This example demonstrates implementing a - custom QQuickItem backed by a QSGRenderNode implementation, where the node - renders a triangle directly via the graphics API. The rest of the scene - (background, text, rectangles) are standard Qt Quick items. The example has - full support for OpenGL and Metal, as well as the software backend of Qt - Quick. - - The custom item behaves like any other Qt Quick item, meaning it - participates and stacking and clipping as usual, which is a big difference - to the alternative approaches like having the custom rendering as an - overlay (connecting to \l QQuickWindow::afterRendering()) and underlay - (connecting to \l QQuickWindow::beforeRendering()) because those do not - offer the possibility of proper mixing of the custom content with the Qt - Quick scene. - - Another important feature is that QSGRenderNode can be helpful to preserve - performance, when compared to some of the alternatives. Going through \l - QQuickFramebufferObject allows creating a custom item similarly to what - this example does, but it does it by rendering the custom content in a - texture, and then drawing a textured quad with that texture. This can be - expensive on some systems due to the cost of texturing and blending. - QSGRenderNode avoids this since the native graphics calls are issued in - line with the draw calls for the scene graph's batches. - - All this comes at the cost of being more complex, and not necessarily being - suitable for all types of 3D content, in particular where vertices and - different depth would clash with the 2D content in the Qt Quick scene - graph's batches (those are better served by "flattening" into a 2D texture - via approaches like QQuickFramebufferObject). Therefore QSGRenderNode is - not always the right choice. It can however a good and powerful choice in - many cases. This is what the example demonstrates. - - Let's go through the most important parts of the code: - - \snippet scenegraph/rendernode/customrenderitem.h 0 - - Our custom QML type is implemented in the class CustomRenderItem. - - \snippet scenegraph/rendernode/main.qml 2 - - The corresponding import in the QML document. - - \snippet scenegraph/rendernode/main.qml 3 - - The CustomRenderItem object. It is positioned to fill a big part of the - scene, covering its parent (the yellow rectangle; this will be used to - demonstrate clipping). The item will have its scale and rotation animated. - - \snippet scenegraph/rendernode/main.qml 4 - - Text items are used to show some helpful information, such as, the - active graphics API Qt Quick uses. - - \snippet scenegraph/rendernode/main.qml 5 - - Clicking the left mouse button is used to toggle clipping on the custom - item's parent item. By default this is done using scissoring (GL_SCISSOR_TEST - with OpenGL). A well-written QSGRenderNode implementation is expected to be - able to take this into account and enable scissor testing when the scene graph - indicates that it is necessary. - - The right mouse button is used to toggle an animation on the rotation of - the parent item. With clipping enabled, this demonstrates clipping via the - stencil buffer since a rectangular scissor is not appropriate when we need - to clip to a rotated rectangle shape. The scene graph fills up the stencil - buffer as necessary, the QSGRenderNode implementation just has to enable - stencil testing using the provided reference value. - - \snippet scenegraph/rendernode/customrenderitem.cpp 1 - - Moving on to the CustomRenderItem implementation. This is a visual item. - - \snippet scenegraph/rendernode/customrenderitem.cpp 2 - - The implementation of \l QQuickItem::updatePaintNode() creates (if not yet - done) and returns an instance of a suitable QSGRenderNode subclass. The - example supports multiple graphics APIs, and also the \c software backend. - - Let's look at the the render node for OpenGL (supporting both the - traditional, direct OpenGL-based scene graph, and also the modern, - abstracted variant using the RHI). For other graphics APIs, the concepts - and the outline of a QSGRenderNode implementation are the same. It is worth - noting that in some cases it will also be necessary to connect to a signal - like \l QQuickWindow::beforeRendering() to perform copy type of operations - (such as, vertex buffer uploads). This is not necessary for OpenGL, but it - is essential for Vulkan or Metal since there such operations cannot be - issued in render() as there is a renderpass being recorded when render() is - called. - - \snippet scenegraph/rendernode/openglrenderer.h 1 - - The main job is to provide implementations of the virtual QSGRenderNode functions. - - \snippet scenegraph/rendernode/openglrenderer.cpp 1 - - The pattern for safe graphics resource management is to do any cleanup in - \l{QSGRenderNode::releaseResources()}{releaseResources()}, while also - calling this from the destructor. - - \snippet scenegraph/rendernode/openglrenderer.cpp 2 - - The render() function initializes graphics resources (in this case, an - OpenGL shader program and a vertex buffer), if not yet done. It then - makes sure the necessary resources are bound and updates uniforms. - The transformation matrix and the opacity are provided by the scene graph - either via the \c state argument or base class functions. - - \snippet scenegraph/rendernode/openglrenderer.cpp 5 - - This render node is well-behaving since it basically renders in 2D, - respecting the item's geometry. This is not mandatory, but then flags() has - to return (or not return) the appropriate flags. - - \snippet scenegraph/rendernode/openglrenderer.cpp 3 - - After setting up vertex inputs, but before recording a draw call for our - triangle, it is important to set some state in order to integrate with the - rest of the scene correctly. Setting scissor and stencil as instructed by - \c state allows our item to render correctly even when there are one or - more clips in the parent chain. - - \snippet scenegraph/rendernode/openglrenderer.cpp 4 - - As shown above, we only really render in 2D (no depth), within the item's - geometry. changedStates() returns the flags corresponding to the OpenGL - states render() touches. - -*/ diff --git a/examples/quick/scenegraph/rendernode/main.cpp b/examples/quick/scenegraph/rendernode/main.cpp deleted file mode 100644 index 645360eaba..0000000000 --- a/examples/quick/scenegraph/rendernode/main.cpp +++ /dev/null @@ -1,87 +0,0 @@ -/**************************************************************************** -** -** Copyright (C) 2017 The Qt Company Ltd. -** Contact: https://www.qt.io/licensing/ -** -** This file is part of the examples of the Qt Toolkit. -** -** $QT_BEGIN_LICENSE:BSD$ -** Commercial License Usage -** Licensees holding valid commercial Qt licenses may use this file in -** accordance with the commercial license agreement provided with the -** Software or, alternatively, in accordance with the terms contained in -** a written agreement between you and The Qt Company.
