git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@726 bbaffbd6-741e-11dd-a85d-61de82d9cad9

added support for the multiprocessing module (uses multiple processes for calculating ContourFollow toolpaths)


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@725 bbaffbd6-741e-11dd-a85d-61de82d9cad9

git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@724 bbaffbd6-741e-11dd-a85d-61de82d9cad9

fixed typo
fixed another floating point inaccuracy issue
replaced full function definitions for "ceil", "sqrt" and "number" with lambda inline functions


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@723 bbaffbd6-741e-11dd-a85d-61de82d9cad9

fix floating inaccuracy problem in ContourFollow
added string representation for Bounds instances

pre-select output filenames for "Save as" dialogs based on the model's filename


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@719 bbaffbd6-741e-11dd-a85d-61de82d9cad9

disabled code for adding comments to the STL files
fixed two sample STL files with wrong order of vertices


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@718 bbaffbd6-741e-11dd-a85d-61de82d9cad9

ContourFollow should use SimpleCutter instead of PathAccumulator (since it is a slice based algorithm)


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@717 bbaffbd6-741e-11dd-a85d-61de82d9cad9

fixed order of points when creating a support grid (this fixes the normal's and thus finally fixes collision detection)


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@716 bbaffbd6-741e-11dd-a85d-61de82d9cad9

improve results for non-cylindrical cutter
avoid ambiguous collision checks starting from an endpoint of a possible outer_edge


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@715 bbaffbd6-741e-11dd-a85d-61de82d9cad9

git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@714 bbaffbd6-741e-11dd-a85d-61de82d9cad9

ignore only triangles for further processing if the triangle is completely above the current cutter location

git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@712 bbaffbd6-741e-11dd-a85d-61de82d9cad9

don't transform the edges of a triangle during a rotation/shifting - they are re-calculated afterwards anyway
 * this should improve the performance of model transformations significantly
fixed the order of the vertices for OpenGL: a counter-clockwise order is expected


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@711 bbaffbd6-741e-11dd-a85d-61de82d9cad9

fixed the generation of the triangle's normal (in case they are undefined or badly formatted) during import (they pointed at the inside of the model before)
fixed the order of vertices when creating a new Triangle instance (clockwise instead of STL's counter-clockwise order is expected)
output a warning once if the direction of the normal does not match the order of the vertices of a triangle (both indicators are redundant and should be consistent)


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@710 bbaffbd6-741e-11dd-a85d-61de82d9cad9

fixed the removal of previous "time estimation" lines in the progress control text by using a proper string comparision (instead of simply removing the last line of the previous text)


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@709 bbaffbd6-741e-11dd-a85d-61de82d9cad9

fixed name of cut sphere


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@708 bbaffbd6-741e-11dd-a85d-61de82d9cad9

remember triangles that do not result in a valid collision

increased the shifting distance slightly to avoid "touches"
added DEBUG flags
added the logging facility


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@700 bbaffbd6-741e-11dd-a85d-61de82d9cad9

prevent each collision detection code to be triggered by a "touch" (this avoids problems with float inaccuracies)


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@699 bbaffbd6-741e-11dd-a85d-61de82d9cad9

fixed result of "get_free_paths_triangle" for non-collisions (return start and end point instead of nothing)
added representation of Hit objects
simplified forward/backward calculation


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@698 bbaffbd6-741e-11dd-a85d-61de82d9cad9
