* only call scalar finite when necessaryGravatar caryclark2015-12-16
| | | | | | | | | | | | | | | | | Mike points that the the ulps compares rank high in path ops profiles. The check for finite scalars is rarely required. Call it less by: - specializing _pin version of compares - checking for 0 divides up front - handling failing cases before comparing - casting float to double before adding R=reed@google.com Review URL: https://codereview.chromium.org/1522183002

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.

| | | | | | | | | | | | | | | | | | Replace SkTDArray with SkTArray and use SkSTArray when the probable array size is known. In a couple of places (spans, chases) the arrays are constructed using insert() so SkTArrays can't be used for now. Also, add an optimization to cubic subdivide if either end is zero or one.

* 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.
