I would like to render a <div> (in my case it's one of the ECharts) with Three.js CSS3DRenderer and combine it with WebGL content, but with fixed width and height, the rendering quality is not good when zooming in as it was rendered with fixed width and height. Therefore, I wonder is there a way to increase the rendering resolution when rendering the <div> with CSS3DRenderer (NOT the devicePixelRatio of <div>)? Thanks in advance!
