Enhance your .obj files by incorporating buttons using three.js

I am currently using three.js to load multiple obj files into a scene. These files combine to create a single unit. My objective is to enable users to customize the color of each part of this rendered unit. I am attempting to place buttons on each section of the unit so that users can click on them to access different customization options for that specific part. However, I am facing challenges in adding child objects to the various components of the unit. Any assistance or guidance on how to approach this would be highly valued.

Answer №1

When the mouse hovers over an object, I am able to display a tag on that object using a raycaster.

//Defining a vector to project the mouse onto objects
var vector = new THREE.Vector3(mouseX, mouseY, 1);
projector.unprojectVector(vector, camera);

raycaster.set(camera.position, vector.sub(camera.position).normalize());
// Finding the intersected object
var intersects = raycaster.intersectObjects(scene.children);

if (intersects.length > 0) {
   var intersected = intersects[0].object;
   // The drawtag method is defined on the object to draw additional elements like shapes and text
   intersected.drawTag();
}
