vanruesc / linear-octree Goto Github PK

My mistake, you can ignore this ;). I didn't use a fresh vector for each entry.

What are the usage cases?

Hi.

I've been trying to launch the demo page locally but with no luck. Github pages deployment is no more as well. Perhaps, it would be quicker to ask you directly here.
Is this implementation considered to be finished by you as an author? Besides raytracing logic.

Now chit-chat:

I been really drawn to this library as a solution to many of my use cases in a project I am working on. I've been coming back to it after trying many other methods and libraries like undirected graph and traditional sparse octrees. I am going to try and attempt to adapt this to a spherical coordinate system, as that would really hone in what I need that is no where to be found in npm-land. Thanks for the great library!

Hey, thanks for writing this cool library!

I'm interested in using it for a project to bake object occlusion data - link if you're interested :)

The api looks very well designed, only one problem I'm encountering is how to initialize the octree to exactly fit a Box3 (that I've previously made to fit my scene). Maybe I'm overlooking something but all the initialization methods described in the Readme don't work for me, in the sense that the tree bounds don't stay constant when I change the levels in the Keydesign (maybe that's a bug?).

What I'm looking for is an initialization method that takes a Box3 for bounds and divides that volume up in the way described by the Keydesign.

The following will only fit the scene bounds, if I set level = 1, but as soon as I increase the levels, it will no longer fit the bounds in size or position.

const sceneBounds = new Box3().copy(sceneGeometry.boundingBox);
const level = 3; 
const keyDesign = new KeyDesign(level, level, level);
const octree = new Octree(sceneBounds, keyDesign);

Best Regards

Edit: I'm on the train right now, but I can add screenshots later on if that would help - Cheers!
