Virtual Reality – The path to create your world

What if you could build a VR world with just a few lines of HTML? Learn how the A-Frame framework makes immersive experiences accessible to any web developer.

#1about 4 minutes

Defining the core concepts of virtual reality

Virtual reality is an artificial software-created environment that immerses the user, making them accept the virtual world as real through sight and sound.

#2about 2 minutes

Understanding the difference between VR and AR

Virtual reality immerses the user into a digital environment, whereas augmented reality brings digital objects into the user's real-world environment.

#3about 4 minutes

Exploring the real-world applications of VR

VR has practical applications beyond entertainment, including flight simulators for training, immersive fitness experiences, and high-risk educational simulations for surgery.

#4about 7 minutes

Building cross-platform VR experiences with A-Frame

A-Frame is a web framework that lets you build VR experiences using simple HTML, making it accessible and compatible with most headsets, desktops, and mobile devices.

#5about 4 minutes

How the Entity Component System organizes VR scenes

The Entity Component System (ECS) architecture provides a manageable pattern for building complex 3D objects by separating entities, components, and systems.

#6about 3 minutes

Coding a basic VR scene with A-Frame primitives

Learn to create a simple VR scene by adding primitive shapes like boxes and spheres using HTML-like tags and attributes for position, rotation, and color.

#7about 4 minutes

Making your VR world interactive with A-Frame

Enable user interaction through methods like gaze-based controls for controller-less headsets and by manipulating scene elements using standard JavaScript and DOM APIs.

#8about 4 minutes

Showcasing VR experiences built with A-Frame

Explore examples of what's possible with A-Frame, including an interactive musical forest and a space shooter, and get encouraged to build your own VR world.
