* 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.

* 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

| | | | | | | | | | | | | | | | | | Extracts a GrCustomCoordsTextureEffect class from GrSimpleTextureEffect. This way there are no effects that can conditionally require a vertex shader. They either always need one or never do. Also removes kCustom_CoordsType from the CoordsType enum in GrEffect (that enum is really only meant for coords provided by the framework), and updates GrSimpleTextureEffect::TestCreate to make the effect with position as well, instead of just local coords.
