Render thread -animations are able to run even when main (GUI) thread is blocked. The benefit of this is that -animations appear smooth in (almost) all situations. - -To compile plugin, some private Qt 5.0 headers are required. To get the plugin work correctly, -scenegraph adaptation must provide a non-blocking render loop. Default scenegraph implementation -does not currently have this feature enabled. If non-blocking render loop is not available, render -thread animations still work, but the animations are not smooth (just like normal QML animations) -when the main thread gets blocked. - -Usage QML examples can be found from the "examples" folder. Each example contains both, normal -animation and render-thread animation and some dummy code which tries to create high CPU-load -so that normal animations are stuttering while render-thread animations should keep running smoothly. - -Plugin exports 2 items and 7 animations which are named in the same way as the corresponding QtQuick -elements, so that taking the plugin into use is rather easy. At best cases, only minor modifications -to existing QML code is required. - - "Render-thread animation enabled" -versions of QML types currently are: - - Item - - ShaderEffect - - Render thread animation QML types: - - ColorAnimation - - NumberAnimation - - PauseAnimation - - ParallelAnimation - - PropertyAnimation - - SequentialAnimation - - Vector3DAnimation - -Limitations & differences to default QML animation system: - - - Only some of the QML Item properties to be animated inside render thread: - - Item: x, y, opacity, scale, rotation and arbitary transformations (Translate, Scale, Rotation). - - ShaderEffect: In addition to inherited Item properties, custom properties that have GLSL uniform - bindings can be animated in render thread. - - - Animations are executed asyncronously in the render thread, and the target property value is - written to the QML property only when animation completes. Only then the change becomes visible - to the Javascript bindings. - - - In the plugin functionality there are various issues that are not done in the most optimal way - for various reasons...hopefully the functionality will be included inside QtQuick itself in the - future Qt releases where it can be done in a more "correct" way. - - - - - - |
