This header file may change from version to +// version without notice, or even be removed. +// +// We mean it. +// + +/* + VERTEX SHADERS + ============== + + Vertex shaders are specified as multiple (partial) shaders. On desktop, + this works fine. On ES, QOpenGLShader & QOpenGLShaderProgram will make partial + shaders work by concatenating the source in each QOpenGLShader and compiling + it as a single shader. This is abstracted nicely by QOpenGLShaderProgram and + the GL2 engine doesn't need to worry about it. + + Generally, there's two vertex shader objects. The position shaders are + the ones which set gl_Position. There's also two "main" vertex shaders, + one which just calls the position shader and another which also passes + through some texture coordinates from a vertex attribute array to a + varying. These texture coordinates are used for mask position in text + rendering and for the source coordinates in drawImage/drawPixmap. There's + also a "Simple" vertex shader for rendering a solid colour (used to render + into the stencil buffer where the actual colour value is discarded). + + The position shaders for brushes look scary. This is because many of the + calculations which logically belong in the fragment shader have been moved + into the vertex shader to improve performance. This is why the position + calculation is in a separate shader. Not only does it calculate the + position, but it also calculates some data to be passed to the fragment + shader as a varying. It is optimal to move as much of the calculation as + possible into the vertex shader as this is executed less often. + + The varyings passed to the fragment shaders are interpolated (which is + cheap). Unfortunately, GL will apply perspective correction to the + interpolation calusing errors. To get around this, the vertex shader must + apply perspective correction itself and set the w-value of gl_Position to + zero. That way, GL will be tricked into thinking it doesn't need to apply a + perspective correction and use linear interpolation instead (which is what + we want). Of course, if the brush transform is affeine, no perspective + correction is needed and a simpler vertex shader can be used instead. + + So there are the following "main" vertex shaders: + qopenglslMainVertexShader + qopenglslMainWithTexCoordsVertexShader + + And the the following position vertex shaders: + qopenglslPositionOnlyVertexShader + qopenglslPositionWithTextureBrushVertexShader + qopenglslPositionWithPatternBrushVertexShader + qopenglslPositionWithLinearGradientBrushVertexShader + qopenglslPositionWithRadialGradientBrushVertexShader + qopenglslPositionWithConicalGradientBrushVertexShader + qopenglslAffinePositionWithTextureBrushVertexShader + qopenglslAffinePositionWithPatternBrushVertexShader + qopenglslAffinePositionWithLinearGradientBrushVertexShader + qopenglslAffinePositionWithRadialGradientBrushVertexShader + qopenglslAffinePositionWithConicalGradientBrushVertexShader + + Leading to 23 possible vertex shaders + + + FRAGMENT SHADERS + ================ + + Fragment shaders are also specified as multiple (partial) shaders. The + different fragment shaders represent the different stages in Qt's fragment + pipeline. There are 1-3 stages in this pipeline: First stage is to get the + fragment's colour value. The next stage is to get the fragment's mask value + (coverage value for anti-aliasing) and the final stage is to blend the + incoming fragment with the background (for composition modes not supported + by GL). + + Of these, the first stage will always be present. If Qt doesn't need to + apply anti-aliasing (because it's off or handled by multisampling) then + the coverage value doesn't need to be applied. (Note: There are two types + of mask, one for regular anti-aliasing and one for sub-pixel anti- + aliasing.) If the composition mode is one which GL supports natively then + the blending stage doesn't need to be applied. + + As eash stage can have multiple implementations, they are abstracted as + GLSL function calls with the following signatures: + + Brushes & image drawing are implementations of "qcolorp vec4 srcPixel()": + qopenglslImageSrcFragShader + qopenglslImageSrcWithPatternFragShader + qopenglslNonPremultipliedImageSrcFragShader + qopenglslSolidBrushSrcFragShader + qopenglslTextureBrushSrcFragShader + qopenglslTextureBrushWithPatternFragShader + qopenglslPatternBrushSrcFragShader + qopenglslLinearGradientBrushSrcFragShader + qopenglslRadialGradientBrushSrcFragShader + qopenglslConicalGradientBrushSrcFragShader + NOTE: It is assumed the colour returned by srcPixel() is pre-multiplied + + Masks are implementations of "qcolorp vec4 applyMask(qcolorp vec4 src)": + qopenglslMaskFragmentShader + qopenglslRgbMaskFragmentShaderPass1 + qopenglslRgbMaskFragmentShaderPass2 + qopenglslRgbMaskWithGammaFragmentShader + + Composition modes are "qcolorp vec4 compose(qcolorp vec4 src)": + qopenglslColorBurnCompositionModeFragmentShader + qopenglslColorDodgeCompositionModeFragmentShader + qopenglslDarkenCompositionModeFragmentShader + qopenglslDifferenceCompositionModeFragmentShader + qopenglslExclusionCompositionModeFragmentShader + qopenglslHardLightCompositionModeFragmentShader + qopenglslLightenCompositionModeFragmentShader + qopenglslMultiplyCompositionModeFragmentShader + qopenglslOverlayCompositionModeFragmentShader + qopenglslScreenCompositionModeFragmentShader + qopenglslSoftLightCompositionModeFragmentShader + + + Note: In the future, some GLSL compilers will support an extension allowing + a new 'color' precision specifier.

In + addition it provides a rendering surface that can be painted on + with a QPainter, rendered to using native GL calls, or both. This + surface can be bound and used as a regular texture in your own GL + drawing code. By default, the QOpenGLFramebufferObject class + generates a 2D GL texture (using the \c{GL_TEXTURE_2D} target), + which is used as the internal rendering target. + + \bold{It is important to have a current GL context when creating a + QOpenGLFramebufferObject, otherwise initialization will fail.} + + OpenGL framebuffer objects and pbuffers (see + \l{QOpenGLPixelBuffer}{QOpenGLPixelBuffer}) can both be used to render to + offscreen surfaces, but there are a number of advantages with + using framebuffer objects instead of pbuffers: + + \list 1 + \o A framebuffer object does not require a separate rendering + context, so no context switching will occur when switching + rendering targets. There is an overhead involved in switching + targets, but in general it is cheaper than a context switch to a + pbuffer. + + \o Rendering to dynamic textures (i.e. render-to-texture + functionality) works on all platforms. No need to do explicit copy + calls from a render buffer into a texture, as was necessary on + systems that did not support the \c{render_texture} extension. + + \o It is possible to attach several rendering buffers (or texture + objects) to the same framebuffer object, and render to all of them + without doing a context switch. + + \o The OpenGL framebuffer extension is a pure GL extension with no + system dependant WGL, CGL, or GLX parts. This makes using + framebuffer objects more portable. + \endlist + + When using a QPainter to paint to a QOpenGLFramebufferObject you should take + care that the QOpenGLFramebufferObject is created with the CombinedDepthStencil + attachment for QPainter to be able to render correctly. + Note that you need to create a QOpenGLFramebufferObject with more than one + sample per pixel for primitives to be antialiased when drawing using a + QPainter. To create a multisample framebuffer object you should use one of + the constructors that take a QOpenGLFramebufferObject parameter, and set the + QOpenGLFramebufferObject::samples() property to a non-zero value. + + When painting to a QOpenGLFramebufferObject using QPainter, the state of + the current GL context will be altered by the paint engine to reflect + its needs. Applications should not rely upon the GL state being reset + to its original conditions, particularly the current shader program, + GL viewport, texture units, and drawing modes. + + For multisample framebuffer objects a color render buffer is created, + otherwise a texture with the specified texture target is created. + The color render buffer or texture will have the specified internal + format, and will be bound to the \c GL_COLOR_ATTACHMENT0 + attachment in the framebuffer object. + + If you want to use a framebuffer object with multisampling enabled + as a texture, you first need to copy from it to a regular framebuffer + object using QOpenGLContext::blitFramebuffer(). + + \section1 Threading + + As of Qt 4.8, it's possible to draw into a QOpenGLFramebufferObject + using a QPainter in a separate thread.

The recommended way to use QOpenGLFunctions is by + direct inheritance: + + \code + class MyGLWidget : public QOpenGLWidget, protected QOpenGLFunctions + { + Q_OBJECT + public: + MyGLWidget(QWidget *parent = 0) : QOpenGLWidget(parent) {} + + protected: + void initializeGL(); + void paintGL(); + }; + + void MyGLWidget::initializeGL() + { + initializeGLFunctions(); + } + \endcode + + The \c{paintGL()} function can then use any of the OpenGL/ES 2.0 + functions without explicit resolution, such as glActiveTexture() + in the following example: + + \code + void MyGLWidget::paintGL() + { + glActiveTexture(GL_TEXTURE1); + glBindTexture(GL_TEXTURE_2D, textureId); + ... + } + \endcode + + QOpenGLFunctions can also be used directly for ad-hoc invocation + of OpenGL/ES 2.0 functions on all platforms: + + \code + QOpenGLFunctions glFuncs(QOpenGLContext::currentContext()); + glFuncs.glActiveTexture(GL_TEXTURE1); + \endcode + + QOpenGLFunctions provides wrappers for all OpenGL/ES 2.0 functions, + except those like \c{glDrawArrays()}, \c{glViewport()}, and + \c{glBindTexture()} that don't have portability issues. + + Including the header for QOpenGLFunctions will also define all of + the OpenGL/ES 2.0 macro constants that are not already defined by + the system's OpenGL headers, such as \c{GL_TEXTURE1} above. + + The hasOpenGLFeature() and openGLFeatures() functions can be used + to determine if the OpenGL implementation has a major OpenGL/ES 2.0 + feature. For example, the following checks if non power of two + textures are available: + + \code + QOpenGLFunctions funcs(QOpenGLContext::currentContext()); + bool npot = funcs.hasOpenGLFeature(QOpenGLFunctions::NPOTTextures); + \endcode +*/ + +/*! + \enum QOpenGLFunctions::OpenGLFeature + This enum defines OpenGL/ES 2.0 features that may be optional + on other platforms. + + \value Multitexture glActiveTexture() function is available. + \value Shaders Shader functions are available. + \value Buffers Vertex and index buffer functions are available. + \value Framebuffers Framebuffer object functions are available. + \value BlendColor glBlendColor() is available. + \value BlendEquation glBlendEquation() is available. + \value BlendEquationSeparate glBlendEquationSeparate() is available. + \value BlendFuncSeparate glBlendFuncSeparate() is available. + \value BlendSubtract Blend subtract mode is available. + \value CompressedTextures Compressed texture functions are available. + \value Multisample glSampleCoverage() function is available. + \value StencilSeparate Separate stencil functions are available. + \value NPOTTextures Non power of two textures are available. +*/ + +// Hidden private fields for additional extension data. +struct QOpenGLFunctionsPrivateEx : public QOpenGLExtensionsPrivate, public QOpenGLSharedResource +{ + QOpenGLFunctionsPrivateEx(QOpenGLContext *context) + : QOpenGLExtensionsPrivate(context) + , QOpenGLSharedResource(context->shareGroup()) + , m_features(-1) + , m_extensions(-1) + {} + + void invalidateResource() + { + m_features = -1; + m_extensions = -1; + } + + void freeResource(QOpenGLContext *) + { + // no gl resources to free + } + + int m_features; + int m_extensions; +}; + +Q_GLOBAL_STATIC(QOpenGLMultiGroupSharedResource, qt_gl_functions_resource) + +static QOpenGLFunctionsPrivateEx *qt_gl_functions(QOpenGLContext *context = 0) +{ + if (!context) + context = QOpenGLContext::currentContext(); + Q_ASSERT(context); + QOpenGLFunctionsPrivateEx *funcs = + qt_gl_functions_resource()->value(context); + return funcs; +} + +/*! + Constructs a default function resolver.

In particular, GLSL/ES lacks all of the + standard variables that are present on desktop OpenGL systems: + \c{gl_Vertex}, \c{gl_Normal}, \c{gl_Color}, and so on. Desktop OpenGL + lacks the variable qualifiers \c{highp}, \c{mediump}, and \c{lowp}. + + The QOpenGLShaderProgram class makes the process of writing portable shaders + easier by prefixing all shader programs with the following lines on + desktop OpenGL: + + \code + #define highp + #define mediump + #define lowp + \endcode + + This makes it possible to run most GLSL/ES shader programs + on desktop systems.
