What are the methods for incorporating reflection into three.js?

While working on a WebGL project using Three.js, I am aiming to incorporate a reflective cube surface that mimics the appearance of a mobile phone display. The surface should be able to reflect light while maintaining a black color scheme.

Answer №1

Showing off my latest creation - a reflective cube and sphere complete with detailed explanations. You can check out the live version right here:

And don't forget to peek at the beautifully formatted code on this link:

https://github.com/stemkoski/stemkoski.github.com/blob/master/Three.js/Reflection.html

(These examples are part of an ongoing tutorial collection found at )

Key takeaways include:

  • Integrate a secondary camera (CubeCamera) into your scene positioned towards the object needing reflection.
  • Create a material and apply the environment map as the outcome from rendering with this additional camera, like so:

For instance:

 var mirrorCubeMaterial = new THREE.MeshBasicMaterial( 
    { envMap: mirrorCubeCamera.renderTarget } );
  • In your rendering function, ensure to render using all cameras. Temporarily conceal the reflecting object during the camera's use, then reveal it after rendering.

For example:

mirrorCube.visible = false;
mirrorCubeCamera.updateCubeMap( renderer, scene );
mirrorCube.visible = true;

These snippets come directly from the links I shared above; dive in for more details!
