Has anyone ever implemented "Projective Displacement Mapping for Ray Traced Editable Surfaces"?
If so, can I get some help? I cant solve these offsets between triangle boundaries for the life of me and I am totally stuck again(this is exactly what stopped me last time),any tips?

TinyBVH 1.6.6 is out on main. Changes:
* Improved speed of FullSweep (thanks Julian)
* Reverted JobSystem to basic threading because of instabilities
* Wave_tracer now uses TinyBVH!
* Fixed speedtest of GPU BVH
Because of the threading issue: Please upgrade to 1.6.6 asap.

Working on a small primer on frustum grids.
The most common approach is to distribute the depth-slices in an "exponential" manner between a near and far plane, which is probably more appropriately named "geometric" since it relies on a geometric progression.

Frustum Grids Primer Part 2:
This time instead of having a fixed depth-slice count (which is common for games for a variety of reasons) we'll instead focus on trying to maintain a uniform and non-elongated froxel shapes, which results a variable slice count
