* Add renderTypeQuality property to Text elementEskil Abrahamsen Blomfeldt2020-08-171-1/+4
| | | | | | | | | | | | | | | | | | | | | For large scale text, the default distance field size gives artifacts on certain font features. We already have an environment variable which overrides this on an application level, but this will cause all distance fields to be rendered at the high resolution, whereas you may just want it for one particular text field. Since this becomes an especially important use case now that we can embed the text fields in a 3D scene, we add a property which can be used to tweak the base font size used for generating the distance fields. [ChangeLog][QtQuick][Text] Added "renderTypeQuality" property, which can be used in cases of very large fonts, where Qt's font rasterization may show some rendering artifacts when using the default quality.

* Do not create depth/stencil buffer when the env var says soLaszlo Agocs2020-08-161-0/+2
| | | | | | | | | | | | | | | | | | | | | | | Both for the swapchain and more importantly, layers. The latter was never implemented, not in Qt 5 with OpenGL either, and it becomes a problem for resource-limited use cases because QSG_NO_DEPTH_BUFFER still creates depth/stencil attachments for layers even though the 2D rendering has no use for those then. Clarify the QQuickGraphicsConfiguration docs as well. The story is fairly convoluted, because the useDepthFor2D flag one can set from C++ is not 100% the same as the env.var. (and it really should not be) The flag is about relying on depth testing in 2D (and so enabling the potentially more efficient opaque batches), but it does not prevent adding a View3D or other stuff that requires a depth buffer. The env.var on the other hand does both: it (depending on the platform) disables depth (and often stencil) buffers, thus using fewer resources, and also triggers the depth-less 2D rendering path (alpha batches only). But that is not always compatible with 3D then (like an offscren View3D will work, other modes may not) Change-Id: I5ac1ce154fe78a3ec8bd1a698c1c0b944ce8077e Reviewed-by: Andy Nichols <andy.nichols@qt.io>

* Expose the QRhiSwapchain via QSGRendererInterfaceLaszlo Agocs2020-06-031-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | ...similarly to how we already do it for the QRhi itself. Just follow the same pattern. This allows Qt Quick 3D to stop peeking directly into QQuickWindowPrivate and accessing member variables in there. Code like the following QQuickWindowPrivate *wd = QQuickWindowPrivate::get(window); QRhiCommandBuffer *cb = wd->swapchain->currentFrameCommandBuffer(); QRhiRenderPassDescriptor *rp = wd->rpDescForSwapchain; can now be written ca. like this, without pulling in quick-private: QRhiSwapChain *swapchain = window->rendererInterface->getResource(window, RhiSwapchain) QRhiCommandBuffer *cb = swapchain->currentFrameCommandBuffer(); QRhiRenderPassDescriptor *rp = swapchain->renderPassDescriptor(); This provides a more stable interface between the scenegraph and Quick 3D. In addition, this is also handy for manual tests, external test applications, etc. in case they do QRhi-based rendering in a QQuickWindow. Now these are also fine with just gui-private, no need to access QQuickWindowPrivate anymore. Change-Id: I921fb1c33c2fc77081272b1f180fdc2c87ed3ab5 Reviewed-by: Andy Nichols <andy.nichols@qt.io>

* rhi: Fix crashing Controls autotests due to shadereffect lifetime issuesLaszlo Agocs2020-05-131-6/+3
| | | | | | | | | | | | | | | | | | | | | Make the QSGShaderEffectNode base class a QObject, the subclass (QSGRhiShaderEffectNode) is already a QObject so we lose nothing. This way we can get rid of the textureChanged() signal from the shadereffectmanager (the object living on the gui thread), and so the node (living on the render thread) does not need to do emit m_mgr->textureChanged() on the render thread. The signal emission in itself was perfectly fine, except when m_mgr happened to be destroyed already in case the node outlived the gui thread's item (and m_mgr). After the change we have something that is closer to what the direct OpenGL implementation did - and some of the interfaces in QSGContext get a lot cleaner in fact because the node can be instantiated on its own, without the involving the shadereffectmanager object that does not even live on the render thread.

* Introduce new mechanism to manage palette functionality in QMLVitaly Fanaskov2020-03-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Main goals of these changes: 1) Add an ability to work with disabled and inactive palettes from QML 2) Eliminate massive code duplication in qtquickcontrols2 module 3) Provide easily extensible architecture for this piece of functionality Architectural part. Palette It was decided to not change existing QPalette, but add thin wrappers around it to provide all required functionality. These wrappers are highly coupled with QPalette class because of using some enum values from it. There are two new classes QQuickPalette and QQuickColorGroup. QQuickPalette class inherits QQuickColorGroup class and represents Active/All color group. QQuickPalette also provides an access to three color groups: Active, Inactive, and Disabled. In order to access colors the special class QQuickPaletteColorProvider is used. This is a wrapper around QPalette that provides some convenience functions. Interface The private property "palette" should be exposed. Implementation All private parts of classes that implement QQuickAbstractPaletteProvider have to inherit QQuickPaletteProviderPrivateBase class. This template class implement all functionality: create palette, resolve dependencies, connect objects etc. This is important to mention that related data is lazily allocatable on demand only. Hence, there is no memory overhead for regular items. Change-Id: I911424b730451b1ad47f68fd8007953b66eddb28 Reviewed-by: Volker Hilsheimer <volker.hilsheimer@qt.io>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Opt in via environment variables: QSG_RHI=1 -> enable using QRhi instead of GL QSG_RHI_BACKEND -> set to vulkan, metal, d3d11, gl to override the default (the default is d3d11 on Windows, metal on Mac, gl elsewhere) Or force a given rhi backend via the existing QQuickWindow::setSceneGraphBackend(). Otherwise the default behavior is the same as before, the rhi code path is never active by default. -no-opengl builds are supported in the sense that they work and default to the software backend. However, the rhi code path cannot currently be used in such builds, even though QRhi from qtbase is fully functional with Vulkan, D3D, or Metal even when qtbase was configured with -no-opengl. This cannot be utilized by Quick atm due to OpenGL usage being all over the place in the sources corresponding to the default backend, and those host the rhi code path as well. This will be cleaned up hopefully in Qt 6, with the removal all direct OpenGL usage. Other env.vars.: QSG_RHI_DEBUG_LAYER=1 -> enable D3D debug or Vulkan validation layer (assuming the system is set up for this) QSG_RHI_SHADEREFFECT_DEBUG=1 -> print stuff from ShaderEffect QSG_SAMPLES=1,2,4,... -> MSAA sample count (but QSurfaceFormat works too) QT_D3D_ADAPTER_INDEX=0,1,... -> D3D adapter index QT_VK_PHYSICAL_DEVICE_INDEX=0,1,... -> Vulkan physical device index QSG_RHI_UINT32_INDEX=1 -> always use uint index data (both merged/unmerged, convert when needed - with some rhi backends this is implicit) QSG_RENDER_LOOP -> to override the render loop as usual. The default with RHI is threaded for Metal, threaded for Vulkan on Windows, basic for Vulkan on Linux and Android (to be checked later), while the existing rules apply for OpenGL. Not supported when running with QRhi: - particles - compressed atlases (though this is transparent to the apps) - QSGRenderNode - QQuickRenderControl - QQuickFramebufferObject - certain QQuickWindow functionality that depends directly on OpenGL - anisotropic filtering for textures - native text may lack some gamma correction - QSGEngine applicability unclear - some QML profiler logs may be incorrect or irrelevant Change-Id: I7822e99ad79e342e4166275da6e9e66498d76521 Reviewed-by: Lars Knoll <lars.knoll@qt.io>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For non-OpenGL APIs the primary (and likely the only) way to add custom rendering into the Qt Quick scene is via the render node. Other approaches,like the before/afterRendering signals, QQuickFramebufferObject, remain OpenGL-only. (although QQuickFramebufferObject may get a multi-API replacement based on QSGRenderNode at a later time) Note that this is not a generic 3D content integration enabler. It targets creating 2D and 2.5D Quick items with custom rendering via the graphics API in use. Make QSGRenderNode public, enhance the docs a bit and add a releaseResources(). Add a QSGRendererInterface with a query function in QQuickWindow and QSGEngine. The scenegraph adaptation can then return a custom implementation of the interface. This will be necessary to query API-specific values, f.ex. the ID3D12Device and ID3D12CommandList when running with the d3d12 backend. The interface allows querying the API and void* resources. Resources that we know about in advance are enum-based to prevent the QPlatformNativeInterface-like ugliness of string keys. Support is there in the batch renderer already, fix this up according to the new public API, and implement the corresponding bits for the D3D12 renderer. For D3D12, fix also an issue with QSGNode destruction where graphics resources in use were attempted to be final-released without a proper wait. The semantics of changedStates() in QSGRenderNode is changed so that it can be called at any time, including before render(). This is very useful since we can implement some state restoring in a more efficient manner. Added a new example as well. Documentation for QSGRenderNode is heavily expanded.

* Enable building Qt Quick module with QT_NO_OPENGL definedAndy Nichols2016-03-221-0/+243
Currently the Qt Quick module depends on either the OpenGL or OpenGLES headers being available at build time. Since we are adding support for adaptations that do not depend on OpenGL, it should be possible to build Qt Quick in environments that do not have OpenGL development headers. This does present many challenges though because in some cases GL types, and classes that require OpenGL are part of the public APIs. However since these classes were never available when QT_NO_OPENGL was defined, it should be possible to redefine the function signatures under this scenario, since it's not possible to break binary compatibility if there never were any binaries to break compatibility with. One of the bigger changes that was necessary to facilitate this change is creating interfaces out of QSGContext and QSGRenderContext. Here the default behavior was usage of OpenGL directly, even though subclasses could override all OpenGL usage. Making them interfaces should bring QSGContext and QSGRenderContext more in line with the other classes present in the adaptation layer.
