Questions on keyframe selection

[GTP]

Hello, I have a question on keyframe selection method in your paper.
It your paper, keyframe is determined by ray intersection test.
In this case, should ray be a dense 2D rays or sampled rays?
I think that there's no need to test all rays inside camera view, but it may require more rays than the tracking process.

Thanks for sharing the cool work.

Hi, it is actually a "voxel" intersection test, not "ray". It computes the overlap between incoming voxels and existing voxels.

However, we haven't included this feature in this clean version yet. We will update it later.
