Creating a customizable and refining a model in the browser with ThreeJS or X3DOM

I am currently exploring the use of ThreeJs to display STL files directly in a web browser. However, I am interested in finding a way to add customizable parameters to these models, allowing for easy editing using either ThreeJs or X3DOM. For instance, I would like to be able to add a text parameter to a cube model, which would then be embossed onto the cube at a specific location.

I am willing to convert the STL files to either ThreeJS model Js files or X3D files, as long as I can find a way to parameterize the rendering process in order to add text or other elements to the basic structure.

I am curious if anyone has experience working with this type of 3D parameterization and customization.

Is it possible to achieve this within ThreeJS or X3DOM?
If so, is there any relevant documentation or resources available to guide me through this process?

If these libraries are not capable of handling this type of parameterization, are there other libraries or tools that could accomplish the same goal?

Edit My primary question revolves around the ability to add parameters directly to the model itself. Is there a way for ThreeJS models to inherently understand and utilize parameters without requiring extensive customization? For example, if I were to adjust the side length parameter of a cube model from 1 to 3, could ThreeJS automatically render a larger cube based on this change?

One approach to consider, although it may not directly address your query, is to develop a subclass of a blank 3D object and implement your desired effects programmatically once the foundational model is loaded.

For illustration purposes, here's an example using three.js (ideally in a separate file):

var EmbossedCube = function( text, onLoaded ) {
  THREE.Object3D.apply(this);

  var self = this;
  var loader = new THREE.STLLoader();

  loader.addEventListener( 'load', function ( event ) {
    var material = new THREE.MeshPhongMaterial( { ambient: 0xff5533 } );

    // Customize the material or geometry based on the 'text' input

    var mesh = new THREE.Mesh( event.content, material );

    // Make local transformations to the mesh as required

    self.add( mesh );
    onLoaded && onLoaded( self );
  } );

  loader.load( './model.stl' );
};
EmbossedCube.prototype = Object.create( THREE.Object3D.prototype );

// Additional methods for EmbossedCube

EmbossedCube.prototype.constructor = THREE.Object3D;

Following this, you can instantiate an object of this type and incorporate it into your scene:

var cube = new EmbossedCube("beep", function(obj){
  // Perform translations or rotations on the object if necessary
  scene.add( obj );
});

While this may not be the most straightforward approach, it does offer potential for enhanced reusability in the future.

Discover the capabilities of the va3c viewer, offering the option to open files from REVIT, grasshopper, and more.

Consider opening your files in Rhino + GH first, setting the necessary parameters, and then importing them into va3c.

This idea is just a suggestion and I will need an actual file with specific details to test it out.

Let me know if this method proves successful!
