# Visual Core for 3D AI Agents

Learn how the Virtuals Protocol Visual Core powers interactive 3D AI agents with rigged characters, facial animation, MMD models, and Three.js rendering.

Visual Core turns VIRTUAL agents into interactive 3D AI characters. It combines visual identity, animation, and facial expressions for more engaging experiences than text-only chatbots.

Each VIRTUAL agent can use a rigged 3D character with animation and facial expressions. Create characters with 3D editors that support MMD files. dApps can render these 3D AI avatars with frontend frameworks such as the Three.js MMD loader.

The planned Virtuals SDK will streamline 3D character display in applications.

### Challenges of creating 3D AI characters

1. **Rigged 3D character production:** Creating and maintaining fully rigged, animated 3D characters requires significant time and specialist skills.
2. **3D animation and hosting:** Rendering lifelike AI avatars requires animation expertise, 3D models, scene positioning, and reliable hosting. Teams often combine technical and artistic specialists to create realistic interactions.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://whitepaper.virtuals.io/about-virtuals-1/the-protocol/ai-agent-co-contribution-and-provenance/modular-consensus-framework-for-ai-agent-governance/decentralized-ai-agent-contributions-and-nfts/visual-core-for-3d-ai-agents.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
