How to keep track of the order of d_points after calling buildTree?

[jizhu1023]

Thanks for your great work! It's been incredibly useful for my projects.

I'm currently integrating it into a new application and need to keep track of the original order of d_points after calling buildTree. Could you advise on how to achieve this or if there's a way to map the original indices to their new positions after buildTree runs?

Appreciate any help you can provide!

Using Non-Default Data Types should help.

struct PointPlusIndex{
  float3 position;
  int    index;
};
