I want to make this effect with HTML5, CSS, JS…

Do you mean in UE4, then building to HTML5?

Or do you mean in straight HTML, Js and CSS?

Not sure from your question. It’s also not clear if you want 3D geometry, or just a texture?

Hello mikepurvis!
Yeah, that’s true, I wasn’t clear, sorry :p.
Well, I want to create it in straight HTML, JS, CSS… I want a 3d geometry with random position (to which cubes will be ‘outside’, ‘inside’ or ‘normal’, like in the image)…

I would use the library three.js, this probably isn’t the best forum for web development questions.

You could build that in UE4 and compile it to HTML5.
