* 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

* Express (GLSL expression, possibly known value) pairs as a classGravatar commit-bot@chromium.org2013-10-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Express (GLSL expression, possibly known value) pairs as a class instead of two variables Introduces GrGLSLExpr<N> to encapsulate the expression and possibly constant-folded value of the expression. This simplifies passing of the expressions to functions. Changes the shaders with following patterns: { // Stage 0: Linear Gradient vec4 colorTemp = mix(uGradientStartColor_Stage0, uGradientEndColor_Stage0, clamp(vMatrixCoord_Stage0.x, 0.0, 1 colorTemp.rgb *= colorTemp.a; - output_Stage0 = vec4((vColor) * (colorTemp)); + output_Stage0 = (vColor * colorTemp); + } Previously the vector cast was always added if constant folding was effective, regardless of the term dimensions. Now the vector upcast is not inserted in places where it is not needed, ie. when the binary operator term is of the target dimension. Also, some parentheses can be omitted. It is assumed that GrGLSLExpr<N>("string") constructors construct a simple expression or parenthesized expression. Otherwise the shader code remains identical.

* Move VertexBuilder to a GrGLFullShaderBuilder subclassGravatar commit-bot@chromium.org2013-10-04
| | | | | | | | | | | | | | | | | | | Removes the VertexBuilder nested class from GrGLShaderBuilder in favor of a new GrGLFullShaderBuilder subclass, and adds an optional emitCode overload to GrGLEffect that takes a GrGLFullShaderBuilder. Makes setData virtual in GrGLEffectArray and adds a GrGLVertexEffectArray subclass that gets built using a GrGLFullShaderBuilder. Also adds a new GrGLVertexEffect subclass that makes the GrGLFullShaderBuilder overload required for emitCode, and updates GrGLEffects to inherit from GrGLVertexEffect where needed.
