* Implement NV_path_rendering on OpenGL ESGravatar kkinnunen2014-08-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement support for NV_path_rendering on OpenGL ES. Use glProgramPathFragmentInputGenNV function call instead of glPathTexGenNV to communicate transforms to fragment shader. The intention is that the NVPR paths will be drawn with the same shader program as non-NVPR geometry. For NVPR calls, the GPU will skip the vertex shader and just run the fragment shader. After program is linked, query the locations of the fragment shader inputs with glGetResourceLocation. The location will be used to set the transforms with glProgramPathFragmentInputGenNV. The functions and their workings are documented in: glProgramPathFragmentInputGenNV https://www.opengl.org/registry/specs/NV/path_rendering.txt (note: addition as of API version 1.3) glGetResourceLocation https://www.opengl.org/registry/specs/ARB/program_interface_query.txt http://www.opengl.org/registry/doc/glspec44.core.pdf (function is in core Open GL 4.4) Note: glProgramPathFragmentInputGenNV could be used also for OpenGL. However, using seems to trigger a bug in the driver. Disable this feature on OpenGL at least until the driver is fixed and released. The bug manifests in shadertext test, where the lower-left text pair is missing. Valgrind catches a bad read for the test and causes the context to OOM reproducibly.

* Make GrGLProgram be available to GrGLProgramDataManagerGravatar kkinnunen2014-08-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GL APIs such as glProgramPathFragmentInputGenNV need the explicit program id in order to set the program resources. For GrGLProgramDataManager to call the APIs, the program id needs to be available to the GrGLProgramDataManager. One GrGLProgramDataManager is used to explicitly manage the resources of one GrGLProgram. Refactor the classes to reflect this: make GrGLProgram create and own GrGLProgramDataManager. This way the program id can be made available through GrGLProgram backpointer. In order to do this, remove the population of the program link results information for uniforms in GrGLProgramDataManager during shader generation. Instead, accumulate the info to the uniform list of GrGLShaderBuilder. After the generation, compilation and link is successful, this info can be used to construct both GrGLProgram and GrGLProgramDataManager. Changes names of functions to create UniformHandles and convert them to list indices. This tries to highlight that they're different lists, even though at the moment they match index-wise. E.g the contract is that handles can be created based on the shader builder state, and the object can later be set with the handle and the manager that was created with the builder. This is needed to support NV_path_rendering for GLES. R=bsalomon@google.com Author: kkinnunen@nvidia.com Review URL: https://codereview.chromium.org/426553011

* Please Valgrind by calling preConcat.Gravatar commit-bot@chromium.org2014-03-28
| | | | | | | | | | | | | | | | | | | Valgrind's whining about m.setConcat(m, I). That special cases into m = m, which compiles into memcpy(&m, &m, sizeof(m)), and then Valgrind decides that's not kosher because &m and &m overlap. (memmove would have been fine, but this is compiler generated code; not much we can do.) preConcat gets us the same thing with an early can-we-noop check for I, sidestepping the whole problem.

* Implement SkColorFilter as a GrGLEffectGravatar commit-bot@chromium.org2013-10-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds GrEffect::willUseInputColor() which indicates whether or not the input color affects the output of the effect. This is needed for certain Xfermodes, such as kSrc_Mode. For these modes the color filter will not use the input color. An effect with GrEffect::willUseInputColor() true will cause all color or coverage effects before it to be discarded, as their computations cannot affect the output. In these cases program is marked as having white input color. This fixes an assert when Skia is compiled in a mode that prefers using uniforms instead of attributes for constants. (Flags GR_GL_USE_NV_PATH_RENDERING or GR_GL_NO_CONSTANT_ATTRIBUTES). Using attributes hides the problem where the fragment shader does not need input color for color filters that ignore DST part of the filter. The assert would be hit when uniform manager tries to bind an uniform which has been optimized away by the shader compiler. Adds specific GrGLSLExpr4 and GrGLSLExpr1 classes. This way the GLSL expressions like "(v - src.a)" can remain somewhat readable in form of "(v - src.a())". The GrGLSLExpr<typename> template implements the generic functionality, GrGLSLExprX is the specialization that exposes the type-safe interface to this functionality. Also adds operators so that GLSL binary operators of the form "(float * vecX)" can be expressed in C++. Before only the equivalent "(vecX * float)" was possible. This reverts the common blending calculations to more conventional order, such as "(1-a) * c" instead of "c * (1-a)". Changes GrGLSLExpr1::OnesStr from 1 to 1.0 in order to preserve the color filter blending formula string the same (with the exception of variable name change). Shaders change in case of input color being needed: - vec4 filteredColor; - filteredColor = (((1.0 - uFilterColor.a) * output_Stage0) + uFilterColor); - fsColorOut = filteredColor; + vec4 output_Stage1; + { // Stage 1: ModeColorFilterEffect + output_Stage1 = (((1.0 - uFilterColor_Stage1.a) * output_Stage0) + uFilterColor_Stage1); + } + fsColorOut = output_Stage1; Shaders change in case of input color being not needed: -uniform vec4 uFilterColor; -in vec4 vColor; +uniform vec4 uFilterColor_Stage0; out vec4 fsColorOut; void main() { - vec4 filteredColor; - filteredColor = uFilterColor; - fsColorOut = filteredColor; + vec4 output_Stage0; + { // Stage 0: ModeColorFilterEffect + output_Stage0 = uFilterColor_Stage0; + } + fsColorOut = output_Stage0; } R=bsalomon@google.com, robertphillips@google.com, jvanverth@google.com Author: kkinnunen@nvidia.com Review URL: https://codereview.chromium.org/25023003 git-svn-id: http://skia.googlecode.com/svn/trunk@11912 2bbb7eff-a529-9590-31e7-b0007b416f81

* Add a requiresVertexShader method to GrGLEffectGravatar commit-bot@chromium.org2013-09-06
| | | | | | | | | | | | | | | | Adds requiresVertexShader to GrGLEffect and updates the necessary effects to override it and return true. Also reworks GrGLProgram and GrGLShaderBuilder so the program creates all the GL effects at the beginning, and determines if it needs a vertex shader before creating the shader builder.

* Add getGLMatrix method to MatrixStateGravatar commit-bot@chromium.org2013-09-05
| | | | | | | | | | | | | Removes redundant code by consolidating it into a single method. No change in functionality, this is strictly a refactoring.

* Add a GrGpuGL reference for GrGLProgram/GrGLUniformManagerGravatar commit-bot@chromium.org2013-09-05
| | | | | | | | | | | | | | | Updates GrGLProgram and GrGLUniformManager to keep a GrGpuGL reference instead of one for GrGLContextInfo. No change in functionality, this is in preparation to support fixed function GL calls for vertexless shaders.

* Isolate VertexBuilder from GrGLShaderBuilderGravatar commit-bot@chromium.org2013-08-30
| | | | | | | | | | | | | | | Adds a nested class to GrGLShaderBuilder called VertexBuilder. Now GrGLShaderBuilder can only modify the fragment shader directly. In order to modify the vertex shader, the client code needs to call getVertexShader, which will return null for vertex-less shaders.

* Refactor GrGLUniformManager::UniformHandle to initialize itself by defaultGravatar commit-bot@chromium.org2013-08-14
| | | | | | | | | | | | | | | | | | | | Refactor GrGLUniformManager::UniformHandle to initialize itself to "invalid" state by default. This simplifies the effect constructors. In the future, it should also help catch potential uninitialized uniform variable usage. Remove unneeded explicit uniform handle validity assertions before the handle usage. The assertion will always be made when handle is converted to index.
