Shap-e offers promising features for designers, artists, developers, and anyone looking to explore the possibilities of AI-assisted 3D modeling. So, let's embark on this fascinating journey.

About Shap-e

Created by cjwbw, Shap-e is a model that generates conditional 3D implicit functions. These functions form the basis for creating intricate 3D shapes based on input conditions. By employing neural networks, Shap-e understands the relationship between input conditions and the shape of the object. This makes it an invaluable tool for a broad range of applications including 3D modeling, computer graphics, virtual reality, and even scientific simulations. Find more about the creator and model on the creator page and the model details page respectively.

Whether it's generating realistic and customized 3D objects for video games, animations, and virtual reality environments, or creating complex architectural designs, Shap-e opens up a world of creative possibilities. It even allows for scientific simulations to generate accurate 3D representations of objects or environments.

Understanding the Inputs and Outputs of Shap-e

Before diving into how to use Shap-e, it's crucial to understand the inputs it takes and the outputs it produces. Knowing this can significantly enhance your user experience and help you get the most out of the model.

Inputs

Shap-e receives several inputs that dictate the 3D shape that will be generated. These include:

• prompt: This is a text prompt for generating the 3D model, but it's ignored if an image is provided.
• image: A synthetic view image used for generating the 3D model. For optimal results, it's recommended to remove the background from the input image.
• guidance_scale: This sets the scale for guidance, with the default value set at 15.
• batch_size: Specifies the number of outputs. The default value is 1.
• render_mode: Allows you to choose a render mode, either 'nerf' or 'stf'. The default value is 'nerf'.
• render_size: This sets the size of the renderer, and higher values take longer to render. The default value is 128.
• save_mesh: If set to true, this saves the latents as meshes.

Outputs

In response to the inputs, Shap-e provides an array of URIs corresponding to the generated 3D models. The raw JSON schema of the model's output structure is as follows:

{
  "type": "array",
  "items": {
    "type": "string",
    "format": "uri"
  },
  "title": "Output"
}

Step-by-step Guide to Using Shap-e

After understanding the inputs and outputs, it's time to explore how to use Shap-e. This section will provide a step-by-step guide to using this model for creating intricate 3D shapes.

If coding isn't your cup of tea, Shap-e also comes with a demo. Though currently, there's no demo available for Shap-e, you can check the demo link for future updates. It's a great way to experiment with the model's parameters and receive instant feedback. For those keen on coding, the steps below will guide you on how to interact with Shap-e's Replicate API.

Step 1: Install the Client

First, install the Node.js client with the following command:

npm install replicate

Step 2: Set API Token

Next, authenticate by setting your API token as an environment variable:

export REPLICATE_API_TOKEN=r8_*************************************

This is your Default API token, which should be kept private.

Step 3: Run the Model

Then, run the model:

import Replicate from "replicate";

const replicate = new Replicate({
  auth: process.env.REPLICATE_API_TOKEN,
});

const output = await replicate.run(
  "cjwbw/shap-e:5957069d5c509126a73c7cb68abcddbb985aeefa4d318e7c63ec1352ce6da68c",
  {
    input: {
      prompt: "..."
    }
  }
);

You can also set a webhook URL to be called when the prediction is complete. Check out the webhook docs for details on setting that up.
