Chapter 1: Introduction to A-Frame
1.1 The Genesis of A-Frame
A-FRAME, AN OPEN-SOURCE web framework for building virtual reality (VR) experiences, emerged in response to the growing interest in web-based VR content creation. Prior to A-Frame’s development, creating VR content for the web was a complex and fragmented process. Developers had to rely on proprietary solutions, specialized tools, and intricate code to bring VR experiences to the web.
The Need for a Simplified VR Development Approach
AS THE DEMAND FOR VR content increased, there was a clear need for a more accessible and standardized way to create VR applications for the web. A-Frame was conceived as a response to this challenge. It aimed to democratize
