* Refactor shaders into seprate GLSL source filesSean Harmer2013-10-311-66/+10
| | | | | | | | | | | | | | | | | | | | | | The default implementation of QSGShaderMaterial::vertexShader() and fragmentShader() now loads the GLSL source from a list of source files that can be specified via the setShaderSourceFile() or setShaderSourceFiles() functions. Multiple shader source files for each shader stage are supported. Each source file will be read in the order specified and concatenated together before being compiled. The other places where Qt Quick 2 loads shader source code have been adapted to use the new QSGShaderSourceBuilder, which is also used internally by QSGMaterial. This puts Qt Quick 2 into a better state ready to support OpenGL core profile and to load different shaders based upon OpenGL version, profile, GPU vendor, platform, etc. Change-Id: I1a66213c2ce788413168eb48c7bc5317e61988a2 Reviewed-by: Gunnar Sletta <gunnar.sletta@digia.com>
* Prevent badly formed texture nodes in the scene graph.Gunnar Sletta2013-10-211-5/+3
| | | | | | | | | | | | | | | | | A texture based node without a valid texture is not allowed, as the material and the renderer will only tolerate well-formed nodes. If a node is missing any part of its material state it should not be in the scene graph in the first place. Because of an "optimization" in QSGDefaultImageNode::setTexture and QSGSimpleTextureNode::setTexture, we must temporarily set the texture to 0 to ensure that it gets updated properly. This temporarily puts the node into an invalid state which can lead to crashes when QSGNode::markDirty() reaches the renderer.

* Work around mis-optimisation on QNX/SGX in AA vertex shaderSean Harmer2012-09-261-4/+12
| | | | | | | | | | | | | | | | | | | | | | | | The new AA algorithm which is implemented in the vertex shader of SmoothColorMaterialShader and SmoothTextureMaterialShader exposes a driver bug in the glsl compiler/optimiser for the GPU used in the BlackBerry PlayBook. The bug results in the if (scale < 0.0) scale = 1.0 code always being executed even when the condition is false. This leads to massive corrupion of Image, Rectangle, and BorderImage elements when the antialiasing property is enabled. This commit works around the compiler bug by refactoring the vertex shader to explicitly include an else clause. The check for negative values is now performed on the numerator only as the denominator is dot(dir, dir) which is always positive (square of magnitude of dir vector). This gives the correct behaviour on all platforms (that I have access to). Change-Id: I236542c9b59ff2915e95cbd9300b442be316bba9 Reviewed-by: Samuel Rødal <samuel.rodal@digia.com>

* Say hello to QtQuick moduleKent Hansen2011-12-021-0/+293
This change moves the QtQuick 2 types and C++ API (including SceneGraph) to a new module (AKA library), QtQuick. 99% of this change is moving files from src/declarative to src/quick, and from tests/auto/declarative to tests/auto/qtquick2. The loading of QtQuick 2 ("import QtQuick 2.0") is now delegated to a plugin, src/imports/qtquick2, just like it's done for QtQuick 1. All tools, examples, and tests that use QtQuick C++ API have gotten "QT += quick" or "QT += quick-private" added to their .pro file. A few additional internal QtDeclarative classes had to be exported (via Q_DECLARATIVE_PRIVATE_EXPORT) since they're needed by the QtQuick 2 implementation. The old header locations (e.g. QtDeclarative/qquickitem.h) will still be supported for some time, but will produce compile-time warnings. (To avoid the QtQuick implementation using the compatibility headers (since QtDeclarative's includepath comes first), a few include statements were modified, e.g. from "#include <qsgnode.h>" to "#include <QtQuick/qsgnode.h>".) There's a change in qtbase that automatically adds QtQuick to the module list if QtDeclarative is used. Together with the compatibility headers, this should help reduce the migration pain for existing projects. In theory, simply getting an existing QtDeclarative-based project to compile and link shouldn't require any changes for now -- but porting to the new scheme is of course recommended, and will eventually become mandatory.
