Augmented Reality (AR)
Augmented Reality (AR) is a technology that,through AR development,enhances the real-world environment by overlaying computer-generated information, such as images,or 3D models, onto the user's view of the physical world. Unlike virtual reality(VR), which creates a completely immersive digital environment,This AR app development process allows us to supplements the real world with additional information, making it an interactive and blended experience.
Virtual Reality (VR)
Virtual Reality (VR) is an advanced computer-driven simulation accessible through a headset, providing a comprehensive 360-degree view of a digitally created environment. Initially prominent in gaming, VR has expanded into education, healthcare, and business applications. Organizations utilize VR for employee training, allowing immersive engagement with real-life scenarios to enhance learning and skill development. The evolution of VR from entertainment to a versatile professional tool signifies its transformative impact across diverse industries.
ARCore and ARKit
ARKit and ARCore are augmented reality (AR) development platforms provided by Apple and Google, respectively. These platforms enable developers to create immersive and interactive AR experiences for iOS and Android devices.
Here are some key features and capabilities commonly found in AR development:
1. Motion Tracking:
Description: Accurate tracking of the device's position and orientation in real-time.
Use Cases: Placing virtual objects in the physical environment and ensuring they stay anchored as the device moves.
2. Environmental Understanding:
Description: Recognizing and understanding the real-world environment, including surfaces, objects, and their spatial relationships.
Use Cases: Placing virtual objects on flat surfaces, interacting with physical objects, and creating a seamless integration between the digital and physical worlds.
3. Surface Detection:
Description: Identifying flat surfaces, such as tables or floors, for placing virtual content.
Use Cases: Placing virtual furniture in a room, allowing users to interact with the environment by placing objects on surfaces.
4. Light Estimation:
Description: Adapting virtual objects to match real-world lighting conditions.
Use Cases: Ensuring that virtual objects cast realistic shadows and reflections, enhancing the overall visual coherence.
5. Augmented Reality Anchors:
Description: Anchoring virtual content to specific locations in the physical world.
Use Cases: Persistently placing virtual information, annotations, or objects at specific real-world locations for users to discover.
6. Face Tracking:
Description: Tracking facial features and movements for AR experiences involving faces.
Use Cases: Creating AR effects that respond to facial expressions, overlays, and masks.
7. Gesture Recognition:
Description: Detecting and interpreting user gestures for interaction with virtual content.
Use Cases: Allowing users to manipulate virtual objects, navigate AR interfaces, or trigger actions using gestures.
8. Image Recognition:
Description: Identifying and tracking specific images or objects in the real world.
Use Cases: Triggering AR content based on recognized images, such as posters, logos, or products.
React-native AR libraries
ViroReact: Open-Source AR VR development in React Native
Viro-react is a powerful open-source framework that unlocks the world of AR and VR app development within the familiar embrace of React Native. If you're already comfortable building apps with React Native, you're halfway there with Viro!
Documentation : [https://viro-community.readme.io/docs/overview]
Installation instructions
If you are starting a new project, please consider using Starter Kit as a basis for your app.
Step 1 : git clone https://github.com/ViroCommunity/starter-kit.git
Step 2 : cd starter-kit
Step 3 : npm install
Step 4 : npx pod-install (iOS)
Step 5 : npx react-native run-android or npx react-native run-ios
How to install viro react?
The instructions for manually installing the library and connecting it to an already-existing React Native project are provided below. As of right now, auto-linking is not supported.
$ npm install –save @viro-community/react-viro
Need some guidance? Check out our starter kit repo for detailed instructions on linking Viro React in different file locations.
Note : [For testing AR features on iOS, you'll need a physical device with an ARKit-compatible camera.]
What is a Scene?
Applications in ViroReact consist of Scenes, represented either by ViroScene or ViroARScene components. Scenes are the 3D equivalent of the Views found in most 2D application frameworks. They contain all the content that ViroReact renders in AR/VR: UI controls, 3D objects, lights, and more.
An application in ViroReact typically contains one or more of these Scene components contained in a ViroSceneNavigator or ViroARSceneNavigator.
Basic Scene
A simple <ViroScene> is provided below. The scene contains a single <ViroText> object, which displays the text 'Hello World'.
<ViroScene>
<ViroText text='Hello World' position={[0, -.1, -1]} />
</ViroScene>
ViroText
A component that provides 2D Text functionality.
ViroARSceneNavigator
ViroARSceneNavigator is the entry point for AR applications with Viro.
ViroARScene
The ViroARScene component allows developers to logically group their experiences and components and switch between them using the ViroARSceneNavigator.
Time to dive into the codey ocean, ready?
<ViroARScene>
<ViroAmbientLight color={‘#ffffff'} />
<Viro3DObject
source={objects_3D.bird_animated.obj}
type={objects_3D.bird_animated.type}
position={objects_3D.bird_animated.position}
scale={objects_3D.bird_animated.scale}
rotation={[0, 0, 0]}
animation={{…objects_3D.bird_animated.animation, run: true}}
dragType='FixedToWorld'
onDrag={() => {}}
/>
</ViroARScene>
export default () => {
return (
<ViroARSceneNavigator
autofocus={true}
initialScene={{
scene: HelloWorldSceneAR,
}}
style={styles.f1}
/>
);
};
3D Objects
The <Viro3DObject> component enables loading 3D objects (also known as models or meshes) into a scene.
The <Viro3DObject> defines the structure of the 3D object: its vertices, faces, and texture coordinates. The scene graph, or <ViroNode> node hierarchy, determines the orientation and placement of the object. And finally, the appearance of the object is defined by its materials.
Loading 3D Objects
Viro supports loading 3D models in FBX, GLTF and OBJ formats. Viro will load the geometry, textures, and lighting parameters in the file. For FBX Viro will additionally load all installed skeletal animations. OBJ files are loaded directly by setting the source attribute of <Viro3DObject>, while FBX files need to converted into Viro's own VRX format.
ViroAmbientLight
A light object that emits ambient light that affects all objects equally.
