* Mike R: please sanity check SkPostConfig.hGravatar commit-bot@chromium.org2014-04-14
| | | | | | | | | | | | | | | | | | | | | | | | Mike K: please sanity check Test.cpp and skia_test.cpp Feel free to look at the rest, but I don't expect any in depth review of path ops innards. Path Ops first iteration used QuickSort to order segments radiating from an intersection to compute the winding rule. This revision uses a circular sort instead. Breaking out the circular sort into its own long-lived structure (SkOpAngle) allows doing less work and provides a home for caching additional sorting data. The circle sort is more stable than the former sort, has a robust ordering and fewer exceptions. It finds unsortable ordering less often. It is less reliant on the initial curve tangent, using convex hulls instead whenever it can. Additional debug validation makes sure that the computed structures are self-consistent. A new visualization tool helps verify that the angle ordering is correct. The 70+M tests pass with this change on Windows, Mac, Linux 32 and Linux 64 in debug and release.

| | | | | | | | | | | | | | | Remove unused code from SkOpSegment.cpp and friends. Add new tests exposed by coverage. Fix a bug exposed by coverage -- removing the need to detect points that are nearby when intersecting. Add gyp rule for building coverage flavor on Mac.

* path ops -- rewrite angle sortGravatar caryclark@google.com2013-06-04
| | | | | | | | | | | | | | | | | | | | | | | | This is a major change resulting from a minor tweak. In the old code, the intersection point of two curves was shared between them, but the intersection points and end points of sorted edges was computed directly from the intersection T value. In this CL, both intersection points and sorted points are the same, and intermediate control points are computed to preserve their slope. The sort itself has been completely rewritten to be more robust and remove 'magic' checks, conditions that empirically worked but couldn't be rationalized. This CL was triggered by errors generated computing the clips of SKP files. At this point, all 73M standard tests work and at least the first troublesome SKPs work.

* Add base types for path opsGravatar caryclark@google.com2013-04-08
Paths contain lines, quads, and cubics, which are collectively curves. To work with path intersections, intermediary curves are constructed. For now, those intermediates use doubles to guarantee sufficient precision. The DVector, DPoint, DLine, DQuad, and DCubic structs encapsulate these intermediate curves. The DRect and DTriangle structs are created to describe intersectable areas of interest. The Bounds struct inherits from SkRect to create a SkScalar-based rectangle that intersects shared edges. This also includes common math equalities and debugging that the remainder of path ops builds on, as well as a temporary top-level interface in include/pathops/SkPathOps.h.
