React-Markerless-Ar-Rendering-Component

# React-Markerless-Ar

React-Markerless-Ar is a React-based library for rendering 3D models in a markerless augmented reality environment. It provides two main components: ModelViewer and AnimationViewer, which allow you to display static and animated 3D models, respectively.

This library was created by CowTheGreat and is now open source, allowing the community to contribute and improve it.

## Installation

Install the package via npm:

```bash

npm install @cow-the-great/react-markerless-ar

```

## Components

### 1. ModelViewer

The ModelViewer component is used to render static 3D models.

#### Props

| Prop Name | Type | Default Value | Description |

| ----------------- | ------------------ | -------------- | ---------------------------------------------------------------- |

| modelPath | string | Required | Path to the 3D model file (e.g., .glb or .gltf). |

| width | string \| number | "100%" | Width of the viewer container. |

| height | string \| number | "400px" | Height of the viewer container. |

| cameraProps | object | {} | Camera configuration (position, fov, near, far). |

| lightingProps | object | {} | Lighting configuration (ambient and directional light settings). |

| modelProps | object | {} | Model configuration (scale and position). |

| controlsProps | object | {} | OrbitControls configuration (zoom, pan, rotate, etc.). |

| backgroundProps | object | {} | Background configuration (camera feed, plane size, etc.). |

| id | string | Auto-generated | Unique identifier for the viewer instance. |

### 2. AnimationViewer

The AnimationViewer component is used to render animated 3D models.

#### Props

| Prop Name | Type | Default Value | Description |

| ----------------- | ------------------ | ------------- | ---------------------------------------------------------------- |

| modelPath | string | Required | Path to the animated 3D model file (e.g., .glb or .gltf). |

| width | string \| number | "100%" | Width of the viewer container. |

| height | string \| number | "400px" | Height of the viewer container. |

| cameraProps | object | {} | Camera configuration (position, fov, near, far). |

| lightingProps | object | {} | Lighting configuration (ambient and directional light settings). |

| modelProps | object | {} | Model configuration (scale and position). |

| controlsProps | object | {} | OrbitControls configuration (zoom, pan, rotate, etc.). |

| backgroundProps | object | {} | Background configuration (camera feed, plane size, etc.). |

## Usage

Here is an example of how to use the components:

```tsx

import React from "react";

import {

ModelViewer,

AnimationViewer,

} from "@cow-the-great/react-markerless-ar";

function App() {

return (

<>

<AnimationViewer

modelPath="animated_model.glb"

width="100vw"

height="100vh"

cameraProps={{

position: [0, 2, 5],

fov: 60,

}}

lightingProps={{

ambientLightIntensity: 0.8,

directionalLightPosition: [5, 5, 5],

}}

modelProps={{

scale: 2,

position: [0, 0, 0],

}}

backgroundProps={{

enableCamera: true,

planeSize: 30,

}}

/>

<ModelViewer

modelPath="static_model.glb"

width="700px"

height="600px"

cameraProps={{

position: [0, 2, 7],

fov: 45,

}}

lightingProps={{

ambientLightIntensity: 0.8,

directionalLightPosition: [5, 5, 5],

}}

modelProps={{

scale: 2.0,

position: [0, -1.5, 0],

}}

controlsProps={{

enableZoom: true,

zoomSpeed: 1.0,

}}

backgroundProps={{

enableCamera: true,

planeSize: 25,

}}

/>

</>

);

}

export default App;

```
