circular, convex, concave) and performs efficient collision detection agains these build
volumes. As of now, collision detection is performed against a convex
hull of a concave build volume for efficency.
GCodeProcessor::Result renamed out of GCodeProcessor to GCodeProcessorResult,
so it could be forward declared.
Plater newly exports BuildVolume, not Bed3D. Bed3D is a rendering class,
while BuildVolume is a purely geometric class.
Reduced usage of global wxGetApp, the Bed3D is passed as a parameter
to View3D/Preview/GLCanvas.
Convex hull code was extracted from Geometry.cpp/hpp to Geometry/ConvexHulll.cpp,hpp.
New test inside_convex_polygon().
New efficent point inside polygon test: Decompose convex hull
to bottom / top parts and use the decomposition to detect point inside
a convex polygon in O(log n). decompose_convex_polygon_top_bottom(),
inside_convex_polygon().
New Circle constructing functions: circle_ransac() and circle_taubin_newton().
New polygon_is_convex() test with unit tests.
round() rounds to an integer.
This is a popular request, for example #3472
digits(value, num_digits, num_decimals) rounds to num_digits and
num_decimals, left filled with spaces.
digits(value, num_digits) the same as digits(value, num_digits, 0)
Neither decimal separator nor any decimals after decimal separator
are emitted.
zdigits(...) is the same as digits(...) only left filled with zeros.
If the result does not fit num_digits, the result is never trimmed.
for offset2() with clear meaning.
New ClipperUtils functions: expand(), shrink() as an alternative
for offset() with clear meaning.
All offset values for the new functions are positive.
Various offsetting ClipperUtils (offset, offset2, offset2_ex) working
over Polygons were marked as unsafe, sometimes producing invalid output
if called for more than one polygon. These functions were reworked
to offset polygons one by one. The new functions working over Polygons
shall work the same way as the old safe ones working over ExPolygons,
but working with Polygons shall be computationally more efficient.
Improvements in FDM support generator:
1) For both grid and snug supports: Don't filter out supports for which
the contacts are completely reduced by support / object XY separation.
2) Rounding / merging of supports using the closing radius parameter is
now smoother, it does not produce sharp corners.
3) Snug supports: When calculating support interfaces, expand the projected
support contact areas to produce wider, printable and more stable interfaces.
4) Don't reduce support interfaces for snug supports for steep overhangs,
that would normally not need them. Snug supports often produce very
narrow support interface regions and turning them off makes the support
interfaces disappear.
TriangleMesh newly only holds indexed_triangle_set and
TriangleMeshStats. TriangleMeshStats contains an excerpt of stl_stats.
TriangleMeshStats are updated when initializing with indexed_triangle_set.
Admesh triangle mesh fixing is newly only used when loading an STL.
AMF / 3MF / OBJ file formats are already indexed triangle sets, thus
they are no more converted to admesh stl_file format, nor fixed
through admesh repair machinery. When importing AMF / 3MF / OBJ files,
volume is calculated and if negative, all faces are flipped. Also
a bounding box and number of open edges is calculated.
Implemented its_number_of_patches(), its_num_open_edges()
Optimized its_split(), its_is_splittable() using a visitor pattern.
Reworked QHull integration into TriangleMesh:
1) Face normals were not right.
2) Indexed triangle set is newly emitted instead of duplicating
vertices for each face.
Fixed cut_mesh(): Orient the triangulated faces correctly.
