* Cleanup of shader building systemGravatar joshualitt2014-10-07
| | | | | | | | | | | | | | | | | this is a huge refactor and cleanup of the gl shader building system in Skia. The entire shader building pipeline is now part of GrGLProgramCreator, which takes a gp, and some fps, and creates a program.

* Implement text rendering with NVPRGravatar kkinnunen2014-06-24
| | | | | | | | | | | | | | | | | | | | | | | | Use path rendering to render the text from outlines if supported by the GPU. Implement this in GrStencilAndCoverTextContext by copying chunks of code from GrBitmapTextContext. The drawing is implemented with "instanced" path drawing functions. Moves the creation of the "main" text context from SkGpuDevice to the GrContext::createTextContext. This is done because the decision of which text renderer is optimal can be made only with the internal implementation-specific information of the context. Remove a windows assertion from SkScalerContext_GDI::getGDIGlyphPath. The GetGlyphOutlineW fails in fontmgr_match for the initial space char in the string " [700] ...". According to MSDN, this is a known problem. Just return that the glyph has no path data in these cases.

* 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
