Exploring the shine: implementing reflection in THREE.js

Is there a way to achieve a material that reflects other shapes from the scene? I attempted to use the reflectivity property but had no success in seeing any reflection.

I found an example demonstrating this effect

It seems like non-standard materials were utilized in achieving this effect.

Answer №1

Exploring the concept further: a reflection essentially captures an image of the surroundings from a specific point of view. If you wish to use a planar mesh as a mirror, it requires positioning a camera at that exact spot, rendering the scene into a texture during the animation loop, and then integrating that texture into the material for the planar mesh. Additionally, I suggest delving into along with the examples highlighted by WestLangley.

Experimenting with different configurations can yield varying results; to achieve a less reflective outcome, consider attempting:

var mirrorMaterial = new THREE.MeshBasicMaterial( { color: 0x111111, envMap: mirrorCamera.renderTarget } );

or

var mirrorMaterial = new THREE.MeshPhongMaterial( { emissive: 0x111111, envMap: mirrorCamera.renderTarget } );

Here is an example of using THREE.MeshLambertMaterial with a texture and environment map:
new THREE.MeshLambertMaterial ({
    map: texture,    
    envMap: scene.background,      
    combine: THREE.MixOperation,     
    reflectivity: .5     
})

The important variable to note here is THREE.MixOperation
