* Now, path ops natively intersect conics, quads, and cubics in any ↵Gravatar caryclark2015-04-20
| | | | | | | | | | | combination. There are still a class of cubic tests that fail and a handful of undiagnosed failures from skps and fuzz tests, but things are much better overall. Extended tests (150M+) run to completion in release in about 6 minutes; the standard test suite exceeds 100K and finishes in a few seconds on desktops.

* cumulative pathops patchGravatar caryclark2015-03-26
| | | | | | | | | | | | | | | | | | | | | Replace the implicit curve intersection with a geometric curve intersection. The implicit intersection proved mathematically unstable and took a long time to zero in on an answer. Use pointers instead of indices to refer to parts of curves. Indices required awkward renumbering. Unify t and point values so that small intervals can be eliminated in one pass. Break cubics up front to eliminate loops and cusps. Make the Simplify and Op code more regular and eliminate arbitrary differences. Add a builder that takes an array of paths and operators. Delete unused code.

* Fix last pathops skp bugGravatar caryclark2014-06-18
| | | | | | | | | | | | | | | | | | | | | | This fixes the last bug discovered by iterating through the 800K skp corpus representing the top 1M websites. For every clip on the stack, the paths are replaced with the pathop intersection. The resulting draw is compared with the original draw for pixel errors. At least two prominent bugs remain. In one, the winding value is confused by a cubic with an inflection. In the other, a quad/cubic pair, nearly coincident, fails to find an intersection. These minor changes include ignoring very tiny self-intersections of cubics, and processing degenerate edges that don't connect to anything else.

* Enabling the canvas bit to turn the clip stack into a flat replace exposed ↵Gravatar caryclark2014-06-17
| | | | | | | | | | | | | | | | | | around 100 failures when testing the 800K skp set generated from the top 1M web sites. This fixes all but one of those failures. Major changes include: - Replace angle indices with angle pointers. This was motivated by the need to add angles later but not renumber existing angles. - Aggressive segment chase. When the winding is known on a segment, more aggressively passing that winding to adjacent segments allows fragmented data sets to succeed. - Line segments with ends nearly the same are treated as coincident first. - Transfer partial coincidence by observing that if segment A is partially coincident to B and C then B and C may be partially coincident.

* When solving the cubic line intersection directly fails, use binary search ↵Gravatar commit-bot@chromium.org2014-05-07

The cubic line intersection math empirically works 99.99% of the time (fails 3100 out of 1B random tests) but when it fails, an intersection may be missed altogether. The binary search is may not find a solution if the cubic line failed to find any solutions at all, but so far that case hasn't arisen.

| | | | | | | | | | | | | | | | | | | | | | | | 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.
