Ways to conceal and reveal an item within a three.js environment

In my scene, I have an object made up of spheres and a hide/show button. The process in my program goes like this: when I choose one of the spheres using raycasting and then press the hide button, that particular sphere becomes hidden. Clicking on the show button will reveal the previously hidden sphere. However, I am unsure about how to achieve this functionality. I am using three.js for developing my scene and so far, I haven't come across any examples or resources addressing my specific query. Can someone guide me on how to accomplish this? Your assistance is greatly appreciated.

Answer №1

Utilize the object traverse method in three.js to easily conceal a mesh. In my particular code, I hide the object based on its assigned name

object.traverse ( function (child) {
    if (child instanceof THREE.Mesh) {
        child.visible = true;
    }
});

For a working example of how to show/hide objects, check out this sample: http://jsfiddle.net/ddbTy/287/

I believe this demonstration will be quite useful...

Answer №2

Give this a shot:

object.isVisible = false; //Hidden
object.isVisible = true;  //Displayed
