shap-e - Text and Image-Based Conditional 3D Model Generation

Shap-E: An Introduction to Generating Conditional 3D Implicit Functions

Shap-E is an innovative project aimed at transforming how we perceive and generate 3D models. Officially released with its code and model, Shap-E promises to bring creative, conditional 3D modeling to a broader audience. Let's delve into what this project offers, using approachable and straightforward language.

What is Shap-E?

Shap-E stands for generating conditional 3D implicit functions. Simply put, it allows users to create complex and imaginative 3D models based on input prompts, which can be either text or images. Imagine describing something bizarre like "a chair that looks like an avocado" and then seeing that concept come to life in a 3D model. That's the magic Shap-E offers.

Key Features and Usage

Shap-E's primary allure is its text-conditional model, which can turn a text prompt into a 3D object. Users keen to explore and utilize Shap-E can begin by installing it via a simple command using pip install -e .. The project provides valuable resources for getting started, including example notebooks:

Text to 3D Model: The sample_text_to_3d.ipynb notebook guides users in generating 3D models from a text prompt. This notebook is the gateway to seeing your ideas come into a digital existence.
Image to 3D Model: Do you have an image with a unique view? The sample_image_to_3d.ipynb notebook can sample a 3D model based on a synthetic view image. For the best results, ensure the background of your image is removed.
Model Encoding: In encode_model.ipynb, users can load a 3D model or mesh, create a series of multiview renders and point clouds, encode these into a latent space, and render them anew. For this feature, Blender version 3.3.1 or higher is necessary, and you'll need to set the BLENDER_PATH environment variable correctly to use Blender.

Exploring Shap-E's Samples

The creative potentials of Shap-E are best illustrated through its samples. The project showcases various unique 3D models generated through text prompts, including:

A chair that appears like an avocado.
An airplane styled like a banana.
Spaceship designs.
Whimsical items like a birthday cupcake and a penguin.

These samples not only demonstrate the wide-ranging capabilities of Shap-E but also spark inspiration for users to create their unique models. For those interested in more examples or wishing to test the model with prompts, further exploration can be done through the samples.md file available in the repository.

Contributing and Future Prospects

As with many open-source projects, Shap-E is a collaborative effort. Enthusiasts and developers can contribute to its growth, improve functionality, or diversify its applications. The project, rooted in both technological advancement and creative exploration, stands to evolve as more users and developers engage with it.

In conclusion, Shap-E represents a significant step in 3D modeling technology, inviting users to reimagine and materially recreate their conceptual visions. Whether you're a hobbyist with a penchant for digital art or a developer eager to push the boundaries of 3D modeling, Shap-E offers a platform ripe with possibilities.
