* New scenegraph renderer and atlas textures.Gunnar Sletta2013-09-021-546/+0
| | | | | | | | | | | | | The renderer tries to batch primitives together where possible, isolate non-changing subparts of the scene from changing subparts and retain vertexdata on the GPU as much as possible. Atlas textures are crucial in enabling batching. The renderer and atlas texture are described in detail in the doc page "Qt Quick Scene Graph Renderer".

* Support opt-in QSGNode descriptions without breaking binary compat.Gunnar Sletta2013-08-121-2/+0
| | | | | | | | | | This define is quite useful for debugging scene graph internals, but it is disabled by default to conserve memory. For clarity, I renamed the define to QSG_RUNTIME_DESCRIPTION.

* Enable sorting of opaque items again in the default renderer.Gunnar Sletta2013-02-051-3/+3
| | | | | | | | | | | This was disabled a long while back because we thought the code was broken, and it turned out the problem was that our sort function had a bug. b570d384c0704ea12364e353493eeb6f1ae34cd3 fixed the actual problem, so now we reenable it.

* Simplify the depth transformation in the scene graph.Kim Motoyoshi Kalland2012-05-251-10/+7
| | | | | | | | | | | | | Use default depth function GL_LESS and depth clear value 1, and set the near and far clipping planes to -1 and 1. This change will make the transformations a bit easier for people who implement custom 3D geometry since [-1, 1] is the typical z-range after a projection transformation. The change has no visual impact on 2D geometry.

* Provide determinant accessor in render state structure.Glenn Watson2012-02-081-0/+1
| | | | | | | | | | | This allows custom renderers to set the determinant to a value different than the actual model view transform matrix. This is useful when parts of the scene node transformation are done on the CPU rather than in the vertex shader.

* Say hello to QtQuick moduleKent Hansen2011-12-021-0/+527
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.
