Within a dynamic scene, multiple mesh objects (specifically cubes) have been included. A unique EdgeHelper has been generated for each cube to track its movements and rotations.
Whenever a particular cube mesh is selected, I am aiming to alter the color of its corresponding EdgeHelper object. The method used for selection is not crucial in this case.
Thus, my main query revolves around identifying the specific EdgeHelper object linked to a given cube mesh.
When adding an edgesHelper to a specific mesh, you simply need to create the helper object and assign it as a new property of the mesh:
var mesh = new THREE.Mesh( ... );
var edgesHelper = new THREE.EdgesHelper( mesh );
mesh.edgesHelper = edgesHelper;
To update the color of the helper, use the following code:
mesh.edgesHelper.material.color.set( 0xff0000 );
This functionality is available in three.js version r.76
Assigning the same .name attribute to meshes and EdgeHelpers is a common practice:
mesh0.name = 0;
edgeHelper0.name = 0;
mesh1.name = 1;
edgeHelper1.name = 1;
...and so forth
**if you put this in a loop, it's even more efficient
This allows for easy retrieval of the corresponding edgeHelper when a mesh is selected based on its .name attribute.
