Fabrik Viewer

Fabrik Viewer is a powerful React component for rendering interactive 3D scenes with hotspots, custom models, and dynamic camera controls.

Features

• 3D Model Rendering: Supports GLTF/GLB files for rich, detailed 3D visualizations.
• Interactive Hotspots: Customizable appearance and behavior for interactive elements within the scene.
• Dynamic Camera Controls: Adjust the camera position, zoom, pan, and rotation for flexible scene navigation.
• Custom 3D Text Elements: Integrate 3D text directly into your scenes.
• Background Color Customization: Change the background color to fit your application's theme.
• Responsive Design: Automatically adjusts to various screen sizes for a consistent user experience.

Installation

To install the Fabrik Viewer package, run the following command:

npm install @fabrikspace/viewer

Usage

Here's a basic example of how to use the Fabrik Viewer component in a React application:

import React, { useEffect, useState } from 'react';
import { Viewer } from '@fabrikspace/viewer';

function App() {
  const [cpd, setCpd] = useState(null);

  useEffect(() => {
    // Load your CPD (Content Presentation Data) file
    fetch("cpd.json")
      .then((res) => res.json())
      .then((data) => {
        setCpd(data);
      });
  }, []);

  return (
    <div style={{ width: '100vw', height: '100vh' }}>
      {cpd && <Viewer cpd={cpd} />}
    </div>
  );
}

export default App;

CPD (Content Presentation Data) Structure

The Viewer component requires a CPD object with the following structure:

interface CPD {
  steps: { [key: string]: StepData };
  initial_step_id: string;
  modelUrl: string[];
}

interface StepData {
  step_info: {
    properties: {
      bgColor?: string;
    };
    control: {
      cameraPosX: number;
      cameraPosY: number;
      cameraPosZ: number;
      cameraLookX: number;
      cameraLookY: number;
      cameraLookZ: number;
      maxZoom: number;
      minZoom: number;
      enablePan: boolean;
      enableZoom: boolean;
      enableRotate: boolean;
      enableDamping: boolean;
    };
  };
  hotspot_disabled: boolean;
  step_model_url: ModelData[];
  hotspot: HotspotData[];
}

interface ModelData {
  name: string;
  custom_model_type?: string;
  threedtext?: string;
  mesh_properties?: MeshProperty[];
}

interface MeshProperty {
  name: string;
  properties: {
    position: Vector3;
    rotation: Vector3;
    scale: Vector3;
    mesh_color?: string;
    hidden?: boolean;
    mesh_transparency?: number;
  };
}

interface Vector3 {
  x: number;
  y: number;
  z: number;
}

interface HotspotData {
  xPos: number;
  yPos: number;
  zPos: number;
  title: string;
  bgColor?: string;
  textColor?: string;
  goToStep?: string;
  api_url?: string;
  polling_interval?: number;
  size?: number;
  api_content?: boolean;
}

Configuration

Step Configuration

Each step in the CPD object can be configured with the following properties:

• Camera: Position, look-at point, and control settings (zoom, pan, rotate).
• Background: Customizable background color.
• Hotspots: Define interactive elements with specific actions, positions, and styles.
• 3D Models: Load models with specific properties such as position, rotation, scale, color, and visibility.

Hotspots

Hotspots can trigger step changes or display custom content. They can be configured with:

• Position (x, y, z coordinates)
• Color (background and text)
• Size and behavior (e.g., API calls, polling)

3D Models

Models are loaded from URLs specified in the CPD and can have properties like:

• Position, rotation, scale
• Color and transparency
• Visibility settings
