SupportSpotsGenerator originally used a heuristic formula. Current
formula is properly derived using known properties of
second moment of area. Several tests of this formula are added.
WIP GCode/SmoothPath.cpp,hpp cache for interpolating extrusion path with arches.
Removed Perl test t/geometry.t, replaced with C++ tests.
Refactored ExtrusionEntity and derived classes to hold extrusion attributes in new ExtrusionFlow/ExtrusionAttributes classes.
Reworked path ordering in G-code export to never copy polylines, but to work with a new "flipped" attribute.
Reworked G-code export to interpolate extrusion paths with smooth paths and to extrude those smooth paths.
New parameters: arc_fitting, arc_fitting_tolerance
Renamed GCode class to GCodeGenerator
Moved GCodeWriter.cpp/hpp to GCode/
Moved Wipe from from GCode.cpp,hpp to GCode/Wipe.cpp,hpp
Moved WipeTowerIntegration from GCode.cpp,hpp to GCode/WipeTowerIntegration.cpp,hpp
New variant of douglas_peucker() to simplify range of iterators in place.
Refactored wipe in general and wipe on perimeters / hiding seams.
WIP: Convert estimate_speed_from_extrusion_quality() and its application to smooth paths.
WIP: Cooling buffer to process G2G3, disable arc fitting for filters that cannot process it.
Boost Voronoi diagram produced degenerated Voronoi diagram. This Voronoi diagram was detected by our method for detection of those types of degeneration. But rotation by PI / 6 wasn't able to fix it.
So now, when the Voronoi diagram is still degenerated after the first rotation, then we try another rotation by different angles to fix the degenerated Voronoi diagram.
{if condition then block elsif}
The "then" keyword is now mandatory.
On the other hand, "then" keyword must NOT be used using old syntax:
{if condition}...{endif}
{if cond1}{expr1}{elsif cond2}{expr2}{else}{expr3}{endif}
could be written as
{if cond1;expr1;elsif cond2;expr2;else;expr3;endif}
the first semicolon after else is not manadtory, thus the following is valid
{if cond1;expr1;elsif cond2;expr2;else expr3;endif}
each expression could be also empty or contain multiple expressions:
{if cond1;elsif cond2;else endif}
Implements #4048#7196
Syntax:
(global|local) variable_name =
(scalar_expression|vector_variable|array_expr|initializer_list)
array_expr := array(repeat, value)
initializer_list := (value, value, value, ...)
The type of the newly created variable is defined by the type
of the right hand side intitializer.
Newly declared variable must not override an existing variable.
Variable may be assigned with global|local expression, but its type
must not be changed.
Newly the assignment operator also accepts the same right hand expressions
as the global|local variable definition.
1st parameter is the text to match against,
the rest of the parameters are pattern to be matched:
either strings, then the match is exact,
or regex enclosed in //
or regex string starting with ~
For example
one_of("a", "a", "b")
finds a in "a", "b"
one_of("abc", /.*a.*/)
matches "abc" using regular expression /.*a.*/
