Range of Points #5

Hi Brandon,

Why does it specifically work only for points in the range of [-1, 1]. Is there a way to make it work for all ranges of Points?

Sorry for the noob question.

Reading the code and the documentation it's seems that we define in the first line of the main the following octree size :

// Create a new Octree centered at the origin // with physical dimension 2x2x2 octree = new Octree(Vec3(0,0,0), Vec3(1,1,1));

so basically your space os bounded by -1 and 1. Now, I haven't use the code yet, but what you can do, if changing the code doesn't work for bigger numbers, is simply "scale" your numbers so fit into [-1,1] simply doing NUM/NUM_MAX where NUM is you number and NUM_MAX is the maximum value that your NUM can be.

cheers!
