hilbert curve top/bottom pattern

[gz2k2]

hi,

I know that hilbert curves as top/bottom pattern result in an insane amount of printer movements, but the result just looks great. please implement it like slic3r does :)

I can't imagine I would use it myself but as it's been a rainy day I've got something working...

It's still got some problems so I won't be releasing it just yet but it will appear in the future.

I don't use slic3r myself so perhaps you can answer a question for me. If you slice an object whose cross section varies with height (like a sphere or pyramid), does the hilbert infill remain the same pattern through all of the layers or does it alter in any way (i.e scale, shift or rotate)?

On my point of view Hilbert infill in Slic3r or Prusa Slicer is just crap. It's not a real Hilbert trajectory (Ie : fill one layer starting from one point and finishing to an other point without retraction) but just a pattern with a lot a direction change and retraction so utility of this solution ????

Same for the Top/Bottom pattern , it's base on a pattern, start from one corner, Switch to the opposite with a lot of direction change not very suitable for this technology. Don't realy see the benefits in this case .

From my point of view if you really want to occupy your rainy days the integration of decorative geometric patterns as on the example below would really be a solution that would interest many peoples (not me) but all those who make decorative boxes with their printers. Here the demand is strong and recurrent (just my point of view)

Sorry I just have a video Youtube in french for that, but don't need to listen the explanation to understand how it works. https://www.youtube.com/watch?v=N6GVV8fklZA

Thank you! I will try it! :)

I can see how this could produce a decorative effect when using translucent filament...
