What is the procedure for obtaining a hexadecimal hex color value and applying it to the LambertMaterial function in three.js

I'm currently facing a small issue with retrieving hex colors in my project. I have a simple variable that stores colors:

var colors = {
    "C":0x000000,
    "H":0xffffff,
    "O":0xff0000,
    ...
}

The goal is to retrieve the color by key using the function below (written in TypeScript):

getAtomColor(element: string) :number{
    for (var key in colors) {
        if (element == key) {
            return colors[key];
        }
    }
}

The issue arises when passing the atom color (represented as parameter clr) in integer form, resulting in undefined parameters in the `THREE.MeshLambertMaterial({color:clr})` function from three.js. How can I address this problem?

Answer №1

One way to ensure that you receive '0x000000' instead of 0 is by modifying your object to store the values as hexadecimal strings.

var colors = {
    'C': '0x000000',
    'H': '0xffffff',
    'O': '0xff0000',
}

Alternatively, you can choose to save them as THREE.color objects...

var colors = {
    'C': new THREE.Color(0x000000),
    'H': new THREE.Color(0xffffff),
    'O': new THREE.Color(0xff0000),
}
