I used msvs and cuda12.0

Hi, I just got -1 as nest.first here const auto nest = lbvh::query_device(bvh_dev, lbvh::nearest(point), distance_calculator());
Could you help to explain what is the reason ?

Can you let me know if the problem with "return -1" have been solved or not?

It is observed at searching the closest line segments for set of points (after slight modifcation of your code - 2D case and all necessary functions are implemented for aabb construction for line segments and distance from point to line segment calculation).

Maybe you can describe the source of the problem?
