Navigation is an essential part of any mobile app that has multiple screens leading to a variety of interactions for the user. Building a working navigation system often requires us to create a structure that allows for different kinds of navigators working together.

Using react-navigation, you can definitely nest different types of navigators in a React Native app. The term nesting, when it comes to navigators, refers to rendering one navigator inside a screen of another navigator.

The introduction of iOS 13 brought a major upgrade to Apple’s augmented reality framework. ARKit 3 arrived with a lot of interesting new features — people occlusion, motion tracking, simultaneous front and back camera, and collaborative support. These enhancements to ARKit strongly indicate Apple’s ambition for pushing AR immersion even further.

Up until iOS 12, we had SceneKit, SpriteKit, and Metal as the primary rendering frameworks. Among these, SceneKit, the 3D graphics framework, had been the most logical choice for building ARKit apps.

OpenCV is a powerful tool for doing intensive computer vision operations in real-time, even on resource-limited mobile devices. Throughout a couple of tutorials, we’re going to create an Android app that applies various image effects. Some of these effects might use just 1 image, while others might use more than 1 image.

Tesla’s Autopilot is certainly the most advanced in the world. If Comma.ai is the Androïd, Tesla is definitely the Apple of self-driving cars. Recently, Tesla has released “Tesla Vision”, their new system equipped only with cameras… making it one of the only companies in the world not to use RADARs!

This is not the only place where Tesla is going against the crowd, their entire strategy is based on fleet and selling products, while most of its competitors sell autonomous delivery and transportation services. You can learn more about it on my article on Tesla vs Waymo here.
