* Replace SkFAIL with SK_ABORT.Gravatar Ben Wagner2017-08-16
| | | | | | | | | | | | SkFAIL is a legacy macro which is just SK_ABORT. This CL mechanically changes uses of SkFAIL to SK_ABORT in preparation for its removal. The related sk_throw macro will be changed independently, due to needing to actually clean up its users.

* Refactor to separate backend object lifecycle and GpuResource budget decisionGravatar kkinnunen2016-04-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Refactor GrGpuResource to contain two different pieces of state: a) instance is budgeted or not budgeted b) instance references wrapped backend objects or not The "object lifecycle" was also attached to backend object handles (ids), which made the code a bit unclear. Backend objects would be associated with GrGpuResource::LifeCycle, even though GrGpuResource::LifeCycle refers to the GpuResource, and individual backend objects in one GpuResource might be governed with different "lifecycle". Mark the budgeted/not budgeted with SkBudgeted::kYes, SkBudgeted::kNo. This was previously GrGpuResource::kCached_LifeCycle, GrGpuResource::kUncached_LifeCycle. Mark the "references wrapped object" with boolean. This was previously GrGpuResource::kBorrowed_LifeCycle, GrGpuResource::kAdopted_LifeCycle for GrGpuResource. Associate the backend object ownership status with GrBackendObjectOwnership for the backend object handles. The resource type leaf constuctors, such has GrGLTexture or GrGLTextureRenderTarget take "budgeted" parameter. This parameter is passed to GrGpuResource::registerWithCache(). The resource type intermediary constructors, such as GrGLTexture constructors for class GrGLTextureRenderTarget do not take "budgeted" parameters, intermediary construtors do not call registerWithCache. Removes the need for tagging GrGpuResource -derived subclass constructors with "Derived" parameter. Makes instances that wrap backend objects be registered with a new function GrGpuResource::registerWithCacheWrapped(). Removes "budgeted" parameter from classes such as StencilAttahment, as they are always cached and never wrap any external backend objects. Removes the use of concept "external" from the member function names. The API refers to the objects as "wrapped", so make all related functions use the term consistently. No change in functionality. Resources referencing wrapped objects are always inserted to the cache with budget decision kNo. BUG=594928 GOLD_TRYBOT_URL= https://gold.skia.org/search2?unt=true&query=source_type%3Dgm&master=false&issue=1862043002 Review URL: https://codereview.chromium.org/1862043002

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Set the "path stroke error bound" path parameter to 0.02 for all paths. This means that the stroked path area will be within 98% of the stroke width in path space. This should fix many cases where NVPR stroked paths were visibly different to Skia stroked paths. One such path is in dashcubics gm. This increases the amount of subdivisions the path object creation will make for paths that need it. This in turn will increase gpu object space requirements sligthly. Both of these effects should be unnoticeable. GL_NV_path_rendering.txt: """ Every path object has a stroke approximation bound parameter (PATH_STROKE_BOUND_NV) that is a floating-point value /sab/ clamped between 0.0 and 1.0 and set and queried with the PATH_STROKE_BOUND_NV path parameter. Exact determination of samples swept an orthogonal centered line segment along cubic Bezier segments and rational quadratic Bezier curves (so non-circular partial elliptical arcs) is intractable for real-time rendering so an approximation is required; /sab/ intuitively bounds the approximation error as a percentage of the path object's stroke width. Specifically, this path parameter requests the implementation to stencil any samples within /sweep/ object space units of the exact sweep of the path's cubic Bezier segments or partial elliptical arcs to be sampled by the stroke where sweep = ((1-sab)*sw)/2 where /sw/ is the path object's stroke width. The initial value of /sab/ when a path is created is 0.2. In practical terms, this initial value means the stencil sample positions coverage within 80% (100%-20%) of the stroke width of cubic and rational quadratic stroke segments should be sampled.

| | | | | | | | | | | | | | | | | | | | | | | Simplify GrGLPathRendering interface by removing polymorphism and functions that simply wrap GL functions unnecessarily. Replace the polymorphism by if -condition. Call the unconditional GL functions directly. GrGLPath, GrGLPathRange and GrGLPathRendering are part of the same logical subsystem. This means that the subsystem implementation details are taken into account within these classes. Example: if support for using conics would be added, the feature flag would go to GrGLPathRendering::Caps, the emulation would go to GrGLPath instead of GrGLPathRendering::pathCommands. Wrapping glPathCommandsNV is not useful. Try to expose the interface fully in same logical level; rename fragment input function to reflect this.

Try to reduce this cost by caching paths based on the SkPath "hash" (i.e. SkPathRef generation id) and stroke properties. Adds the paths to GrContext::fTextureCache instance. Later this should be renamed and the GrContext API should reflect the nature of the cache better.

* Implement stroking a path with nv_path_renderingGravatar commit-bot@chromium.org2013-10-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | Initialize the path stroke properties in the GrGLPath constructor. Use StencilStrokePath and CoverStrokePath to stroke the path. The order of the GL calls is: 1. StencilFill, if needed 2. StencilStroke, if needed 2a. CoverStroke, if stroke was applied 2b. CoverFill, if stroke was not applied The reason for not pairing StencilFill + CoverFill, StencilStroke + CoverStroke is that Skia API does not allow separate fill and stroke color within one call. Covering the stroke bounding box should also cover the fill bounding box. Causes different rendering in gm/dashcubics due to different rendering algorithm. (?) (TODO: this should be resolved somehow.)

* Fix a crash on stroking empty paths with nv_path_rendering enabledGravatar commit-bot@chromium.org2013-08-05
| | | | | | | | | | | | | | | | Fix the crash by defining that GrPathRenderer::drawPath and GrPathRenderer::stencilPath are called only with non-empty paths. Adds a new test "GpuDrawPath" and tests the condition.
