Port Z Anti-Aliasing from BambuStudio-ZAA (https://github.com/adob/BambuStudio-ZAA)
to OrcaSlicer. ZAA eliminates stair-stepping on curved and sloped top surfaces
by raycasting each extrusion point against the original 3D mesh and micro-adjusting
Z height to follow the actual surface geometry.
Key changes:
- Add ContourZ.cpp raycasting algorithm (~330 lines)
- Extend geometry with 3D support (Point3, Line3, Polyline3, MultiPoint3)
- Template arc fitting for 2D/3D compatibility
- Change ExtrusionPath::polyline from Polyline to Polyline3
- Add 5 ZAA config options (zaa_enabled, zaa_min_z, etc.)
- Add posContouring pipeline step in PrintObject
- Update GCode writer for 3D coordinate output
- Add ZAA settings UI in Print Settings > Quality
- Add docs/ZAA.md with usage and implementation details
ZAA is opt-in and disabled by default. When disabled, the slicing pipeline
is unchanged.
* Overhang perimeter handling
Updated code to handle overhang perimeters as an overhang and not as a bridge.
* Preparing to add curled extrusions identification
* Porting curling calculations from Prusa Slier 2.6.1
* Prototype 1 - slowdown extended to detect curled edges and further reduce speed
First prototype of the code submitted.
* Working prototype - 2
Code is now finally working - external perimeters are slowed down as needed when there is likelyhood of curling up.
ToDo:
1. Reslicing the model causes the algorithm not to run - need to find where this fails to trigger the call for this.
2. Slowdown of internal perimeters not working yet.
* Updated to use overhang wall speed instead of bridging speed for this algorithm
* Fixed bug in speed calculation and tweaked parameters for high speed printer
Fixed bug in speed calculation and tweaked parameters for high speed printer
* Attempting to fix "set started" not being set
* Parameter tweak after print tests
* Fixed estimation not running when model is re-sliced.
* Removing debug printf statements and fixed threading flag.
* Fixed threading
* Parameter tweaks following print tests
* Made this as an option in the GUI
* Reintroduced handling of bridges as per original design
* UI line toggling when option makes sense to be visible.
* Fixed bug in field visibility & made it default to off
* Code optimisation
