* Fix support interface semantics and gap handling
Fix zero-gap interface detection and gap initialization for supports and raft.
Ensures correct top/bottom contact semantics and avoids relying on default zero gaps.
* Additional fixes and robustness improvements
Fix incorrect coupling between top and bottom support interface spacing and density, ensuring bottom interfaces use their own parameters for smoothing and toolpath generation.
Restore correct bottom interface generation for organic (tree) supports when a non-zero bottom Z gap is used, and preserve contacts even when base polygons are empty.
Improve robustness of organic support slicing by fixing layer index drift and guarding against degenerate polygon boolean operations.
* Typo and semantics fix
differnt_support_interface_filament -> different_support_interface_filament
soluble -> zero_top_z_gap
* Fix non organic tree bottom support interface generation
Slim tree bottom interface layer numbers were capped by the object's layer number beneath it.
Fixed by refactoring the generation algorithm.
* Fix non organic tree interlaced support generation
Deterministic local interlaced support layers generation for non-organic tree support
* Enable support interface multimaterial for non organic tree
Enables mixed-material support interface behavior for non organic tree support type.
* Fix tree support interface layer counts and contact handling
- Correct non‑organic tree top interface layer budgeting so gaps don’t consume a layer (N stays N).
- Remove the extra roof interface pass that was duplicating the 2nd layer.
- Organic tree: use only the lowest contact footprint and avoid extra bottom‑contact extrusion so interface count matches the user setting.
* Bugfixes (a lot)
Many, many bugs fixed, majority edge-case but still not playing by the rule.
Some of them:
- on multilevel base, on very small level variations the support was capped to the topmost level height
- non-organic tree had gaps for supports in a multilevel base situiation
- independent support layer height had issues with support interfaces (base support beneath bottom interface, top contact layer sometimes missing)
- organic tree had issues with small variation multi-level base
- organic tree support with zero top Z distance could overlap support-material and interface-material paths when separate materials were used
- many, many others (I lost track of them)
Fix support preview artifacts caused by incorrect gap subdivision
Support generation could sometimes split a gap into too many steps,
even when it should fit exactly into a single layer.
This was most noticeable when max_suport_layer_height was equal to
the print layer height (e.g. 0.2 mm).
This resulted in incorrect support layering and visible artifacts
in preview.
The issue was caused by floating-point precision, where values that
should be equal to the configured limit were treated as slightly larger.
Fix by biasing the subdivision calculation with EPSILON so near-equal
values are not split into extra steps.
Applied consistently to:
- SupportMaterial (normal supports)
- TreeSupportCommon (tree stepping)
- TreeSupport (layer creation)
1. speedup organic tree support by using parallel for intersection of bed area
jira: STUDIO-8451
2. add extra wall for hybrid tree support's tall branches
3. disable circle fitting for tree support. This feature produces inconsistent
circles for tree supports.
4. expose the option tree_support_branch_diameter_angle. Tree supports'
strength can be improved by increasing this value.
