Hello, I’m very new to Threejs but not programming. I’m starting a project, I’m trying to build a Cubequadtree (customer cube object that has a Quadtree for each side). The problem I’m running into currently is how do I form 6 bounding boxes so that they make a cube?
Hi!
How the result has to look like?
just a regular cube object that is made of bounding boxes for each side. the confusion that I have is how do I stitch these bounding boxes together so that they look like a cube. It should look like this https://www.osd.net/blog/wp-content/uploads/2013/04/webgl_3d_checkers_testing_cube.jpg
no looking to create fat line edges.
Are you talking about boxes (width x height x depth) or rectangles (width x height)?
Width 1px width edges, it’s even shorter:
var boxGeometry = new THREE.BoxBufferGeometry( 20, 20, 20 );
var edgesGeometry = new THREE.EdgesGeometry( boxGeometry );
var edgesMaterial = new THREE.LineBasicMaterial( { color: 0x4080ff } );
var wireframe = new THREE.LineSegments( edgesGeometry, edgesMaterial );
I stumbled upon this solution you gave, to build a box out of planes. Which is partially the answer to my problem. I just need to build a 6 sided box out of Box3
Box3 is a math object.
If you want to build a cube of 6 thin boxes, won’t they have cross sections in cube’s corners?
Maybe you’ll need to build something similar to this: Get OrbitControls Azimuth Angle - #2 by prisoner849
I’m trying to re-engineer a tutorial I saw on how to Generating Procedural Planets with Level-of-Detail: 3D World Generation: #4 (Planetary LOD): Generating Procedural Planets with Level-of-Detail! - YouTube
you can jump to the 1:02 mark he starts to dive into the code. I’m not sure why he opted to use a Box3 to define each side of the box but I want to find out the reason.
