it's recommended to eliminate the background from the input image. Additionally, you can load 3D models or trimeshes, produce a series of multiview renders, and encode them into a point cloud, which can then be reverted to a visual format. To utilize these features effectively, ensure that you have Blender version 3.3.1 or a more recent version installed on your system. This opens up exciting possibilities for integrating 3D modeling with AI-driven creativity.
