How do I display <iframe>s as a texture in A-Frame?

Question

I want to display webpages as 2D content with a VR scene. Can I use an <iframe> element as a source for a texture in WebGL/three.js in https://aframe.io?

Answer 1

You can't use iframes or any other HTML element inside WebGL as it would be a security risk. People could read passwords and other private info from the textures.

you can however find creative solutions like this one which is the first hit of googling "iframe webgl".

You do it by putting a iframe behind a webgl canvas, using 3d math cut a hole (draw transparent pixels) where you need the iframe to show through by using a 2d plane that represents the iframe. Then use 3D css to position the iframe element to match the plane.
