Currently working on a web app that utilizes Three.js (Javascript) and the VR features for mobile devices, with a focus on Android. One issue I've encountered is that after a while, the screen dims and shuts off. I've searched for an API to prevent this, but haven't had any luck finding information. Interestingly, when you visit and run their demos, the screen remains active. I attempted to analyze their code but couldn't locate the solution. How are they achieving this? Thank you.
