Hi, I’m trying to demonstrate BoundingVolume SUBDIVISION, and I was thinking if it’s able to subdivide a Box3Helper . Or how to convert the Box3Helper to an object? My Example: createBoundingVolumes() { for(var i=0; i<groupOfObjects.length; i++) { var BV = new THREE.BoxHelper( grou…

Can you explain what do you mean by subdivision?

This basically [image] And then I want to remove the cubes that does NOT contain a mesh.

UPDATE Is there a way to return the bufferGeometry of BoxHelper? I tried using this function BV_Create(){ for(var i=0; i<groupOfObjects.length; i++) { var BV = new THREE.BoxHelper( groupOfObjects[i], 0xffff00 ); BV.update(); bv_List[i] …

[image] Loizos_Vasileiou: var thisBufferGeometry = new THREE.BoxBufferGeometry().fromGeometry(bv_List[i]); //Also tried bv_List[i].geometry The BoxBufferGeometry can’t be constructed the way you’ve tried. Please try: //Declare a Vector3 var tempV = new THREE.Vector3(); ... // In the loop: bv…

UPDATE: BV_Create() { for(var i=0; i<groupOfObjects.length; i++) { var BV = new THREE.BoxHelper( groupOfObjects[i], 0xffff00 ); BV.update(); bv_List[i] = BV; bv_List[i].material.visible = false; //Set true in draw() function scene_Main.add(BV); //Add object to the sc…

I found out that by using either of this it will create want I want but in the wrong position. bv_List[i].geometry.boundingBox.getCenter( bv_List[i].object.position ); bv_List[i].geometry.boundingBox.getCenter( groupOfObjects[i].position ); [image]

PLEASE do not delete your old posts, they are useful for reference. Without them what I say has no meaning. Please try: BV_Create() { for(var i=0; i<groupOfObjects.length; i++) { var BV = new THREE.BoxHelper( groupOfObjects[i], 0xffff00 ); BV.update(); bv_List[i] = BV; bv…

[image] Loizos_Vasileiou: //Line 638 - Error message bv_List[i].geometry.boundingBox.getCenter( thisBufferGeometry.position ); Oh, this was supposed to be .getCenter( grid.position );

Is it possible to subdivide a Box3Helper?
