* SceneGraph: Don't let QSGRenderNode::m_matrix be a dangling pointerAndy Nichols2023-03-171-2/+2
| | | | | | | | | | | | | | | | | Previously QSGRenderNode::m_matrix would be a dangling pointer most of the time. We document it as being valid during both the prepare, and render methods, but it would only be valid during the prepare phase. This was solved with the projectionMatrix by keeping a local copy instead of a pointer. No code was actually using the dangling pointer, but as a preventive measure since we document matrix as being valid also during the rhiRender we now have a local copy in QSGRenderNodePrivate, and manually set the pointer reference for the API, as well as a note to fix this non-ideal situtation in Qt 7.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| * | Improve dirty region calculation in software rendererJüri Valdmann2017-05-231-30/+47
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The software renderers dirty region calculation is done in integral logical coordinates, which leads to quite some trouble when handling scene graph elements with fractional coordinates (used by WebEngine for example). The optimal solution would probably be to either use integral physical coordinates or floating point logical coordinates, however this would seem to require substantial changes to QPainter and QBackingStore and so on. So, this patch instead changes the calculation to use something like interval arithmetic: instead of just rounding each logical coordinate to the nearest integer the renderer now uses (very carefully) both the upper and lower boundaries to make sure that the dirty regions always err on the side of caution. I expect this change to make rendering slower but only in situations where previously there would be rendering errors.

| | | | | | | | | | | | Having rendernodes triggering fullscreen updates with the software backend is not ideal. Therefore, introduce the option of reporting that the rendernode is well-behaving, meaning it only writes inside the reported bounding rectangle. Similarly, the OpenGL batch renderer can keep using the depth buffer when the rendernode is known to behave like the renderer expects.

* software: Add support for QSGRenderNodeLaszlo Agocs2016-07-191-6/+47
| | | | | | | | | | | | | | | | | Have to change getResource() a bit since it turns out it is not suitable currently for backends that do not have a per-window rendercontext and do not implement the interface on the rendercontext. Pass in the window to make sure it can always figure out which window we want the resources for. (we do not want rendererInterface() to return window-specific instances created on the fly, with ownership issues, so stick with the simple model where backends implement the interface on one of their existing classes) To support clipping, QSGRenderNode::RenderState is extended accordingly. Also updated the docs since some claims in the rendernode docs are not true since Qt 5.3. Change-Id: I34779c83926f5231b888fcab7131e873ae97964f Reviewed-by: Andy Nichols <andy.nichols@qt.io>

* Software Adaptation: Improve clip node handlingAndy Nichols2016-06-281-4/+10
| | | | | | | | | | | | | | | | This commit solves two issues that were coming up with nested clip nodes. The first was that determining the intersection of two or more nested clip nodes was calculated incorrectly. This was fixed by making sure the calculated clip region was in the correct coordinate space. The second issue was because there was no distinction between an empty unclipped region, and a completely clipped region. So a property was added to specify when a RenderableNode had a clipRegion so that the empty QRegion could be interpreted correctly. This makes sure that we don't end up drawing nodes that were culled. Change-Id: Id7af092f7fc6a4602b44b585b7dee14084136962 Reviewed-by: Laszlo Agocs <laszlo.agocs@qt.io>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | QSGSimpleRectNode is deprecated -> use QSGRectangleNode via QQuickWindow::createRectangleNode() instead. QSGSimpleTextureNode is deprecated -> use QSGImageNode via QQuickWindow::createImageNode() instead. The OpenGL version of the simple rectangle node is switched over to the vertex color material instead of flat, to allow for better batching. Use the same concept for nine patch nodes. The "style" node from Quick Controls 1 is now QSGNinePatchNode in order to provide a proper cross-backend solution which is already necessary due to the software backend, but now generalize it to apply to the accelerated backends with proper materials as well. QC can now simply call createNinePatchNode() without further ado. Also fixes a bug with the D3D12 texture material not enabling blending when needed. When it comes to the internal class names, QSGRectangleNode and QSGImageNode get the Internal prefix in the adaptation layer in order to differentiate from the public API. This involves quite a lot of renaming, but results in a nice and clean public API. Change-Id: Iddf9f9412377843ea6d652bcf25e68d1d74659ea Reviewed-by: Gunnar Sletta <gunnar@sletta.org>

* Enable building Qt Quick module with QT_NO_OPENGL definedAndy Nichols2016-03-221-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | 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.
